Apple Mail MCP MCP Server

io.github.imdinu/apple-mail-mcp

Full-coverage FTS5 body search for Apple Mail — reliable on large mailboxes.

What is the Apple Mail MCP MCP server?

Apple Mail MCP is an MCP server that provides full-coverage full-text search and email management tools for macOS Apple Mail. It uses FTS5 indexing to reliably search entire mailboxes, including message bodies, without the timeouts and limitations of AppleScript-based alternatives.

Apple Mail MCP gives AI agents access to your Apple Mail through 8 tools for reading, searching, and extracting email content. It's designed for large mailboxes where traditional AppleScript-based servers timeout, offering fast single-email fetches (~3ms), account and mailbox listing, and comprehensive search across subjects, senders, bodies, and attachments.

Tools & capabilities

Tools this server exposes to the agent.

  • list_accounts — List all email accounts configured in Apple Mail
  • list_mailboxes — List mailboxes for a specific account or all accounts
  • get_emails — Retrieve emails with optional filters (all, unread, flagged, today, last_7_days) and limit
  • get_email — Fetch a single email by message ID with full content and attachments
  • search — Search emails across all, subject, sender, body, or attachments with optional date range and highlighting
  • get_email_links — Extract all links from a specific email
  • get_email_attachment — Extract and retrieve attachment content by filename
  • get_attachment — Deprecated tool — use get_email_attachment instead

Use cases

  • Search your entire mailbox for emails by subject, sender, body content, or attachments without timeouts
  • Retrieve and read specific emails with full content and attachment metadata for analysis
  • Extract links and attachments from emails for further processing or archival
  • Filter emails by status (unread, flagged) or date range (today, last 7 days) for quick access
  • Integrate email search and retrieval into AI workflows for tasks like invoice extraction or report finding

Apple Mail MCP MCP server FAQ

What is Apple Mail MCP?

Apple Mail MCP is an MCP server that provides AI agents with full-coverage search and read access to macOS Apple Mail, including body search via FTS5 indexing, reliable on mailboxes with tens of thousands of messages.

Is it free?

Yes, Apple Mail MCP is open-source under GPL-3.0 and free to use.

How do I install it in Claude Desktop?

Download the `.mcpb` bundle from the latest release on GitHub and double-click it, or run `pipx install apple-mail-mcp` and add it to your MCP client config.

Do I need to set up authentication?

No authentication is required. You only need to grant Full Disk Access to Claude Desktop or your MCP client in System Settings so the server can read your mail database.

What platforms does it support?

Apple Mail MCP runs on macOS only (Python 3.11+) and requires access to the local Apple Mail database.

How do I build the search index?

Run `apple-mail-mcp index --verbose` from Terminal (which must have Full Disk Access) to build the FTS5 search index for faster body searches.

The only Apple Mail MCP server with full-coverage body search — reliable on large mailboxes where AppleScript-based servers timeout. 8 tools for reading, searching, and extracting email content.

Read the docs for the full guide.

Quick Start

Claude Code (plugin)

claude plugin marketplace add imdinu/apple-mail-mcp
claude plugin install apple-mail@imdinu

Claude Desktop (one-click bundle)

Download apple-mail-mcp-<version>.mcpb from the latest release and double-click it.

Both the plugin and the bundle run the released PyPI package via a thin launcher (uvx → pipx → private venv, whichever is available) — no vendored code, identical behavior to a manual install. They start the server with --watch; grant Full Disk Access to the launching app (Claude Code / Claude Desktop) so the index stays fresh.

Any MCP client

pipx install apple-mail-mcp

Add to your MCP client:

{
  "mcpServers": {
    "mail": {
      "command": "apple-mail-mcp"
    }
  }
}

Build the Search Index (Recommended)

# Requires Full Disk Access for Terminal
# System Settings → Privacy & Security → Full Disk Access → Add Terminal

apple-mail-mcp index --verbose

Configure (Optional)

apple-mail-mcp init   # writes ~/.apple-mail-mcp/config.toml

Writes a commented config file you can edit to set defaults like your primary account or mailbox. Every key has a matching APPLE_MAIL_* env var if you prefer environment-based config. See Configuration for the full schema and precedence rules.

get_attachment(message_id, filename)Deprecated — use get_email_attachment()

Performance

Tested against 6 other Apple Mail MCP servers on a real ~73K-message mailbox:

  • Only server with full-coverage body search. Most competitors don't support body search at all; the one that does (BastianZim) live-scans only the 5000 most recent messages — silent miss on anything older. Our FTS5 index covers the entire mailbox.
  • ~3ms single email fetch via disk-first .emlx reading (no JXA round-trip).
  • ~1ms list_accounts and ~5ms 50-email listing via direct Envelope-Index SQLite reads (0.4+) — same path BastianZim/rusty/pl-lyfx use, with JXA as the correctness fallback.
  • ~7ms subject search via FTS5 — competitive with native Rust on the same operation.
  • Reliable across all 6 benchmarked operations on a 73K mailbox; AppleScript-based servers timeout, throw syntax errors, or skip operations they don't support.

Capability Matrix

Configuration

Apple Mail MCP works out of the box. To customize defaults, run apple-mail-mcp init to generate a config.toml template — or use the matching APPLE_MAIL_* environment variables. See the Configuration docs for the full schema and the CLI > env > file > default precedence.

Per-client env overrides via the MCP client's launch config also work:

{
  "mcpServers": {
    "mail": {
      "command": "apple-mail-mcp",
      "args": ["--watch"],
      "env": {
        "APPLE_MAIL_DEFAULT_ACCOUNT": "Work"
      }
    }
  }
}

CLI Usage

All tools are also available as standalone CLI commands (no MCP server needed):

apple-mail-mcp search "quarterly report" --scope subject
apple-mail-mcp search "invoice" --after 2026-01-01 --limit 10
apple-mail-mcp read 12345
apple-mail-mcp emails --filter unread --limit 10
apple-mail-mcp accounts
apple-mail-mcp mailboxes --account Work
apple-mail-mcp extract 12345 invoice.pdf

All commands output JSON. Generate a Claude Code skill for CLI-based access:

apple-mail-mcp integrate claude > ~/.claude/skills/apple-mail.md
