"A method to allow vision models to process and understand image files" matching MCP servers:

Sends document files (EPUB, PDF, DOCX, etc.) to your Kindle via email using Amazon's Send to Kindle feature.

One-pass agentic inbox triage as an MCP server: fetch unread Gmail → classify (action_needed/fyi/newsletter/noise) → summarize → extract tasks → draft replies as Gmail DRAFTS (never sends) → flag calendar → write a triage report. Four stdio tools (fetch_emails, save_gmail_draft, append_tasks, write_report); the host is the LLM, so it runs keyless in Claude Code. Gmail scopes: readonly + compose

A Model Context Protocol (MCP) server that allows Claude Desktop to send documents directly to your Kindle e-reader.

Enables pushing enriched leads into Instantly or Smartlead campaigns with ICP score gating, deduplication, and dry-run previews via an Apify actor.

An MCP server that sends plain-text Gmail messages only to a predefined allowlist, using generated recipient IDs instead of email addresses to enforce security.

Enables AI agents to inspect any public domain’s web technology stack, email deliverability and DNS health (MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT, BIMI), and HTTPS security posture with typed JSON scores and remediation-ready findings, plus history, bulk checks, monitoring alerts, and reverse technology lookups.

Official MCP server for Shipmail, enabling agents to manage domains, mailboxes, messages, threads, webhooks, and suppressions via natural language.

Enables sending documents (Markdown, PDF, EPUB) directly to a Kindle via Amazon Send-to-Kindle email, with Markdown converted to EPUB using pandoc.

An MCP-compliant server that exposes Gmail and Google Docs as tools, enabling AI agents to draft, send, and manage emails, as well as create, read, and append to documents through natural language.

Enables AI assistants to interact with Microsoft 365 and Office services through the Microsoft Graph API, providing tools for email, calendar, files, Teams, SharePoint, and more with configurable permissions and output formats.

Send email, find out why an email failed, set up sending domains, and manage templates, contacts, lists and campaigns in your AhaSend account.

Enables AI agents to send emails, create drafts in Gmail, and append content to Google Docs via standardized MCP tools.

An MCP server that exposes Google Docs and Gmail capabilities to LLMs via SSE transport.

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

Enables AI agents to read and send email, handle attachments and manage calendar invitations through their own IMAP/SMTP mailboxes, with per-mailbox sender and recipient allow lists and automatic HTML-to-Markdown conversion. It runs as a single self-hosted Docker container, exposing the same tools over MCP and REST.

Read and write email through the Atomic Mail from an AI agent. Handles proof-of-work authentication and JMAP so the agent thinks in JMAP method calls. Use when the user asks to register an email inbox, list mailboxes, fetch or send email.

MCP server for SentVia that provides email infrastructure for AI agents, enabling them to create inboxes, send, reply, forward, search messages, manage drafts, domains, webhooks, and allow/block rules through 21 tools.

Enables MSPs and security teams to manage customer tenants, licenses and usage billing, and to run security operations such as searching events and secured emails, maintaining allow/block exception rules, and quarantining or restoring messages. It is exposed as a stateless, multi-tenant Streamable HTTP endpoint that takes credentials per request via headers.

Enables AI agents to browse email-security incidents and their details, look up what the platform knows about a sender, read mitigation statistics and allow-list entries, and, on explicit request, classify incidents and add or remove allow-list entries through the Management API.

Enables AI agents to search an email security gateway's quarantine, inspect held messages, read sender allow and block lists and mail flow statistics. On explicit request it can also release or delete quarantined messages and add or remove list entries.

Enables an LLM agent to work a FreeScout support inbox without an API key, authenticating through the normal web UI with a pasted browser session cookie or FreeScout username and password. It lets agents read and search conversations, pull ticket and satisfaction reports, add internal notes, save reply drafts, manage tags, close tickets, and optionally forward to an operator allow-list — all under the agent's own mailbox permissions, and never emailing customers.

Exposes Composio tools and actions (Gmail, Linear, etc.) as MCP-compatible tools for language models to interact with in a structured way.

Moves attachments to and from the local disk without their bytes passing through the model's context, and manages several mail accounts under one owner so every write names its account explicitly. Enforces a server-side allow/ask/deny policy where risky writes create a pending action a person must approve in the browser, with no tool able to permanently delete mail.

Enables AI models to send emails, manage contacts, and interact with SendGrid's email platform via MCP.

Enables AI assistants to manage multiple Gmail accounts in a single process through the Model Context Protocol, including cross-account search, reading threads, drafts, sending, labels, and attachments with per-account permission tiers.

Enables AI agents to triage security events, search scanned emails and files, quarantine or restore messages, and manage allow/block exception rules through the Harmony Email & Collaboration API. Runs as a stateless, multi-tenant streamable HTTP endpoint where credentials are supplied per request as headers and never stored.

Enables email-only AI agents to call tools by attaching JSON-RPC 2.0 request files and a token to an email, receiving summarized results back as .result.json files in a threaded reply.

MCP server for Mailprotector — email security management for MSPs, enabling management of customers, domains, users, quarantine, allow/block rules, logs, configuration, and the full long-tail API via a router.

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.

Connects AI assistants to one or more Zoho Mail accounts, enabling read, send, search, reply, and delete operations directly from an AI workflow. Multiple mailboxes can run from a single lightweight process to reduce memory usage.
