How to use Mac Messages MCP?
Install via uvx mac-messages-mcp (requires macOS 11+, Python 3.10+, and the uv package manager). Grant Full Disk Access to your terminal or app. Integrate with Claude Desktop by adding a config with command uvx mac-messages-mcp or with Cursor by pasting uvx mac-messages-mcp in MCP settings. For Docker, use mcp-proxy to bridge stdio to HTTP.

FAQ from Mac Messages MCP
What are the prerequisites for Mac Messages MCP?
macOS 11+, Python 3.10+, the uv package manager, and Full Disk Access permission for the terminal or application running the server.
How do I install Mac Messages MCP?
Run uvx mac-messages-mcp in your terminal, or install from PyPI with uv pip install mac-messages-mcp. For source installation, clone the repo and run uv install -e ..
Does Mac Messages MCP work inside Docker?
Messages.app automation is macOS‑only, so the server itself does not work inside a Linux container. The Dockerfile is for catalog checks and read‑only database experiments with mounted data. To connect from a container, run mcp-proxy on the host to bridge stdio to HTTP.
How are attachments handled?
Attachments use progressive disclosure: message searches show a compact summary, an attachment‑first search returns metadata, and fetching returns the file. Images are returned inline (HEIC converted to PNG), while PDFs, video, and audio return a filesystem path. Inline image bytes are capped at 5MB by default.
What message formats are supported for recipients?
E.164 phone numbers with a leading + (e.g., +14155551234) are most reliable. Bare digit numbers are normalized, and 10‑digit US numbers are sent as +1.... The tool_find_contact returns phone matches in send‑ready format.
