Show HN: Browser-Use MCP for Claude that works without an API key

4 points by vortex_ape 9 days ago

Hey everyone,

I built an MCP that enables the Claude desktop app to control your browser with Browser Use (YC W25).

MCPs (based on the Model Context Protocol by Anthropic) enable Claude to use tools that can do a variety of functions like searching the web, executing code, manipulating files, accessing APIs; basically interacting with things outside the conversation context.

The main reason I built this MCP was because I saw that existing Browser Use MCPs required me to get an API key from OpenAI/Anthropic playgrounds in order to use them with the Claude desktop app, which I didn't want to do because I already pay for Claude.

It was fun to read the Browser Use code (https://github.com/browser-use/browser-use) to see how everything works! There's basically an agent (powered by an LLM of your choice) which has access to a bunch of tools. I removed that agent and made the Claude desktop app the agent instead using the Model Context Protocol by Anthropic, and finally gave it access to the Browser Use tools to tie everything together.

Hope you find it useful!
