Summary

local-manpage-mcp-server is an MCP server that extracts and exposes the man pages of all executables in your $PATH as MCP resources. Its primary goal is to give an LLM (or any MCP client) direct access to up-to-date documentation for the commands installed on the host system. This server is intended to run on Linux distributions only (see Disclaimer below).

The create_all_manpage_files tool generates the manpages/ directory where the extracted man pages are stored. These files are then served when an MCP resource is requested. A wrapper tool is also provided in case your host application does not support MCP resources directly.

Disclaimer

Linux Only: This server is designed exclusively for Linux distributions. It relies on the man and col utilities (and a standard $PATH structure) to extract man pages. It has not been tested on macOS, BSD, or Windows, and may not function correctly on those systems.

Permissions: You must have read access to all directories in your $PATH and write permissions for a local manpages/ folder (created automatically).

Resource Limits: Generating man pages for a large number of binaries can be CPU- and disk-intensive.

Argument Safety: The arguments passed to man and col are not sanitized or validated. This could potentially allow command injection if malicious input is provided.

Setup

git clone https://github.com/yourusername/local-manpage-mcp-server.git
cd local-manpage-mcp-server

python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt

Starting the MCP Server and Inspector

uv run mcp dev server.py

Usage

One goal of this project is to provide a self-explanatory server that exposes usage information as a prompt for your host application. This way, your LLM can describe the workflow automatically.

In addition, you must run the create_all_manpage_files tool to generate the MCP resources based on the commands available on your system. After execution, all relevant man pages should be accessible as MCP resources.
