Basin MCP

What is Basin MCP?

Basin MCP is a reliability MCP tool designed for AI code editors like Cursor and Windsurf. Its primary function is to stop code generation hallucinations by extensively testing your copilot’s output and feeding the test results back to the copilot for automatic improvement. This ensures that your code editor generates reliable, quality code, allowing users to create applications without the fear of AI-generated bugs or inconsistencies. Basin MCP instantly identifies and flags problems, enabling faster and more confident ‘vibe coding’.

How to use Basin MCP?

To use Basin MCP, you can add it to your editor in one of two ways: either by adding a specific configuration to your `mcp_config.json` file with your API key, or by using your editor’s MCP settings dialog to add the line `env BASIN_API_KEY= npx -y basin-mcp@latest`. Before first use, you must install Playwright by running `npm i -g playwright@latest`, as Basin relies on it for testing. To trigger the Basin MCP tool, append the blurb ‘Generate …, and test with Basin MCP tool, server is running at http://localhost:3000’ to the end of your prompt. Basin requires a running server with the code changes to test.
