An MCP server that provides Unix command documentation directly within Claude conversations. It retrieves help pages, man pages, and usage information for Unix commands, lists available commands categorized by function, and checks if a specific command exists along with its version.

How to use Unix Manual Server (MCP)?

Install Python 3.13+, clone the repository, and run pip install -e . or uv install -e .. Then install the server in Claude Desktop with mcp install unix_manual_server.py.

FAQ from Unix Manual Server (MCP)

What are the prerequisites for using Unix Manual Server (MCP)?

Python 3.13 or later and Claude Desktop (or any MCP‑compatible client) are required.

How does the server prevent command injection?

It validates command names against a regex pattern, executes commands directly without a shell, and sets timeouts on all executions. It only checks for documentation, never runs arbitrary commands.

Where does the documentation come from?

The server uses the local system’s man pages and command information — no external data sources are involved.

How do I install the server for development or testing?

Clone the repository, install the package (pip install -e . or uv install -e .), then use mcp dev unix_manual_server.py to test locally without installing in Claude Desktop.

Does the server produce any logs?

Yes, logs are saved to unix-manual-server.log in the same directory as the script, which is useful for debugging.
