"Understanding Proxies or Proxy Servers" matching MCP servers:

Enables Claude Code to search, retrieve, and draft email replies using real Microsoft 365 inbox context, with executive-style profiles and one-click publishing.

Enables Claude.ai and other MCP clients to access a personal Outlook.com account's mail and calendar through Microsoft Graph after a standard OAuth 2.0 sign-in, with no stored tokens or pre-generated credentials. Supports searching, reading, sending, drafting, organizing, and moving messages plus read-only calendar browsing, with optional read-only aliases that restrict an account to view-only scopes.

Give AI agents their own email inboxes. Create, send, receive, and manage email entirely via MCP tools.

A remote MCP server that proxies tool calls to the caller's own Composio account, using their own API key for each request to access services like Gmail, Slack, and Google Sheets.

MCP server that enables AI agents to check if email addresses or domains are disposable using the isitdisposable.com API. It provides tools like check_email, check_domain, and check_batch for real-time validation.

Enables managing multiple Gmail accounts under one OAuth client, with per-account access levels, cross-account search, and read/write operations via stdio or Streamable HTTP.

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

Reads and searches local email archives (.mbox or .eml) with full MIME parsing, enabling queries about senders, subjects, dates, and bodies while keeping all data on your machine.

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.

An email MCP server that lets Claude or any MCP client search, read and draft mail via IMAP, treating every message as untrusted input. It prioritizes safety with plain-text-only bodies, disabled sending until an allowlist is set, and no bcc support.

Enables AI agents to verify email addresses and receive a 'send', 'hold', or 'kill' verdict with the reason, while also managing signup and credits programmatically.

Diagnoses a domain's email authentication — SPF, DMARC, DKIM, MX, blacklists and domain or SSL expiry - and returns copy-paste fix records generated by a validating engine, never a language model. The MCP server is hosted remotely; this repository carries the plugin manifest, connector config and bundled skill.

Gives an AI assistant read- and draft-only access to a single personal Microsoft mailbox, letting it search, list and read mail, browse folders, save attachments to a jailed directory, and create new or reply drafts. It requests no send scope, so mail can never be sent, deleted, moved or marked, and calendar, contacts and files are untouched.

Enables agents to validate and normalize phone numbers, email addresses, and postal addresses with production-grade, country-specific rules, including formatting, typo detection, and checks for disposable domains or fictional numbers.

An MCP server for Microsoft Graph, exposing 60 tools across calendar, email, meetings, Teams chat, files, people, directory, tasks, and OneNote over stdio or Streamable HTTP.

Baryon connects MCP-compatible AI assistants to Proton Mail through a local bridge, enabling email search, reading, attachment handling, and draft creation while enforcing deliberate permission limits. It runs locally and cannot send, delete, or modify mail.

Hosted email MCP server for AI agents. Connect Gmail or any IMAP/SMTP mailbox (Fastmail, iCloud, Yahoo, Zoho, Yandex) to Claude, ChatGPT, Cursor and any MCP client to read, search, send, organize, schedule and auto-triage email. Mail is fetched live and never stored.

Enables connecting and searching multiple Gmail or Google Workspace accounts via friendly aliases, with read-only access and source mailbox attribution for each result.

Your mailboxes in ChatGPT and Claude: Gmail, iCloud, Fastmail or any IMAP/SMTP account, as many as you like. Search, read, threaded replies, drafts, allowlisted sending and attachments; passwords are encrypted in the browser and the server stores nothing.

A Gmail MCP server that enables Claude to send, search, and read emails using either Gmail API or SMTP/IMAP backend.
