Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package apple-mail-mcp
Claude Code 
claude mcp add apple-mail-mcp -- uvx apple-mail-mcp==0.5.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "apple-mail-mcp": {
            "command": "uvx",
            "args": [
                "apple-mail-mcp==0.5.0"
            ]
        }
    }

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

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"
    }
  }
}
# 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

ToolPurpose
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
