Google Workspace MCP Server - Control Gmail, Calendar, Docs, Sheets, Slides, Chat, Forms & Drive

Google Workspace MCP Server

License: MIT Python 3.10+ PyPI PyPI Downloads MCP Toplist Website

Full natural language control over Google Calendar, Drive, Gmail, Docs, Sheets, Slides, Forms, Tasks, Contacts, and Chat through all MCP clients, AI assistants and developer tools. Includes a full featured CLI & Code Mode for use with tools like Claude Code and Codex!

The fastest, most feature-complete Google Workspace MCP server is in a class of it's own: it can do things that Google's own tooling and the built in integrations with Claude and ChatGPT can't come close to with multi-user support, rich fine-grained editing tools and the most extensive coverage of any Workspace AI integration in existence.

By leveraging native OAuth 2.1, stateless deployment capability and external auth server & gateway passthrough auth support, it's also the only Workspace MCP you can host for your whole organization centrally & securely! Supports all free Google accounts & Google Workspace plans with expanded app options like Chat & Spaces.


See it in action:


What It Does

Workspace MCP connects AI assistants to all twelve major Google Workspace services - 120+ tools behind a single MCP server, with OAuth 2.1 multi-user auth, three progressive tool tiers, read-only mode, a full CLI, and stateless container deployment. It runs locally over stdio for legacy clients and remotely over streamable HTTP with full implementation of the latest MCP spec.

The README covers just enough to get you running, with extensive documentation on the website:

Security & Compliance

For Security Teams

By default, this server sends no data anywhere except Google's APIs, on behalf of the authenticated user, using your own OAuth client credentials. There is no usage reporting, analytics, license server, or SaaS dependency outside optional OTel support for your own usage.

  • Fully open source — every line is auditable in this repo

  • Your OAuth client, your GCP project — credentials never leave your environment & you control scopes

  • You control the network — deploy behind your reverse proxy, in your VPC, on your own terms

  • Stateless mode — zero disk writes for locked-down container environments

  • Sensitive path blocking — local file reads default to the managed attachment directory, and validate_file_path() still blocks .env* files plus common home-directory credential stores such as ~/.ssh/ and ~/.aws/ even if ALLOWED_FILE_DIRS is broadened

Full dependency tree in pyproject.toml, pinned in uv.lock.

For Legal & Procurement

This project is MIT licensed —

  • Use commercially without restriction — build products, sell services, deploy internally

  • Fork, embed, redistribute — MIT requires only attribution

  • No CLA — contributions remain under MIT

  • No built-in telemetry to disclose — optional tracing is off unless you configure it

  • No network effects — the server never contacts any endpoint you didn't configure

  • Standard dependency licenses — MIT, Apache 2.0, and BSD throughout the dependency chain; no copyleft, no AGPL

Services

Each page lists every tool with its tier, parameters, required scopes, and example prompts. The complete reference covers all twelve in one place.

💬 Google Chat needs a one-time Chat app configuration and a Workspace account - see the Chat setup FAQ.

Quick Start

Set credentials → pick a launch command → connect your client. Full walkthrough with screenshots: workspacemcp.com/quick-start

You'll need an OAuth client from Google Cloud Console in a project with the Google APIs enabled for the services you plan to use. The docs have one-click enable links for every API plus a single gcloud services enable command that covers them all, and the quick start guide walks through the whole setup in about five minutes.

Agentic OAuth clients: this server only calls Google's REST APIs, so your OAuth client does not need Google's "Use this client for an AI-powered agent" setting. If your organization wants agent traffic labeled for admin controls, create a separate client with that setting enabled; it can't be changed on an existing client after November 12, 2026.

Confidential Client

# 1. Credentials
export GOOGLE_OAUTH_CLIENT_ID="..."
export GOOGLE_OAUTH_CLIENT_SECRET="..."

# 2. Launch - pick a tier
uvx workspace-mcp --tool-tier core       # essential tools
uvx workspace-mcp --tool-tier extended   # core + management ops
uvx workspace-mcp --tool-tier complete   # everything

# Or cherry-pick services
uvx workspace-mcp --tools gmail drive calendar

OAuth 2.1 (PKCE)

# 1. Credentials - MCP clients connect with PKCE and no
#    secret, but Google still requires one server-side
export MCP_ENABLE_OAUTH21=true
export GOOGLE_OAUTH_CLIENT_ID="..."
export GOOGLE_OAUTH_CLIENT_SECRET="..."
#    Alternatively, point GOOGLE_CLIENT_SECRET_PATH at a client_secret.json
#    that contains the client id and secret (env vars take precedence).
export WORKSPACE_MCP_PORT=8000
export GOOGLE_OAUTH_REDIRECT_URI="http://localhost:${WORKSPACE_MCP_PORT}/oauth2callback"
export OAUTHLIB_INSECURE_TRANSPORT=1

# 2. Launch - OAuth 2.1 requires HTTP transport
uvx workspace-mcp --transport streamable-http --tool-tier core

Tool tiers keep context windows lean: core is the essential set, extended adds management operations, complete loads everything. Combine with --tools <service> ..., --read-only, or per-service --permissions, and subtract individual tools with --disabled-tools <name> ... - details in the server modes docs.

Per-request toolsets let HTTP clients sharing one server see different tools, using the same headers as the GitHub MCP server. X-MCP-Toolsets takes comma-separated service names (the --tools names, e.g. gmail,drive) and X-MCP-Tools takes comma-separated tool names (e.g. search_gmail_messages); when both are sent the request gets the union. Names ignore case and whitespace, unknown names match nothing, and a blank or missing header leaves the tool list unchanged. Headers only narrow what the server already loaded: a tool removed by the tier, --tools, --read-only, --permissions or --disabled-tools stays unavailable, and calls to tools outside the request's selection fail as unknown tools.

Connect Your Client

Claude Desktop, web & mobile - run the server in HTTP mode and add it as a Connector (Settings → Connectors → Add custom connector). This is the recommended path; the Connector guide has step-by-step screenshots. Legacy stdio configuration remains available for clients without Connector support - see the FAQ.

Claude Code

# Start the server in HTTP mode, then:
claude mcp add --transport http workspace-mcp http://localhost:8000/mcp

# Optional: install the bundled skill for better Workspace tool routing
ln -s "$(pwd)/skills/managing-google-workspace" ~/.claude/skills/managing-google-workspace

ChatGPT - connect via Developer Mode with the ChatGPT guide.

VS Code, LM Studio, Open WebUI, and everything else - any MCP client works over streamable HTTP (recommended) or stdio. Client-specific walkthroughs live in the guides and FAQ.

CLI

workspace-cli lists and calls tools against a running server with encrypted, disk-backed OAuth token caching - authenticate once, script forever:

uv run workspace-cli list
uv run workspace-cli call search_gmail_messages query="is:unread" max_results=5

Install globally with uv tool install . from this repo. ⚠️ Don't use uvx workspace-cli - an abandoned PyPI package squats that name.

Deployment & Advanced Configuration

Everything you need to run this in production lives in two places. The documentation covers auth modes and server configuration:

The Advanced Deployment guide covers self-hosting specifics: reverse proxy setup with WORKSPACE_EXTERNAL_URL (including the nginx Origin: null consent workaround, the WORKSPACE_MCP_ALLOW_NULL_ORIGIN_CONSENT escape hatch, and the Referrer-Policy pitfall), origin validation and VS Code webview allowlisting, credential store backends (local directory or GCS with CMEK enforcement), and the complete environment variable reference.

Production tuning is all environment variables; the names below link to their reference entries.

  • Google API requests: WORKSPACE_MCP_GOOGLE_API_WORKERS, WORKSPACE_MCP_GOOGLE_API_TIMEOUT_SECONDS

  • External OAuth token validation: WORKSPACE_MCP_TOKEN_VALIDATION_WORKERS, WORKSPACE_MCP_TOKEN_VALIDATION_CACHE_TTL

  • Memory ceilings: WORKSPACE_MCP_MAX_FILE_BYTES, WORKSPACE_MCP_STATELESS_INLINE_MAX_BYTES, WORKSPACE_MCP_MAX_OFFICE_XML_BYTES

  • Text returned per call: get_drive_file_content returns long content a page at a time by default, so a long file does not fill the model's context. WORKSPACE_MCP_MAX_CONTENT_CHARS sets the page size (default 40000; 0 returns whole content by default). Each page ends with a note giving the offset to read on from. This is only the default: a client can always pass full_content=true to get the whole file in one call. Text being read page by page is kept in memory for ten minutes so later pages are not downloaded again, within WORKSPACE_MCP_PAGED_CONTENT_CACHE_BYTES per process (default 33554432, 32 MiB; 0 keeps nothing).

  • Sessions and health probes: WORKSPACE_MCP_SESSION_IDLE_TIMEOUT, WORKSPACE_MCP_READINESS_TIMEOUT_SECONDS

  • DNS-rebinding protection: WORKSPACE_MCP_ALLOWED_HOSTS, a comma-separated list of hostnames without ports (for example workspace-mcp,10.0.0.5). When set, requests whose Host is not loopback, listed, or the host of WORKSPACE_EXTERNAL_URL or an allowed origin get 403, so include every name clients and health probes use. Unset, any Host is accepted.

  • Hosted servers without access to the caller's disk: WORKSPACE_MCP_DISABLE_LOCAL_FILES With local files disabled, create_drive_file, update_drive_file and the import tools offer return_upload_url: the caller PUTs the bytes to the returned URL. If the file sits in a cloud-mirrored folder (Drive for desktop), copy it to a local directory first, since mirrored paths can stall mid-upload.

  • OAuth 2.1 token refresh and lifetimes: see .env.oauth21

  • OAuth 2.1 consent screen: WORKSPACE_MCP_OAUTH_PROXY_REQUIRE_CONSENT=remember shows the OAuth proxy's consent screen once per browser for each MCP client instead of on every authorization; cross-site navigations are still prompted. The default, always, prompts every time. Any other value fails startup.

  • OAuth 2.1 Google account choice: WORKSPACE_MCP_OAUTH_PROXY_GOOGLE_PROMPT sets the prompt the OAuth proxy sends to Google's authorization endpoint (default consent); external provider mode ignores it. select_account consent shows Google's account chooser, so a user signed in to Google with another account can pick the right one, and still returns a refresh token. The only other accepted value is consent; anything else fails startup.

For downloads, horizontally scaled or scale-to-zero HTTP deployments (Cloud Run, Kubernetes) can stage attachments in Google Cloud Storage instead of instance-local disk, whose /attachments/{id} URL may reach a different instance. Install the gcs extra and set WORKSPACE_MCP_FILES_GCS_BUCKET to a bucket name; objects are written under WORKSPACE_MCP_FILES_GCS_PREFIX (default attachments) and handed out as V4 signed URLs valid for one hour, which the client fetches straight from GCS. This also lets stateless mode return download URLs instead of inline files. stdio ignores the setting, since its client reads the local file path directly. The runtime service account needs object read and write access on the bucket — roles/storage.objectUser, or roles/storage.objectCreator plus roles/storage.objectViewer — and, without an exported private key, roles/iam.serviceAccountTokenCreator on itself so URLs can be signed through IAM. Read access is not optional: a signed URL carries the signer's authority, so without storage.objects.get the upload and the signing both succeed while the client's download fails with 403. Objects are not deleted by the server, so add a bucket lifecycle rule that removes them after a few hours.

Security Best Practices

By default this server sends no data anywhere except Google's APIs, using your own OAuth client credentials - no usage reporting, analytics, license server, or SaaS dependency. MIT licensed with no CLA, no dual licensing, and no copyleft in the dependency chain. The full security posture - scope minimization, sensitive-path blocking, stateless mode - is documented at workspacemcp.com.

A few things worth internalizing before you connect an LLM to your email:

  • Prompt injection is real. Emails, docs, and events can contain hidden instructions. Only connect trusted data to an LLM, and be deliberate about which write tools you enable.

  • Never commit .env, client_secret.json, or .credentials/ to source control.

  • Local file reads are sandboxed to the managed attachment directory. Broaden with ALLOWED_FILE_DIRS only if you trust the client and its data sources; .env*, ~/.ssh/, ~/.aws/, and similar paths are always blocked.

  • Production deployments should use HTTPS and OAuth 2.1.

Validations: MCP Badge

Available Tools

119 tools
append_table_rowsAppend Table RowsA

Appends rows to a structured table in a Google Sheet. The rows are added to the end of the table body, automatically extending the table range.

Use list_sheet_tables first to find the table ID.

Inputs: values (required), table_id (required), spreadsheet_id (required), user_google_email (required). Returns: result

batch_modify_gmail_message_labelsBatch Modify Gmail Message LabelsA
Destructive

Adds or removes labels on many Gmail messages, or on every message of whole conversations via thread_ids.

message_ids are sent in one users.messages.batchModify call (Gmail accepts up to 1000 ids per call). That endpoint returns no per-message result and silently ignores ids it does not recognise, so by default the messages are read back afterwards to report which ids actually changed.

thread_ids are modified one at a time with users.threads.modify, e.g. archive a conversation with remove_label_ids=["INBOX"] or mark it read with remove_label_ids=["UNREAD"]. Each thread reports its own outcome. message_ids and thread_ids can be combined; at least one is required, as is at least one of add_label_ids or remove_label_ids.

Inputs: user_google_email (required), verify, thread_ids, message_ids, +2 more. Returns: result

batch_update_docBatch Update DocA
Destructive

Executes multiple low-level document operations in a single atomic batch update.

For normal header/footer text, prefer update_doc_headers_footers. Only use create_header_footer here for advanced section-break layouts.

RECOMMENDED WORKFLOW FOR BUILDING DOCUMENTS:

To avoid index calculation errors, build documents in phases:

PHASE 1 - INSERT ALL CONTENT (use end_of_segment=true, no index math): Append text, section breaks, and page breaks sequentially. Each operation appends to the end of the body. No index needed. Example batch: [ {"type": "insert_text", "end_of_segment": true, "text": "Report Title\n"}, {"type": "insert_text", "end_of_segment": true, "text": "\nExecutive Summary\n"}, {"type": "insert_text", "end_of_segment": true, "text": "Revenue grew 15%.\n"}, {"type": "insert_section_break", "end_of_segment": true, "section_type": "NEXT_PAGE"}, {"type": "insert_text", "end_of_segment": true, "text": "Detailed Analysis\n"} ]

PHASE 2 - CREATE HEADERS/FOOTERS (if needed): For normal header/footer text, use update_doc_headers_footers (it auto-creates if missing and writes the content for you). Only include create_header_footer operations in a batch when you are intentionally managing advanced section-break-specific layouts.

Inputs: operations (required), document_id (required), user_google_email (required). Returns: result

batch_update_formBatch Update FormA
Destructive

Apply batch updates to a Google Form.

Supports adding, updating, and deleting form items, as well as updating form metadata and settings. This is the primary method for modifying form content after creation.

Inputs: form_id (required), requests (required), user_google_email (required). Returns: result

batch_update_presentationBatch Update PresentationC
Destructive

Apply batch updates to a Google Slides presentation.

Inputs: requests (required), presentation_id (required), user_google_email (required). Returns: result

check_drive_file_public_accessCheck Drive File Public AccessA
Read-onlyIdempotent

Searches for a file by name and checks if it has public link sharing enabled.

Inputs: file_name (required), user_google_email (required), drive_id. Returns: result

copy_drive_fileCopy Drive FileB

Creates a copy of an existing Google Drive file.

This tool copies the template document to a new location with an optional new name. The copy maintains all formatting and content from the original file.

Inputs: file_id (required), user_google_email (required), new_name, copy_comments, +1 more. Returns: result

create_docCreate DocA

Creates a new Google Doc and optionally inserts initial content.

content is inserted as plain text (Markdown is not rendered); use import_to_google_doc to create a doc from Markdown.

After creation, the document body starts at index 1. A new empty doc has total length 2 (one section break at index 0, one newline at index 1).

To build a rich document after creation, use batch_update_doc with insert_text operations using end_of_segment=true to append content sequentially without calculating indices. Then call inspect_doc_structure to get exact positions before applying formatting in a separate batch call.

Inputs: title (required), user_google_email (required), content, folder_id. Returns: result

create_drive_fileCreate Drive FileA

Creates a new file in Google Drive, supporting creation within shared drives. Accepts direct text content, inline base64 bytes, or a fileUrl to fetch content from. Where local file access is disabled it can instead return an upload URL for the caller to PUT file bytes to. With shortcut_target_id it creates a Drive shortcut to an existing file or folder instead. This stores the supplied bytes without converting them to Google Docs, Sheets, or Slides. Use the matching import_to_google_* tool for Google-native conversion.

Inputs: file_name (required), user_google_email (required), content, fileUrl, +6 more. Returns: result

create_drive_folderCreate Drive FolderA

Creates a new folder in Google Drive, supporting creation within shared drives.

Inputs: folder_name (required), user_google_email (required), parent_folder_id. Returns: result

create_formCreate FormB

Create a new form using the title given in the provided form message in the request.

Inputs: title (required), user_google_email (required), description, document_title. Returns: result

create_presentationCreate PresentationB

Create a new Google Slides presentation.

Inputs: user_google_email (required), title. Returns: result

create_reactionCreate ReactionA

Adds an emoji reaction to a Google Chat message.

Inputs: message_id (required), emoji_unicode (required), user_google_email (required). Returns: result

create_sheetCreate SheetC

Creates a new sheet or duplicates an existing sheet, into destination_spreadsheet_id when given (user_google_email: str, spreadsheet_id: str, sheet_name: Optional[str] = None, source_sheet_name: Optional[str] = None, insert_sheet_index: Optional[int] = None, destination_spreadsheet_id: Optional[str] = None).

Inputs: spreadsheet_id (required), user_google_email (required), sheet_name, source_sheet_name, +2 more. Returns: result

create_spreadsheetCreate SpreadsheetC

Creates a new Google Spreadsheet.

Inputs: title (required), user_google_email (required), folder_id, sheet_names. Returns: result

create_table_with_dataCreate Table with DataA

Creates a table and populates it with data in one reliable operation.

CRITICAL: YOU MUST CALL inspect_doc_structure FIRST TO GET THE INDEX!

MANDATORY WORKFLOW - DO THESE STEPS IN ORDER:

Step 1: ALWAYS call inspect_doc_structure first Step 2: Use the 'total_length' value from inspect_doc_structure as your index Step 3: Format data as 2D list: [["col1", "col2"], ["row1col1", "row1col2"]] Step 4: Call this function with the correct index and data

EXAMPLE DATA FORMAT: table_data = [ ["Header1", "Header2", "Header3"], # Row 0 - headers ["Data1", "Data2", "Data3"], # Row 1 - first data row ["Data4", "Data5", "Data6"] # Row 2 - second data row ]

CRITICAL INDEX REQUIREMENTS:

  • NEVER use index values like 1, 2, 10 without calling inspect_doc_structure first

  • ALWAYS get index from inspect_doc_structure 'total_length' field

  • Index must be a valid insertion point in the document

DATA FORMAT REQUIREMENTS:

  • Must be 2D list of strings only

  • Each inner list = one table row

  • All rows MUST have same number of columns

  • Use empty strings "" for empty cells, never None

  • Use debug_table_structure after creation to verify results

Inputs: index (required), table_data (required), document_id (required), user_google_email (required), +3 more. Returns: result

debug_table_structureDebug Table StructureA
Read-onlyIdempotent

ESSENTIAL DEBUGGING TOOL - Use this whenever tables don't work as expected.

USE THIS IMMEDIATELY WHEN:

  • Table population put data in wrong cells

  • You get "table not found" errors

  • Data appears concatenated in first cell

  • Need to understand existing table structure

  • Planning to fill existing cells with modify_doc_text at their insertion_index

WHAT THIS SHOWS YOU:

  • Exact table dimensions (rows × columns)

  • Each cell's position coordinates (row,col)

  • Current content in each cell

  • Insertion indices for each cell

  • Table boundaries and ranges

HOW TO READ THE OUTPUT:

  • "dimensions": "2x3" = 2 rows, 3 columns

  • "position": "(0,0)" = first row, first column

  • "current_content": What's actually in each cell right now

  • "insertion_index": Where new text would be inserted in that cell

WORKFLOW INTEGRATION:

  1. After creating table → Use this to verify structure

  2. Before populating → Use this to plan your data format

  3. After population fails → Use this to see what went wrong

  4. When debugging → Compare your data array to actual table structure

Inputs: document_id (required), user_google_email (required), tab_id, table_index. Returns: result

download_chat_attachmentDownload Chat AttachmentA

Downloads an attachment from a Google Chat message and saves it to local disk.

In stdio mode, returns the local file path for direct access. In HTTP mode, returns a temporary download URL (valid for 1 hour).

Inputs: message_id (required), user_google_email (required), attachment_index. Returns: result

draft_gmail_messageDraft Gmail MessageA

Creates a draft email in the user's Gmail account. Supports new, reply, and forward drafts with optional attachments. Supports Gmail's "Send As" feature to draft from configured alias addresses.

To save a forward as a draft for review, pass forward_message_id. The original subject, body (quoted with a "Forwarded message" header), and attachments are carried over. In forward mode, body (if any) is prepended as a note, subject is optional, and threading, reply, and signature options do not apply.

SCHEDULED SEND IS NOT AVAILABLE. Gmail's REST API exposes no send-time parameter; the Schedule send feature is web-UI only, and a message cannot be placed in the Scheduled folder through the API. Do not claim a message was scheduled. To deliver at a chosen time, create a draft with draft_gmail_message. An external scheduler must retain the message data to create and send a new message via send_gmail_message then, or call users.drafts.send with the draft ID returned by draft_gmail_message. Alternatively, let the user schedule the draft in the Gmail UI.

Inputs: user_google_email (required), cc, to, bcc, +15 more. Returns: result

export_doc_to_pdfExport Doc to PDFA

Exports a Google Doc to PDF format and saves it to Google Drive.

Inputs: document_id (required), user_google_email (required), folder_id, pdf_filename. Returns: result

find_and_replace_docFind and Replace DocA
Destructive

Finds and replaces text throughout a Google Doc. No index calculation required.

This is the safest way to update specific text in a document because it does not require knowing any indices. Use this tool when you need to:

  • Replace placeholder text (e.g., {{TITLE}}) with real content

  • Update specific words or phrases throughout the document

  • Make targeted text changes without risk of index errors

For building documents from scratch, consider inserting text with unique placeholders via batch_update_doc, then using this tool to replace them.

Inputs: find_text (required), document_id (required), replace_text (required), user_google_email (required), +2 more. Returns: result

format_sheet_rangeFormat Sheet RangeB
Destructive

Applies formatting to a range: colors, number formats, text wrapping, alignment, text styling, cell merging/unmerging, borders, and dropdown lists.

Colors accept hex strings (#RRGGBB). Number formats follow Sheets types (e.g., NUMBER, CURRENCY, DATE, PERCENT). If no sheet name is provided, the first sheet is used.

Inputs: range_name (required), spreadsheet_id (required), user_google_email (required), bold, +17 more. Returns: result

generate_trigger_codeGenerate Trigger CodeA
Read-onlyIdempotent

Generates Apps Script code for creating triggers.

The Apps Script API cannot create triggers directly - they must be created from within Apps Script itself. This tool generates the code you need. To list or remove existing triggers without opening the editor, use manage_script_trigger (action="list" / action="delete") instead.

Inputs: trigger_type (required), function_name (required), schedule. Returns: result

get_contactGet ContactA
Read-onlyIdempotent

Get detailed information about a specific contact.

Inputs: contact_id (required), user_google_email (required). Returns: result

get_contact_groupGet Contact GroupA
Read-onlyIdempotent

Get details of a specific contact group including its members.

Inputs: group_id (required), user_google_email (required), max_members. Returns: result

get_doc_as_markdownGet Doc as MarkdownA
Read-onlyIdempotent

Reads a Google Doc and returns it as clean Markdown with optional comment context.

Unlike get_doc_content which returns plain text, this tool preserves document formatting as Markdown: headings, bold/italic/strikethrough, links, code spans, ordered/unordered lists with nesting, and tables.

When comments are included (the default), each comment's anchor text — the specific text the comment was attached to — is preserved, giving full context for the discussion.

Inputs: document_id (required), user_google_email (required), tab_id, heading, +6 more. Returns: result

get_doc_contentGet Doc ContentA
Read-onlyIdempotent

Retrieves content of a Google Doc or a Drive file (like .docx) identified by document_id.

  • Native Google Docs: Fetches content via Docs API.

  • Office files (.docx, etc.) stored in Drive: Downloads via Drive API and extracts text.

By default, native Google Docs text is index-aligned with the document: empty paragraphs are preserved and every non-text element that occupies an index (inline object, page break, footnote reference, ...) is rendered as one U+FFFC placeholder per index. The document body starts at index 1, so an offset n into the text that follows "--- CONTENT ---" is document index n + 1, and that index can be passed straight to format_text or delete_text. Tables and multi-tab documents interleave separators, so alignment holds up to the first table or tab header.

Set preserve_context=True for readable link destinations, internal targets, smart-chip values, table boundaries, headers, footers, footnotes, and object context exposed by the Docs API. This output is plain text, not Markdown, and its offsets must not be used as document editing indices. Comments, revision history, exact visual layout, and chip details hidden by the API are not included. Use get_doc_as_markdown for formatting or comments.

Inputs: document_id (required), user_google_email (required), tab_id, heading, +3 more. Returns: result

get_drive_file_contentGet Drive File ContentA
Read-onlyIdempotent

Retrieves the content of a specific Google Drive file by ID, supporting files in shared drives.

• Native Google Docs, Sheets, Slides → exported as text / CSV. • Office files (.docx, .xlsx, .pptx) → unzipped & parsed with std-lib to extract readable text. • PDFs → text extracted with pypdf when possible; scanned/image-only PDFs fall back to a download hint. • Images (PNG, JPEG, GIF, WebP) → returned as MCP image content after the metadata header. SVG → returned as its markup; raster images it embeds as base64 are attached as image content, numbered to match their place in the markup. BMP and TIFF → base64 text, or a download hint when over the default page size. • Any other file → downloaded; tries UTF-8 decode, else notes binary.

Inputs: file_id (required), user_google_email (required), offset, full_content. Returns: result

get_drive_file_download_urlGet Drive File Download URLA
Read-onlyIdempotent

Downloads a Google Drive file and saves it to local disk.

In stdio mode, returns the local file path for direct access. In HTTP mode, returns a temporary download URL (valid for 1 hour). In stateless mode (no file storage), returns the file itself as an embedded resource, up to WORKSPACE_MCP_STATELESS_INLINE_MAX_BYTES (default 10 MiB, and never more than WORKSPACE_MCP_MAX_FILE_BYTES when that is set).

For Google native files (Docs, Sheets, Slides, Drawings), exports to a useful format:

  • Google Docs -> PDF (default) or DOCX if export_format='docx'

  • Google Sheets -> XLSX (default), PDF if export_format='pdf', or CSV if export_format='csv'

  • Google Slides -> PDF (default) or PPTX if export_format='pptx'

  • Google Drawings -> PNG (default), or PDF, JPG or SVG if export_format='pdf', 'jpg' or 'svg'

For other files, downloads the original file format.

Inputs: file_id (required), user_google_email (required), export_format. Returns: result

get_drive_file_permissionsGet Drive File PermissionsA
Read-onlyIdempotent

Gets detailed metadata about a Google Drive file including sharing permissions, parent folder IDs, ownership, and lifecycle timestamps.

Inputs: file_id (required), user_google_email (required). Returns: result

get_eventsGet EventsA
Read-onlyIdempotent

Retrieves events from a specified Google Calendar. Can retrieve a single event by ID or multiple events within a time range. You can also search for events by keyword by supplying the optional "query" param.

Inputs: user_google_email (required), query, detailed, event_id, +7 more. Returns: result

get_formGet FormC
Read-onlyIdempotent

Get a form.

Inputs: form_id (required), user_google_email (required). Returns: result

get_form_responseGet Form ResponseB
Read-onlyIdempotent

Get one response from the form.

Inputs: form_id (required), response_id (required), user_google_email (required). Returns: result

get_gmail_attachment_contentGet Gmail Attachment ContentA

Downloads an email attachment and saves it to local disk.

In stdio mode, returns the local file path for direct access. In HTTP mode, returns a temporary download URL (valid for 1 hour). May re-fetch message metadata to resolve filename and MIME type.

Inputs: message_id (required), attachment_id (required), user_google_email (required), return_base64, +1 more. Returns: result

get_gmail_message_contentGet Gmail Message ContentA
Read-onlyIdempotent

Retrieves the full content (subject, sender, recipients, body) of a specific Gmail message.

Set page_offset=0 to read the complete rendered body, excluding attachments and attached messages, as JSON pages of at most page_size characters. Follow next_offset until complete=true, passing body_sha256 as expected_sha256 and keeping body_format and include_links unchanged.

Bodies are returned inline and truncated at 20,000 characters. Set full=True to get the complete, untruncated message instead: it is exported to storage and the response carries a short-lived download URL (HTTP transport) or file path (stdio transport) rather than the body, so large messages never stream through the model context. Stateless deployments without GCS staging have no storage, so there full=True returns the untruncated body inline; with GCS staging configured it returns a signed download URL like any other HTTP deployment.

Inputs: message_id (required), user_google_email (required), full, format, +6 more. Returns: result

get_gmail_messages_content_batchGet Gmail Messages Content BatchA
Read-onlyIdempotent

Retrieves the content of multiple Gmail messages in a single batch request. Supports up to 25 messages per batch to prevent SSL connection exhaustion.

Inputs: index (required), document_id (required), image_source (required), user_google_email (required), +2 more. Returns: result

inspect_doc_structureInspect Doc StructureA
Read-onlyIdempotent

Essential tool for finding safe insertion points and understanding document structure.

USE THIS FOR:

  • Finding the correct index for table insertion

  • Understanding document layout before making changes

  • Locating existing tables and their positions

  • Getting document statistics and complexity info

  • Inspecting structure of specific tabs

CRITICAL FOR TABLE OPERATIONS: ALWAYS call this BEFORE creating tables to get a safe insertion index.

WHAT THE OUTPUT SHOWS:

  • total_elements: Number of document elements

  • total_length: Maximum safe index for insertion

  • tables: Number of existing tables

  • table_details: Position and dimensions of each table

  • headers / footers: Real segment IDs and previews for header/footer editing

  • tabs: List of available tabs in the document (if no tab_id specified)

  • empty_paragraphs: newline-only count, excluding existing/suggested object anchors

  • empty_paragraph_ranges: start/end extents, capped at 100

  • empty_paragraph_ranges_truncated: whether ranges were omitted

  • last_paragraph: is_list_item and is_empty, or null if no body paragraphs

Paragraph statistics cover top-level body paragraphs and appear at the top level in basic mode or under "statistics" in detailed mode. Ranges can include required empty paragraphs. Before cleanup, use detailed=true to check adjacent elements, formatting, and object anchors. Preserve the final newline and newlines before tables, tables of contents, or section breaks. If the body ends with an empty paragraph, that paragraph's range has end == total_length; truncation may omit that range.

WORKFLOW FOR TABLE INSERTION: Step 1: Call this function Step 2: Note the "total_length" value Step 3: Use an index < total_length for table insertion Step 4: Create your table

FORMATTING WORKFLOW: After inserting all text via batch_update_doc with end_of_segment=true, call this tool with detailed=true to get exact start_index and end_index for every paragraph. Use those indices directly in format_text and update_paragraph_style operations in a second batch_update_doc call.

HEADER/FOOTER WORKFLOW: For ordinary header/footer text, use update_doc_headers_footers. If you need low-level segment editing, call this tool first and use the real segment_id values returned under headers/footers. Do not invent IDs.

The detailed output includes elements[].start_index and elements[].end_index with text_preview for each paragraph, making it easy to identify which ranges to format.

SUB-PARAGRAPH FORMATTING: text_preview is truncated to 100 characters by default. To compute the index of a token inside a longer paragraph, pass preview_chars=0 or None for untruncated text, then add the token's UTF-16 offset within that text to the paragraph's start_index (non-BMP characters such as emoji occupy two UTF-16 units).

Inputs: document_id (required), user_google_email (required), tab_id, detailed, +1 more. Returns: result

manage_gmail_filterManage Gmail FilterA
Destructive

Manages Gmail filters: create, delete, update, and apply to existing mail.

  • update: Gmail has no filter update API, so the filter is recreated (new one first, then the old one is deleted) and its ID changes. A passed criteria or filter_action replaces that whole object; omit one to keep the old filter's.

  • apply: runs a filter's label actions on mail ALREADY in the mailbox (Gmail filters only act on new mail). Only matching messages change, not whole conversations as in the web UI. Use filter_id, or criteria + filter_action for an ad-hoc run. Forwarding is never applied. Use dry_run=true first to see the search query and the match count. Needs the gmail.modify scope in addition to gmail.settings.basic.

Inputs: action (required), user_google_email (required), dry_run, criteria, +3 more. Returns: result

Inputs: action (required), user_google_email (required), title, parent_id, +1 more. Returns: result

manage_script_triggerManage Script TriggerA
Destructive

List or delete the current user's installable triggers on a script project.

The Apps Script REST API has no triggers resource, so in dev_mode both actions provision (or refresh) a small helper file and run it via the Execution API - the only way to inspect or change trigger state without opening the editor. Neither action is read-only: the helper file may be written into the project on first use. To create a trigger, use generate_trigger_code to produce the setup code, add it with manage_script_content, then run it with run_script_function.

Inputs: action (required), script_id (required), user_google_email (required), dev_mode, +3 more. Returns: result

manage_script_versionManage Script VersionA

Create immutable version snapshots of a script project.

Manage task lists: create, update, delete, or clear completed tasks.

Inputs: action (required), user_google_email (required), title, task_list_id. Returns: result

modify_doc_textModify Doc TextA
Destructive

Modifies text in a Google Doc - can insert/replace text and/or apply formatting in a single operation.

TIP: To append text to the end of the document without calculating indices, set end_of_segment=true. This avoids index calculation errors.

HEADING MODE: Pass heading instead of start_index to edit the body below a heading, up to the next heading of equal or shallower level. text is rendered as Markdown and replaces that body; end_of_segment=true appends instead. Formatting parameters without text format the whole body.

For ordinary header/footer text, prefer update_doc_headers_footers. Only pass segment_id when you already have a real header/footer/footnote segment ID from inspect_doc_structure output. Do not guess IDs such as "kix.header" or "kix.footer".

Inputs: document_id (required), user_google_email (required), bold, text, +19 more. Returns: result

modify_gmail_message_labelsModify Gmail Message LabelsA
Destructive

Adds or removes labels from a Gmail message. To archive an email, remove the INBOX label. To delete an email, add the TRASH label.

Inputs: message_id (required), user_google_email (required), add_label_ids, remove_label_ids. Returns: result

modify_sheet_valuesModify Sheet ValuesA
Destructive

Modifies values in a specific range of a Google Sheet - can write, update, or clear values, insert Smart Chips (Drive files/folders or People), or copy another range into it.

Inputs: range_name (required), spreadsheet_id (required), user_google_email (required), chips, +6 more. Returns: result

move_sheet_rowsMove Sheet RowsA
Destructive

Moves rows from one sheet to another within the same spreadsheet. The move is performed in a single batchUpdate (copyPaste followed by deleteDimension). Note: batchUpdate executes requests sequentially but does not roll back on partial failure — if the copy succeeds but the delete fails, rows may be duplicated. Formulas, data types, and formatting are preserved (unlike a values.get/append round-trip). Row numbers are 1-based (matching the spreadsheet UI).

Inputs: end_row (required), start_row (required), source_sheet (required), spreadsheet_id (required), +2 more. Returns: result

query_freebusyQuery FreebusyB
Read-onlyIdempotent

Returns free/busy information for a set of calendars.

resize_sheet_dimensionsResize Sheet DimensionsA
Destructive

Manages sheet-level dimension properties: resize columns/rows, auto-resize to fit content, freeze rows/columns, hide/unhide rows/columns, and insert/delete rows/columns.

Every row number and column letter refers to the sheet as it was before the call, even when one call both inserts and deletes. Deletes are applied before inserts, and an insert position inside a deleted span lands where that span was.

Inputs: spreadsheet_id (required), user_google_email (required), hide_rows, row_sizes, +16 more. Returns: result

run_script_functionRun Script FunctionC
Destructive

Executes a function in a deployed script.

Inputs: script_id (required), function_name (required), user_google_email (required), dev_mode, +2 more. Returns: result

search_contactsSearch ContactsB

Inputs: query (required), user_google_email (required), page_size, page_token, +1 more. Returns: result

search_messagesSearch MessagesA
Read-onlyIdempotent

Searches for messages in Google Chat spaces by text content and/or time range.

Inputs: user_google_email (required), query, space_id, page_size, +2 more. Returns: result

send_gmail_messageSend Gmail MessageA
Destructive

Sends an email using the user's Gmail account. Supports new emails, replies, and forwards, with optional attachments. Supports Gmail's "Send As" feature to send from configured alias addresses.

To forward an existing message, pass forward_message_id. The original subject, body (quoted with a "Forwarded message" header), and attachments are carried over. In forward mode, body (if any) is prepended as a note and subject is optional. Threading, reply, and signature options do not apply when forwarding.

THIS TOOL SENDS IMMEDIATELY AND CANNOT SCHEDULE. Gmail's REST API exposes no send-time parameter; Schedule send is a web-UI feature with no API equivalent, so no argument to this tool can defer delivery. Never tell a user a message was scheduled. For "prepare now, deliver later", create a draft with draft_gmail_message. An external scheduler must retain the message data to create and send a new message via send_gmail_message at the chosen time, or call users.drafts.send with the draft ID returned by draft_gmail_message. Alternatively, let the user schedule that draft in the Gmail UI.

Inputs: user_google_email (required), cc, to, bcc, +15 more. Returns: result

send_messageSend MessageA
Destructive

Sends a message to a Google Chat space, or edits a message already sent there.

Inputs: space_id (required), message_text (required), user_google_email (required), thread_key, +2 more. Returns: result

set_drive_file_permissionsSet Drive File PermissionsA
Destructive

Sets file-level sharing settings and controls link sharing for a Google Drive file or folder.

This is a high-level tool for the most common permission changes. Use this to toggle "anyone with the link" access or configure file-level sharing behavior. For managing individual user/group permissions, use share_drive_file or update_drive_permission instead.

Inputs: file_id (required), user_google_email (required), link_sharing, writers_can_share, +1 more. Returns: result

set_publish_settingsSet Publish SettingsB

Updates the publish settings of a form.

Inputs: form_id (required), user_google_email (required), is_published, is_accepting_responses. Returns: result

start_google_authStart Google AuthA

Manually initiate Google OAuth authentication flow.

NOTE: This is a legacy OAuth 2.0 tool and is disabled when OAuth 2.1 is enabled. The authentication system automatically handles credential checks and prompts for authentication when needed. Only use this tool if:

  1. You need to re-authenticate with different credentials

  2. You want to proactively authenticate before using other tools

  3. The automatic authentication flow failed and you need to retry

In most cases, simply try calling the Google Workspace tool you need - it will automatically handle authentication if required.

Inputs: service_name (required), user_google_email. Returns: result

update_doc_headers_footersUpdate Doc Headers FootersA
Destructive

Safely creates or updates header/footer text in a Google Doc.

This is the default tool for header/footer content. Do NOT use batch_update_doc with create_header_footer just to set header/footer text; that low-level operation is only for advanced section-break workflows and can fail when the default header/footer already exists.

This tool handles both creation and update in one call:

  • If the header/footer does not exist, it is automatically created first.

  • If the header/footer already exists, its content is replaced.

You do NOT need to create a header/footer separately before calling this tool. Simply call it with the desired content and it will work whether the header/footer exists or not.

Inputs: content (required), document_id (required), section_type (required), user_google_email (required), +1 more. Returns: result

update_drive_fileUpdate Drive FileA
Destructive

Updates metadata, properties, and/or content of a Google Drive file.

Providing new content (inline as content, fetched from file_url, or on a local server read from a file path) replaces the file's content in place, preserving the existing file ID, sharing, comments, and links. For native Google Docs/Sheets/Slides the source is uploaded with its source MIME type so the Drive API applies the same format conversion as import_to_google_doc (markdown headings, tables, bold, etc.). For any other file (.md, .txt, .pdf, ...) there is nothing to convert, so the bytes are written back as-is under the file's own MIME type. Metadata and content can be updated in a single call.

mode='append'/'prepend' splice content onto the file's existing text server-side, so only the new text has to be supplied — no need to send the whole file back to rewrite it.

Drive shortcuts are handled according to the kind of update: supported resource-local metadata changes (rename, move, trash, star, description, and custom properties) apply to the supplied shortcut, while content replacement follows the shortcut and updates its target. To avoid applying metadata to the wrong resource, a shortcut call cannot combine content with resource-local metadata. Update the shortcut metadata and target content in separate calls.

Inputs: file_id (required), user_google_email (required), mode, name, +13 more. Returns: result

    B3/5.0

    Scored across 119 tools

    Disambiguation3/5

    The tools are grouped by Google product and most have distinct resource/action targets, but there is meaningful overlap in several areas: Drive permission tools (manage_drive_access vs set_drive_file_permissions), document editing tools (modify_doc_text vs batch_update_doc vs find_and_replace_doc), and paired list/manage comment tools. Detailed descriptions help resolve many cases, but selecting the right tool among 119 still requires careful reading.

    Naming Consistency4/5

    Almost all tools use snake_case with a verb-first pattern (get_, list_, create_, update_, manage_, search_, send_, batch_), which is highly predictable. Minor deviations exist: product prefixes are inconsistent (gmail-specific tools often include gmail, while Docs/Sheets tools usually do not), and consolidated manage_* tools sit alongside specific create_/update_/delete_ tools.

    Tool Count1/5

    119 tools is an extreme mismatch for a usable MCP tool surface. While the server spans many Google Workspace products, this volume forces agents to choose among numerous closely related operations and increases the chance of misselection. The count alone makes the set unwieldy regardless of individual tool quality.

    Completeness4/5

    Coverage is very broad across Gmail, Calendar, Drive, Docs, Sheets, Slides, Chat, Forms, Tasks, Contacts, Apps Script, and Custom Search, with most lifecycle operations represented. There are still minor gaps and stale cross-references: descriptions mention tools like format_text, delete_text, share_drive_file, and update_drive_permission that are not present in the exposed set, and some product-level delete operations are only indirectly available.
