"A map or mapping service" matching MCP servers:

Provider-agnostic email MCP server that connects any IMAP mailbox to AI assistants, enabling email management through natural language.

A mail service that connects private domain email to MCP clients, enabling sending (with auto signature), receiving, and reading emails through natural language via stdio or SSE transport.

A stdio MCP server exposing a validate_emails tool that lets agents screen email lists without sending mail or probing SMTP, checking syntax, DNS/MX records, disposable domains, role accounts, free providers, typo suggestions, and SPF/DMARC. Each address comes back with a valid/risky/invalid/unknown verdict plus machine-readable reason codes so agents can clean leads and signups before outreach or import.

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.

MCP server that sends mail over SMTP, gated behind an allowlist and a human confirmation

A brain for your mail: MailFathom turns IMAP mailboxes into a self-hosted, AI-native service.

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 verification of email address lists through a chosen third-party service (ZeroBounce, NeverBounce, MillionVerifier, BounceBan, or Reoon), returning one normalized row per address with verdict and role, free, and disposable flags. It protects credits by skipping malformed or duplicate addresses and stopping runs on invalid keys or exhausted balances.

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

Let AI agents search and read your mail: on-premises Microsoft Exchange (EWS, no cloud API or admin setup) and any IMAP mailbox, tested on Mail.ru and Gmail. Text inside PDF, Office and ZIP attachments is searchable in Russian and English. Runs from a local copy, and read-only is enforced at the protocol level.

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.

Enables checking lead rows, CSV files, or Apify datasets for duplicates, email syntax and risk signals, domain issues, missing fields, and stale dates, returning a per-row import, review, or reject verdict so only clean records reach a CRM or sequencer.

Enables AI assistants to verify email deliverability and find business emails via the Verifox API, supporting single and bulk operations.

An MCP server that exposes a verify_email tool for checking email syntax, disposable domains, and MX records, returning a structured validity result.

Enables AI assistants to interact with Fastmail services, providing tools for comprehensive email management, contact searching, and calendar event coordination via the JMAP API. It supports advanced features like threaded conversations, attachment handling, and bulk mailbox operations through natural language.

Enables MCP clients to read, search, organise, and manage IMAP mailbox messages, including saving attachments and drafting replies, while treating mail content as untrusted and keeping write capabilities opt-in.

Giggal.ai is an email verification tool that runs a deep mailbox existence check on every address and verifies catch-all/accept-all and even SEG protected emails. Your bounce rate stays under 5%, and the 30% of every B2B list that other tools flag as "Risky" becomes deliverable again.

Enables AI assistants to search and read institutional IMAP mailboxes, download attachments, mark messages read or unread, move them between folders, and save drafts, all safely by UID. Runs locally over stdio or as a remote HTTP/SSE endpoint secured by a bearer token for clients like ChatGPT and n8n.

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.

Read-only MCP server that connects to multiple IMAP accounts, enabling cross-account email listing, search, and retrieval without modifying mailboxes.

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.

Enables AI assistants to search, read, draft, and send Gmail messages, as well as manage labels and trash using natural language.

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.

Enables AI agents to list, read and download the files attached to Gmail messages, extracting text from PDFs, Word, Excel, PowerPoint and plain-text files straight into context or saving them to disk. It runs locally with read-only Gmail access, so attachments can be summarised, checked or analysed without leaving the chat.

Enables AI assistants to manage multiple Outlook/Microsoft 365 mailboxes simultaneously through MCP tools, with local OAuth token storage.

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

Enables AI assistants to search, read, compose, and manage Thunderbird mail, filters, contacts, and calendar events through the Model Context Protocol.

Enables AI agents to publish static sites and build folders as live websites, push updates, provision and manage custom domains with DNS, and send transactional email. Ships as a local pip/uvx server that reads build folders directly, or as a hosted HTTP endpoint for Claude Code, Claude Desktop, and other MCP clients.

A minimal MCP server for sending plain-text emails and managing Gmail user labels over stdio, using only gmail.send and gmail.labels OAuth scopes.

Enables an AI assistant to list, search, and read email over IMAP without marking messages as read, and to create and revise reply drafts that you review before sending. It runs with least privilege, keeping the app password in an OS keychain or password store and never sending, deleting, or moving anything.
