Overview

What is MCP Discovery Action?

MCP Discovery Action is a GitHub Action that runs the MCP Discovery CLI to create, update, or print MCP server capability details in a Markdown or other formatted file. It is built for developers using MCP servers who want to automatically generate documentation of their server’s capabilities.

How to use MCP Discovery Action?

Add the action to a GitHub Actions workflow with the rust-mcp-stack/mcp-discovery-action@v1 step. Required inputs are command (e.g., create, update, or print) and mcp-launch-command (the command to start your MCP server). Optional inputs include filename, template, template-file, template-string, log-level, token, and version. See the README examples for typical workflows.
