Mac messages MCP: MCP server, setup and security

What Mac messages MCP does

According to its repository: “Query, analyze, send and receive iMessage conversations, with phone number validation, attachments, contacts and group chats.”

An MCP server gives an AI agent extra tools it calls during the conversation: the agent reads their description, decides to use them and gets the result back. Mac messages MCP is listed under Messaging and email, a category of 107 servers in the directory, where it ranks #17 by stars.

Topics declared by the repository: applescript, claude, contacts, cursor, imessage, mac.

Installing and connecting Mac messages MCP

No package or remote server is declared in the official MCP registry: you install it from source, following the repository README.

Like any MCP server, you declare it in your client's configuration (Claude Desktop, Claude Code, Cursor, VS Code, Codex…): a name, the command that starts it or its URL, and any environment variables. The client then starts it and lists its tools. Project language: Python. Listed systems: macOS.

Security: what to check

An MCP server runs code with the rights you give it, and the model reads its tool descriptions: a malicious or compromised server can hijack the agent. Read the code, or pick a maintained and widely used server, before connecting it.

None of the risk signals we track (system access, secrets, missing licence, abandonment) applies to Mac messages MCP. That does not replace reading the code.

Good practice: grant only the rights needed (least privilege), require human approval for irreversible actions, and run the AI agent security check.

Project activity and maintenance

Created on March 13, 2025, the carterlasalle/mac_messages_mcp repository has 335 stars and 53 forks, with 1 open issues. It has more stars than 84% of the servers in the directory. It received changes this month.

Stars measure attention, not quality: a recent, heavily promoted project can collect them fast, while a useful but niche server will have few.
