mcp-mail

mcp-mail is a self-hosted IMAP/SMTP email MCP server that lets Claude, ChatGPT, Cursor and any other MCP client read, search, draft and send email from your existing mailbox, with per-client permissions, an audit log and a one-line install.

curl -fsSL https://raw.githubusercontent.com/Annseraf/mcp-mail/main/install.sh | sudo bash -s -- --auto-update

Local clients (Claude Desktop, Claude Code, Cursor, VS Code) can run it directly: npx -y @annseraf/mcp-mail stdio.

mcp-mail is a maintained continuation of claude-mail-mcp by Markus Stöger (MIT). Existing claude-mail-mcp v0.2 installs can switch with no config changes (compatibility contract).

Works with

AI clients: Claude.ai, Claude Desktop, Claude Code, ChatGPT (developer mode, deep research), Cursor, VS Code, Meta Muse, and any MCP client over Streamable HTTP or stdio. Setup guides: docs/clients.
Mail providers: any IMAP/SMTP mailbox: Fastmail, iCloud, Purelymail, Gmail and Google Workspace (app password), Yahoo, Zoho, Mailbox.org, Migadu, Mailcow, Dovecot/Postfix.
Calendars: any CalDAV server (Fastmail, iCloud, Nextcloud, Radicale), optional.
MCP protocol: 2026-07-28 (stateless) and every earlier revision since 2024-11-05, on the same endpoint.

Other IMAP MCP servers worth a look, depending on your needs: codefuturist/email-mcp (TypeScript, IMAP/SMTP, many tools), tecnologicachile/mail-mcp (Rust, IMAP/SMTP plus Microsoft Graph and EWS) and wildsurfer/your-mail-mcp (read-only, local notmuch index). Check their READMEs for current features.

FAQ

How do I give ChatGPT read-only access to my email?

Run mcp-mail clients add chatgpt --for chatgpt (OAuth login, read-only preset), enable OAUTH=true, and add the server in ChatGPT's developer mode. ChatGPT only ever sees the read tools. See docs/clients/chatgpt.md.

Can I use this with Fastmail, iCloud, Purelymail or Gmail?

Yes. Anything that speaks IMAP and SMTP works. For Gmail, iCloud, Yahoo and Fastmail, create an app password in the provider's security settings and use it instead of your normal password.

How do I stop an AI agent from sending email?

Give the agent a preset without send (read-only, read-draft or organize). The send tool then disappears from its tool list and is rejected if called anyway. For agents that may send, restrict recipients with sendRecipientAllowlist and cap volume with sendRateLimit. See docs/CLIENTS.md.

Can an email trick the AI into doing something?

Emails are untrusted input. mcp-mail wraps every body in untrusted-content delimiters, strips hidden HTML text and tracking pixels, and tells clients to confirm sends and deletions with you. Keep sending off for agents that don't need it. See SECURITY.md.

Does deleting a message lose it forever?

No. delete_message moves the message to Trash. Permanent deletion needs permanent: true and a client with the destructive capability.

Where are my passwords stored?

In accounts.json on your server (optionally encrypted at rest with mcp-mail secrets encrypt). In multi-tenant mode, credentials are envelope-encrypted per tenant with a local key file or OCI Vault. They are never returned by any tool, API or log.

Can my agent sign emails?

Yes. Each account can have a sender display name and a signature, set in accounts.json or by the agent itself with update_account_settings. Pass include_signature: false to send without it.

I'm on claude-mail-mcp. Do I need to change anything?

No. Swap the binary; your .env, accounts.json and connected clients keep working. CI enforces this against recorded v0.2.1 behavior.

Security model

Binds to 127.0.0.1 by default; put nginx or Caddy in front for TLS.
Clients authenticate with OAuth 2.1 (PKCE, rotating refresh tokens), per-client static tokens (stored hashed), or the legacy shared token.
Every tool call is checked against the client's policy twice: when listing tools and when calling them.
The audit log records who did what, never message content.
Mail content is fenced as untrusted; sends and deletions should be confirmed by a human.
Releases are built by CI from tagged commits only, with checksums and provenance attestation.

Details: SECURITY.md, docs/CLIENTS.md, docs/PLATFORM.md.

Configuration

.env: transport settings (.env.example). Everything new is optional.
accounts.json: mailboxes (same format as claude-mail-mcp; optional fromName/signature).
clients.json: per-client identities and policies (docs/CLIENTS.md).
Multi-tenant mode and the admin API: docs/PLATFORM.md.

Upgrading

From claude-mail-mcp v0.2.x: no config changes required. Install mcp-mail pointing at the same .env, accounts.json and (if you use one) OAuth state. New features stay off until you enable them. Two approved behavior changes are listed in docs/COMPATIBILITY.md: deleting moves to Trash, and email content is fenced as untrusted (UNTRUSTED_FENCING=false restores the old output).

Development

npm ci

npm run check # lint, format, typecheck, unit tests, license scan, build npm run test:compat # compatibility gate + integration suites (needs GreenMail, see docs/COMPATIBILITY.md)

Adding a tool: docs/ADDING_A_TOOL.md. Contributions: CONTRIBUTING.md.
