MCP Discovery

What is MCP Discovery?

MCP Discovery is a command-line tool written in Rust for discovering and documenting MCP Server capabilities. It displays MCP Server details such as tools, resources, and capabilities directly in the terminal or saves them to files in Markdown, HTML, plain text, JSON, or custom Handlebars templates.

How to use MCP Discovery?

Install the CLI via the project documentation, then run subcommands: print (default) to display capabilities, create to generate a new file, or update to insert capabilities into an existing file between markers. Provide the MCP Server command after --. Example: mcp-discovery -- npx -y @modelcontextprotocol/server-everything.

Key features of MCP Discovery

• Display MCP Server details (tools, resources, capabilities) in the terminal.
• Generate output files in Markdown, HTML, plain text, or JSON.
• Update existing files by inserting capabilities within markers.
• Choose from built-in templates (md, md-plain, html, txt) or supply custom Handlebars templates.
• Automate documentation workflows using the MCP Discovery GitHub Action.

Use cases of MCP Discovery

• Quickly inspect an MCP Server’s capabilities during development.
• Generate or refresh documentation files (README, capabilities pages) automatically.
• Embed up-to-date MCP Server information in CI/CD pipelines via GitHub Action.
• Create custom-styled reports using Handlebars templates for team or client deliverables.
