Security Report

5.2
Moderate5.2Moderate Risk

Apple Mail MCP is a well-engineered macOS mail server with thoughtful security patterns. Authentication is not applicable (local-only access to user's own mailbox). The codebase demonstrates strong defensive practices: proper file permission handling (0o600 for cached attachments, 0o700 for cache dirs), careful fallback strategies, input validation, and good error handling. Permissions (file_read, file_write, env_vars, process_spawn) align appropriately with the mail-reading purpose. Minor code quality observations do not impact security posture. Supply chain analysis found 3 known vulnerabilities in dependencies (1 critical, 1 high severity). Package verification found 1 issue.

Security scores are indicators to help you make informed decisions, not guarantees. Always review permissions before connecting any MCP server.

Permissions Required

This plugin requests these system permissions. Most are normal for its category.

File System Read

Reads files on your machine. Normal for tools that analyze or process local data.

File System Write

Writes or modifies files on your machine. Check that this is expected for the tool.

env_vars

Check that this permission is expected for this type of plugin.

process_spawn

Check that this permission is expected for this type of plugin.

How to Install

Add this to your MCP configuration file:

{
  "mcpServers": {
    "io-github-imdinu-apple-mail-mcp": {
      "args": [
        "apple-mail-mcp"
      ],
      "command": "uvx"
    }
  }

Apple Mail MCP

Python 3.11+ License: GPL v3 macOS MCP Code style: ruff CI

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

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.

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
