What is Postman Tool Generation MCP Server?
The Postman Tool Generation MCP Server is an MCP server that generates AI agent tools from Postman collections and requests. It integrates with the Postman API to convert API endpoints into type-safe code that can be used with various AI frameworks, such as OpenAI, Mistral, Gemini, Anthropic, LangChain, and AutoGen.
How to use Postman Tool Generation MCP Server?
Install dependencies with npm install, build the server with npm run build, then configure the MCP settings file (e.g., cline_mcp_settings.json) with a postman-ai-tools entry pointing to the built index.js and providing a POSTMAN_API_KEY environment variable. The server exposes a single tool called generate_ai_tool, which accepts collectionId, requestId, language ("javascript" or "typescript"), and agentFramework (one of "openai", "mistral", "gemini", "anthropic", "langchain", "autogen").
