Yes. The free plan gives you unlimited connected inboxes, unlimited MCP tool calls and unlimited API keys — no daily caps, no card required. The only limit is a per-minute fair-use ceiling to protect the platform. Paid plans add team members, higher burst limits and support, never more usage.

Yes. MCP Emails is open source under AGPL-3.0, and the hosted service runs the same server you can run yourself. A docker-compose stack gets the full MCP server and all its tools running against your own database in about five minutes, for any IMAP or SMTP mailbox. Gmail and Outlook one-click OAuth and the dashboard stay on the hosted plan.

Give your AI
agent an inbox.

Connect Gmail, iCloud, Fastmail, or any IMAP inbox once. Paste one MCP endpoint URL into Claude, Cursor, VS Code, ChatGPT, Windsurf, n8n, Make, or any MCP client. OAuth clients connect in a click, no API key setup. Your agent reads, searches, and sends mail live, and the mail it reads is never stored.

Principles

Six things we believe
about email and agents.

The decisions that shaped the product. If any of them stop being true, that's a bug worth filing.

01Scope
Ten focused tools. The essentials, covered.
Tools cover the everyday work — inbox_list, email_read (list, read, search) and email_compose (send, reply) — plus focused tools for organizing, deleting, folders, drafts, scheduling, contacts, and signatures. Paste the MCP endpoint URL into claude.ai, Claude Desktop, Cursor, or any MCP-compatible agent.
02Storage
Email is fetched live. Never stored.
Every tool call hits your provider in real time: Gmail API, Fastmail JMAP, or IMAP. Message bodies, subjects, and attachments go to the agent and are discarded immediately. We persist one thing per inbox, an encrypted token or app password, so we can make the next call. The one exception is a message you schedule to send later: we hold it until the send time, then keep a record for your history.
03Sending
Sending goes through your provider.
When your agent calls email_compose (to send or reply), the message is dispatched via the Gmail API, Fastmail JMAP, or your own SMTP server. Your domain reputation and deliverability stay entirely in your hands. We never relay mail from our own domain.
04Providers
Gmail, iCloud, Fastmail & any IMAP inbox.
OAuth 2.0 for Gmail; app-specific passwords for Fastmail, iCloud, Yahoo, Zoho, and Yandex; a generic IMAP / SMTP connector for everything else. Connect multiple inboxes, label them by use case (work-gmail, ops-fastmail, support-imap), and scope each API key to the inboxes you want that agent to reach. Teams and agencies can manage every client inbox in one shared workspace with roles and an audit log.
05Access
OAuth 2.0 for agents. One click to revoke.
We're standard MCP (streamable-http) with OAuth 2.1, DCR & PKCE — no vendor lock-in. Works with Claude, Cursor, VS Code, ChatGPT, Windsurf, n8n, Make, LibreChat, OpenWebUI, and any MCP-compatible client. OAuth clients connect automatically via authorization code + PKCE; a scoped API key covers clients without OAuth and scripted access. Revoke any connection from the dashboard in one click.
06Security
Credentials are encrypted at rest.
OAuth tokens and app passwords are AES-256-GCM encrypted before being written to the database. Decryption happens only inside an isolated Edge Function at call time. The encryption key is stored as an environment secret, separate from the database.

How it works

You're the user. We're the pipe.

Three steps from sign-up to your agent reading and sending mail.

Connect your inbox

Sign in and click Connect Inbox. Choose Gmail, iCloud, Fastmail, or any IMAP inbox, then complete OAuth or paste an app password. Credentials are encrypted; the mail your agent reads is never stored.

Paste the URL: OAuth or API key

For an MCP client that supports OAuth 2.0 (claude.ai, Claude Desktop, Cursor, and others), paste https://mcpemails.com/api/mcp, click Connect, and authorize. No key needed. For clients without OAuth (Cline, JetBrains, custom scripts), generate a scoped API key in the dashboard instead.

Your agent works the inbox

The agent calls tools like email_read() or email_compose(). MCPEmails fetches live from your provider and returns the result. Nothing is cached between calls.

inbox_list()

Discover all connected inboxes and their IDs. Call this first, no UUID copy-pasting from the dashboard.

email_read()

Read mail: list recent summaries, fetch a full message by ID, batch-read up to 50, or run a provider-agnostic search — all via the action argument.

email_organize()

Organize mail: move, copy, delete, flag, or archive — one at a time, in bulk, or straight from a search.

email_compose()

Compose: send a new message, reply in-thread, or forward. Dispatched through Gmail API, Fastmail JMAP, or SMTP: your domain, your deliverability.

folder()

Manage folders (labels on Gmail): list, create, rename, or delete, and use them as move destinations.

draft()

Drafts: list, create, update, and send drafts stored in the provider's Drafts folder.

schedule()

Schedule a message for a future time, list pending scheduled sends, and cancel them before they go out.

contact_search()

Find people by name or email with a live scan of recent matching mail. Nothing is stored.

Real prompts

Just ask.
It reads, writes, and files.

No dashboards to learn. Tell your AI assistant what you want in plain English, and it uses mcpemails to get it done.

email_read()

Found it — pulled straight from Alex’s message on Tuesday.

email_read()

“I wanted my agents to work my inbox, but every option meant handing a third party a copy of my email. So I built the pipe I wished existed: connect once, your inbox is fetched live and never stored, and you can cut off any agent in a click. That's the product I trust with my own inbox.”
