How to Set Up and Use Postman Tool Generator
The Postman Tool Generation MCP Server connects AI agents to the Postman API to automatically convert Postman collections and individual requests into type-safe, framework-specific code that AI agents can use as tools. Given a collection ID and request ID, it generates complete implementations — including type definitions, error handling, and documentation — targeting frameworks like OpenAI, Anthropic, LangChain, Mistral, Gemini, or AutoGen. Teams that already maintain Postman collections can rapidly turn their API documentation into callable AI agent tools without writing boilerplate code.
Prerequisites
- Node.js 18 or later and npm
- A Postman account with an API key from https://web.postman.co/settings/me/api-keys
- Access to Postman Public API Network collections (collection ID and request ID)
- An MCP-compatible client such as Claude Desktop, Cline, or Cursor
Clone and build the server
Clone the MCP server repository and build it with npm.
git clone https://github.com/giovannicocco/mcp-server-postman-tool-generation
cd mcp-server-postman-tool-generation
npm install
npm run buildObtain your Postman API key
Log into Postman and navigate to Settings > API Keys to generate a new API key. This key authenticates the server's requests to the Postman API.
Find your Postman collection and request IDs
Navigate to the Postman Public API Network and find the collection you want to generate tools from. Copy the collection ID and the specific request ID you want to convert.
Configure the MCP client
Add the server to your MCP client's settings file, providing the path to the built server and your Postman API key as an environment variable.

}
}
}
}Restart your MCP client
Restart Claude Desktop or your MCP client to load the new server configuration. The generate_ai_tool tool will now be available.
Generate your first AI tool
Ask your AI assistant to generate a tool from a Postman collection and request, specifying the language and target AI framework.

- "Create an OpenAI JavaScript function from collectionID: 12345-abcde requestID: 67890-fghij"
- "Convert this Postman request to a LangChain tool in TypeScript"
- "Generate an AutoGen Python tool for Postman collection 99999-zzzzz request 11111-aaaaa"Troubleshooting Postman Tool Generator
POSTMAN_API_KEY authentication error or 401 Unauthorized
Verify the API key is correct and has not expired in your Postman account settings at https://web.postman.co/settings/me/api-keys. Ensure the key is placed in the env block of the MCP config without extra spaces or quotes.
Collection or request ID not found
Collection and request IDs must be from the Postman Public API Network. Private workspace collections may not be accessible via the public API. Verify the IDs by navigating to the collection in Postman and checking the URL or collection info panel.
Build fails or node cannot find the index.js file
Ensure npm run build completed without errors before starting the server. The compiled output should be in the build/ directory. If the directory is missing, re-run npm install followed by npm run build and verify no TypeScript compilation errors.
