Documentation Overview
mail-mcp
MCP server that gives Claude (and other MCP hosts) full access to Mail.app on macOS — search, read, send, reply, flag, move, and more — across every account configured in Mail.app (iCloud, Exchange, IMAP, etc.).
Prerequisites
- macOS (Mail.app required)
- Node.js 20+
- An MCP host: Claude Desktop, Amazon Quick, or any stdio MCP client
Installation
Claude Desktop — one-click install (recommended)
- Download
mail-mcp.mcpbfrom the latest release - Double-click the
.mcpbfile — Claude Desktop installs it automatically - Grant the required macOS permissions (see below)
Manual / Amazon Quick / other hosts
Or install globally:
Point your MCP host at the mail-mcp binary (stdio transport). Example config:
Required macOS permissions
Grant these to the application that runs the MCP host (Claude Desktop, Amazon Quick, etc.):
| Permission | Where to grant |
|---|---|
| Full Disk Access | System Settings → Privacy & Security → Full Disk Access |
| Automation → Mail | System Settings → Privacy & Security → Automation |
The MCP server process inherits permissions from the host application that launches it.

How it works
- Search & read — queries Mail's own Envelope Index SQLite database directly for fast, structured results across all accounts
- Actions (send, reply, flag, move, trash) — driven by AppleScript automation against Mail.app, so they work even for accounts where messages aren't stored as local files
Development
Interactive MCP testing:
Privacy Policy
mail-mcp is a local MCP server that runs entirely on your Mac. It has no backend, no telemetry, and makes no network requests of its own.
What it accesses:
- Mail.app's Envelope Index database (
~/Library/Mail/) — read-only, used for search queries - Mail.app via AppleScript — to read message bodies, send mail, flag, move, and trash messages
What it does NOT do:
- Collect, store, or transmit any data outside your Mac
- Connect to any external server or API
- Log message content anywhere
All email data stays on your device and is only passed to the MCP host (Claude Desktop or another client) as part of normal tool responses. You control exactly which tools Claude can invoke.
