Postman MCP Server

The Postman MCP Server connects Postman to AI tools, giving AI agents and assistants the ability to access workspaces, manage collections and environments, evaluate APIs, and automate workflows through natural language interactions.

Postman supports the following tool configurations:

• Minimal — (Default) Only includes essential tools for basic Postman operations This offers faster performance and simplifies use for those who only need basic Postman operations. Ideal for users who want to modify a single Postman elements, such as collections, workspaces, or environments.
• Full — Includes all available Postman API tools (100+ tools). This configuration is ideal for users who engage in advanced collaboration and Postman's Enterprise features.
• Code — Includes tools to generate high-quality, well-organized client code from public and internal API definitions. This configuration is ideal for users who need to consume APIs or simply get context about APIs to their agents.

For a complete list of the Postman MCP Server's tools, see the Postman MCP Server collection. This collection offers both the remote full and minimal servers, and the local server.

Postman also offers servers as an npm package.

Authentication

For the best developer experience and fastest setup, use OAuth on the remote server (https://mcp.postman.com). OAuth is fully compliant with the MCP Authorization specification and requires no manual API key configuration. The EU remote server and the local server (this repo/npm package) support only Postman API key authentication.

Use Cases

• API Testing — Continuously test your API using your Postman collection. To be able to test local APIs, use the local server, as the remote server won't have network access to your workstation.
• Code synchronization — Effortlessly keep your code in sync with your Postman Collections and specs.
• Collection management — Create and tag collections, update collection and request documentation, add comments, or perform actions across multiple collections without leaving your editor.
• Workspace and environment management — Create workspaces and environments, plus manage your environment variables.
• Automatic spec creation — Create specs from your code and use them to generate collections.
• Client code generation — Generate production-ready client code that consumes APIs following best practices and project conventions. The code toolset produces code that precisely matches your API definitions, organizes it into an intuitive tree structure mirroring your Postman collections and requests, and leverages example responses to create accurate response types and error handling.

Designed for developers who want to integrate their AI tools with Postman's context and features. Supports quick natural language queries to advanced agent workflows.
