Apple Mail MCP

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

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.

Tools

Tool	Purpose
list_accounts()	List email accounts
list_mailboxes(account?)	List mailboxes
get_emails(filter?, limit?)	Get emails — all, unread, flagged, today, last_7_days
get_email(message_id)	Get single email with full content + attachments
search(query, scope?, before?, after?, highlight?)	Search — all, subject, sender, body, attachments
get_email_links(message_id)	Extract links from an email
get_email_attachment(message_id, filename)	Extract attachment content
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.

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
