imessage-mcp

A read-only MCP server that exposes your iMessage data to Claude Code and Claude Desktop, with automatic contact name resolution.

Setup

1. Install

cd ~/workspace/imessage-mcp
python3.12 -m venv .venv
source .venv/bin/activate
pip install -e .

2. Grant Full Disk Access

The server needs to read ~/Library/Messages/chat.db and the Contacts database. Grant Full Disk Access to the app that runs the server:

1. Open System Settings → Privacy & Security → Full Disk Access
2. For Claude Code: add your terminal app (e.g., Terminal, iTerm2, Ghostty)
3. For Claude Desktop: add the Claude app

3. Configure Claude Code

Add to ~/.claude/settings.json:

{
  "mcpServers": {
    "imessage": {
      "command": "/Users/jaredmoskowitz/workspace/imessage-mcp/.venv/bin/python",
      "args": ["-m", "imessage_mcp"]
    }
  }
}

4. Configure Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "imessage": {
      "command": "/Users/jaredmoskowitz/workspace/imessage-mcp/.venv/bin/python",
      "args": ["-m", "imessage_mcp"]
    }
  }
