inspector

A visual debugger for MCP servers: connect your server, browse its tools and call them by hand. Comes as a web UI, a CLI and a TUI.

Who it is for

For anyone writing an MCP server who wants to test it without wiring up a model.

How to start

  1. Launch the web UI: npx @modelcontextprotocol/inspector.
  2. For scripts and CI use npx @modelcontextprotocol/inspector --cli.
  3. Connect your server and call its tools from the interface.

Steps are taken from the README. Check the current version in the repository before running them.

ChromeDevTools

chrome-devtools-mcp

Hands Chrome DevTools to an agent: network, console, performance, screenshots. The agent does not just click, it sees why a page is slow or broken.

53Kstars+2K in 30 dTypeScript

A Playwright-based MCP server that lets an agent drive a browser through page structure rather than screenshots. Good for testing sites and automating web actions.

GitHub's official MCP server: an agent reads repositories, issues and pull requests and works with them. Comes as a hosted version from GitHub and a local one in Docker.
