Overview

What is Mcp Api Tester?

Mcp Api Tester is an MCP server that tests arbitrary HTTP APIs and automatically generates TypeScript type definitions from the responses. It is built for developers using MCP clients to quickly inspect and type-check API endpoints.

How to use Mcp Api Tester?

Install globally or locally via npm, then run the mcp-api-tester command (or use npx). For development, you can start the server in HTTP mode (npm run dev) on http://localhost:3000/mcp or in stdio mode (npm run dev:stdio). Add the server to your MCP client configuration with the command mcp-api-tester or a path to the compiled stdio-server.js.
