Turn an AI tool into your smart email engine

Interact with Mailgun API.

Free disposable email for AI—check any @mailinator.com inbox, retrieve messages in multiple formats, and extract verification codes for automated workflows.

Most email MCP servers only read from IMAP. mail-mcp does everything: 30 tools for reading, searching, sending, replying, forwarding, and bulk operations across IMAP, SMTP, Microsoft Graph API, and Exchange Web Services. Multi-account, native OAuth2, built in Rust. Works with Gmail, Microsoft 365, Hotmail/Outlook.com, Zoho, and any standard IMAP/SMTP server.

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. Self-hosted or hosted free tier; passwords are encrypted in the browser and the server stores nothing.

Let AI agents search and read your mail: on-premises Microsoft Exchange (EWS, no cloud API) and any IMAP mailbox with password sign-in, 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.

Strictly read-only mail for agents: ordered filter rules archive matching messages from any IMAP mailbox or the Gmail API to disk as .eml plus markdown, served back over MCP.

Mailows gives AI agents their own real email inboxes, so they can read and send mail via MCP or API without getting the keys to yours.

Verify email addresses in real time, without sending anything: deliverability status and score, disposable, role-based and catch-all detection, typo fixes. Remote server, hosted in France.

Hosted MCP connector for the mailbox you already have. Connect IMAP with an app password, paste one URL and key into your AI client. Sends need confirm.

MCP server for structured, read-only email access. Exposes a minimal, auditable API surface — AI agents can search and read emails, but cannot send, delete, or modify your mailbox.

Integrates with Mailtrap Email API.

Native Gmail MCP server for inbox triage — search with re-verified results, labels, archive/trash, mailbox-side snooze, triage digest, RFC 8058 unsubscribe; no send tools by design.

Send app email and answer replies on the same domains from your agent: list, read and reply to threads across every connected domain, plus send_email. API key auth.

Webinar intelligence for Zoom Meeting-based webinars: Query funnels, registrations, transcripts, and email engagement with 16 tools via OAuth 2.1

Your AI agent for real-world introductions. Create your profile through your AI and join the waitlist. Introductions are coming later. OAuth sign-in required.

Free meeting place for AI agents: register, search the directory, like, and accept intros. Remote streamable-HTTP MCP server; start_here, register and search need no key.

Remote MCP server for MatrixAgentNet, a public network where AI agents publish work, review each other and build a visible track record. Reads, feeds, search, profiles and model stats work without auth; publishing, reviewing and voting need an agent API key per call. Early network: most activity is labeled demo data.

Manage Max AI agents for WhatsApp and Instagram from Claude: rules, knowledge, escalations, integrations and chats, published when you confirm.

Client mail IA avec MCP. Connecte Claude, ChatGPT ou Cursor à ta boîte mail via OAuth pour lire, organiser et répondre aux emails.

An MCP service for device communication and PWM control via the MQTT protocol.

Your IMAP mailbox as an MCP server: list accounts and folders, search and read mail, attachments, drafts. Write tools only where the mailbox owner allows them, and email is sent only after the owner approves it. OAuth 2.1, hosted at mcp4mail.online, open source (MIT) and self-hostable.
