"Understanding Boss Mode" matching MCP servers:

Enables Claude Desktop on Windows to search and read Yahoo Mail messages in read-only mode, without sending, deleting, or otherwise modifying them.

An MCP server that exposes a local notmuch email database to an LLM client such as Claude. It is read-first: searching, reading, and understanding mail is always available; writing anything (drafts, tags, exported files) requires an explicit opt-in flag and is confined to clearly bounded locations.

Enables sending emails and listing sent emails with delivery status and open/click counts via the Maillog API.

Enables an assistant to send email and list sent emails through the Maillog email API.

Enables AI agents to read a Proton Mail mailbox through a local Proton Bridge instance, listing folders, browsing recent messages, running full-text searches, and reading individual messages with decoded bodies and attachment info. All access is read-only — mailboxes are opened in IMAP READONLY mode, so nothing is ever modified, and the capability model lets operators opt into future draft, organize, send, and delete tools behind explicit confirmations.

MCP server that gives AI agents the ability to send, read, and search email via Gmail.

Lets Claude connect to a Yahoo Mail account with an app password to read messages, create and manage folders, move messages, and compose or send email, with an optional read-only mode.

Enables sending transactional email and monitoring delivery via the Postmark API, with tools for email, templates, bounces, messages, stats, and suppressions, including a read-only mode.

Enables AI assistants to read, search, organize, and send email in a Viettel mailbox using built-in IMAP/SMTP server settings and encrypted credential storage. Supports optional read-only mode or a custom allowlist to restrict which mailbox tools an assistant can use.

Enables Claude, Codex and other MCP clients to browse folders, search, read, send, reply to, forward, move, flag and delete Microsoft 365 / Outlook.com mail through the Microsoft Graph API, including attachment downloads, newsletter unsubscribe and inbox rules. Signs in with the OAuth device code flow and keeps the refresh token in the OS keychain, with an optional read-only mode that removes every mutating tool.

Enables managing lists, subscribers, campaigns, templates, bounces and transactional email on a self-hosted Listmonk instance through Claude tools, with an optional read-only mode that limits access to read operations.

Enables AI agents to search, read, summarize, label, draft and reply to Naver Mail through Gmail MCP-compatible tools and search syntax, over IMAP/SMTP with EUC-KR-safe decoding. Runs as a remote Streamable HTTP + OAuth server on Cloudflare Workers plus a local stdio mode, so both cloud-hosted and desktop agents can connect.

Enables an AI agent to discover and call bounded Microsoft 365 tools for reading calendar, mail, Teams channels, SharePoint, and Power Platform metadata through MCP, with synthetic fixtures by default and optional Microsoft Entra/Graph tenant integration.

Enables AI assistants to manage a self-hosted Listmonk instance, covering subscribers, lists, campaigns, templates, bounces, system diagnostics, and transactional email sending. Ships with an optional read-only mode that registers only the read tools.

Connects AI assistants to Masaryk University's information system in read-only mode, letting students ask about their timetable, deadlines, emails, grades, and study materials in natural language.

Enables Claude and other MCP clients to manage an addy.io account through the full addy.io API, covering alias creation and bulk actions, recipients, usernames, custom domains, labels, rules, the blocklist and failed deliveries. Runs locally with your own API key, with an optional read-only mode that hides every tool that can change the account.

A production-style MCP server exposing six business tools (web search, database, CRM, email, calendar, analytics) to AI clients via a secure, authenticated interface, with mock mode and a reference agent client.

Enables Claude and other AI agents to read and write Outlook Mail, Calendar, SharePoint, OneDrive, Contacts, OneNote, and Teams content through Microsoft Graph using per-user delegated OAuth, with deny lists, read-only switches, and enforced draft mode for administrative control.

Enables MCP clients to work with ordinary email accounts over IMAP and SMTP — listing mailboxes, searching and reading messages, managing flags, folders, attachments and drafts, and sending, replying or forwarding mail. Supports multiple accounts and providers with per-account safety controls such as read-only mode, send/delete restrictions, recipient allow-lists and rate limits.

Enables AI clients to explore a QQ Mail mailbox over IMAP without ever modifying it, listing accounts and folders, checking mailbox status, searching messages across folders or accounts, and fetching message bodies, threads, and attachments. All access uses read-only mailbox mode, so unread mail stays unread and no sending, deleting, moving, or flag changes are possible.

Enables managing Gmail messages and threads via archive, label, search, trash, and other operations.

Enables natural-language interaction with Gmail, including reading, searching, drafting, and managing emails, with safety features like read-only mode and bounded reads.

A safe, redacting MCP server for Apple Mail on macOS that enables an LLM to read, search, triage, draft, and confirm sending email while stripping secrets and blocking dangerous actions.

A local server that lets Claude Desktop or Claude Code read, search, triage and draft messages, view and add calendar events, and look up or create contacts, all signing in with a single Apple app-specific password. It defaults to drafting rather than sending and offers a read-only mode, plus recipient allowlists, so nothing changes or leaves your account unless you explicitly allow it.

Enables an assistant to search and read mail across multiple Gmail accounts, create drafts in the correct account and thread, apply labels, archive or mark read reversibly, and view events from every calendar in read-only mode. Sending and deleting are deliberately not exposed, so all outgoing mail is reviewed and sent by the user.

Enables authenticated interaction with Microsoft 365 and Office services through the Graph API, covering email, calendar, files, Teams, SharePoint, and more. Supports read-only mode, tool filtering, presets, and multiple cloud environments for safe, controlled access.

An MCP server that reads, searches, organizes, and deletes Proton Mail through the local Proton Mail Bridge, with read-only mode and sender authentication checks. It cannot send mail.

Enables AI clients to read, search, send and triage Microsoft 365 mail, manage folders, attachments and drafts, and work with calendar events and contacts by calling the same internal API the Outlook web app uses, with no Graph app registration or admin consent. Supports Azure CLI token refresh, a read-only mode, and compact normalized JSON output.

Enables LLMs to access candidate information including resume, LinkedIn, GitHub, and contact via email.

Unifies fast on-disk read and search with complete AppleScript writes, behind a mandatory safety layer with read-only mode, batch caps, dry-run, and undo for reversible operations.

Enables AI agents to read, search, download attachments from, send, move, flag, and delete messages and folders in academic mailboxes over IMAP and SMTP, with support for multiple configured accounts. Every write action is gated by a two-step user-confirmation token, and a read-only mode can expose just the reading tools.

A lightweight MCP server providing AI agents a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, with code-enforced restrictions preventing external access or sending.

A security-first MCP server that provides AI agents with a scoped, read-and-draft-only view into Proton Mail via Proton Bridge, ensuring no emails can be sent and access is restricted to configured workspaces.

Provides MCP tools for searching, reading, and drafting Gmail emails, as well as querying SAP OData endpoints with safe read operations and mock mode.
