imessage-mcp
macOS-only MCP server that exposes iMessage history to Claude and exports per-chat conversations into an Obsidian vault. Mirrors the whatsapp-mcp pattern: same hook, same launchd cadence, same vault shape.
Architecture
- Direct read of
~/Library/Messages/chat.db (SQLite, opened mode=ro&immutable=1). No bridge daemon.
- Voice-note transcription via Whisper local-cpp (reuses the model already installed for whatsapp-mcp).
- FTS5 incremental search index at
~/.claude/imessage-mcp/search.db.
- Vault export per chat into
🤖 AI Chats/iMessage/<Contact>.md and 🤖 AI Chats/iMessage/Groups/<Group>.md.
- Send pathway via AppleScript with draft+confirm pattern (no auto-send).
Tool surface
Read: healthcheck, list_chats, list_messages, get_chat, search_contacts, search_messages, get_message_context, get_unread, get_thread, list_attachments, mark_chat_read, export_to_vault.
Write: send_message (drafts an AppleScript send), confirm_send (commits).
Install
Open Claude Code, paste:
/plugin marketplace add adelaidasofia/imessage-mcp
/plugin install imessage-mcp@imessage-mcp
Then grant Full Disk Access to Claude.app (required for chat.db read) and restart Claude Code. Full setup details and env vars in SETUP.md.
Legacy install (manual .mcp.json registration)
See SETUP.md. The short version: grant Full Disk Access to Claude.app, run uv sync, register in vault .mcp.json, restart Claude Code.

Telemetry
This plugin sends a single anonymous install signal to myceliumai.co the first time it loads in a Claude Code session on a given machine.
What is sent:
- Plugin name (e.g.
slack-mcp)
- Plugin version (e.g.
0.1.0)
What is NOT sent:
- No user identifiers, names, emails, tokens, or API keys
- No file paths, message content, or anything from your work
- No IP address is stored after dedup processing
Why: Helps the maintainer know which plugins people actually install, so attention goes to the ones that get used.
