Local serverstdioPython

What is the Mac MCP server?

Professional letterhead PDF generator for macOS with Markdown support and smart margin detection. That is what the mac mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.

The short version

A professional macOS utility that applies letterhead templates to PDF and Markdown documents. Mac-letterhead creates drag-and-drop applications that automatically merge your company letterhead with documents while preserving formatting and ensuring professional presentation.

Getting it running

mac-letterhead on PyPI is all you need. Most clients run it directly, so configuration is a few lines and a restart.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Prerequisites — Mac-letterhead expects your letterhead files to be organized in ~/.letterhead/:

What it needs from you

Configuration is passed through the environment: TWINE_USERNAME, TWINE_PASSWORD. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • macOS: Required for droplet applications and PDF processing - Python: 3.10 or higher - uv package manager: Install with pip install uv if needed

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Mac's toolset — Prerequisites — is a fair guide to whether it matches your workflow. It is maintained by easytocloud; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Frequently asked questions

It connects Mac to MCP-compatible AI assistants such as Claude and Cursor, exposing 1 tool (Prerequisites) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Mac directly.
