Overview

postman-mcp-server connects MCP-compatible AI agents and coding assistants to Postman through remote or local deployments. It offers Minimal, Code, Full, and Learn configurations for managing Postman resources, generating client code, accessing API context, or searching Postman Docs. Use the remote endpoint for OAuth-based access, or run the npm package locally when an agent needs to work with APIs on your workstation. The local server and EU endpoints use Postman API key authentication.

Use cases

  • Manage collections from an AI coding assistant
  • Synchronize API definitions with application code
  • Generate client code from API specifications
  • Create workspaces and update environment variables
  • Test APIs hosted on a local workstation

Key features

  • Postman workspace, collection, and environment operations
  • Minimal, Code, Full, and Learn tool configurations
  • Client-code generation from API definitions
  • Postman Docs search
  • Remote OAuth and local API-key authentication
  • EU region support

How Postman MCP Server works

What postman-mcp-server does

postman-mcp-server exposes Postman operations through the Model Context Protocol. Agents and coding assistants can work with Postman workspaces, collections, specifications, and environments without switching away from their host application.

The server supports four tool configurations. Minimal is the default and focuses on essential operations for individual Postman resources. Code adds client-code generation from public and internal API definitions. Full exposes more than 100 Postman API tools for broader collaboration and Enterprise workflows. Learn searches Postman Docs for guides, tutorials, reference material, and API concepts.

Typical uses include maintaining collections and environments, synchronizing API definitions with application code, creating specifications from code, generating collections from specifications, and producing client code for APIs.

How it works

You can connect to Postman’s remote MCP service over streamable HTTP or launch the package locally over STDIO. The remote service uses OAuth at https://mcp.postman.com; its path selects the tool configuration, with /minimal for the default set, /code for code generation, and /mcp for Full mode. Remote access is suitable when the agent only needs the hosted Postman connection.

Run the local package with npx @postman/postman-mcp-server. Add --code or --full to select those configurations. Local execution is the relevant option for testing APIs on a developer’s workstation because the remote server cannot reach that workstation’s network.

Setup and configuration

For a local installation, provide a Postman API key through POSTMAN_API_KEY. The EU region can be selected with --region eu, or configured through POSTMAN_API_BASE_URL. The EU remote endpoints are available at https://mcp.eu.postman.com/mcp for Full mode, /code, and /minimal.

OAuth is available on the primary remote service and does not require manually configuring an API key. The EU remote and local deployments use API key authentication instead. Postman publishes the server as the @postman/postman-mcp-server npm package and provides setup guidance for supported agents and IDEs.

Tools and capabilities

  • Manage Postman collections, including creating, updating, tagging, documenting, commenting, and handling multiple collections.
  • Create and manage workspaces and environments, including environment variables.
  • Generate client code from public or internal API definitions.
  • Create specifications from application code and generate collections from specifications.
  • Search Postman Docs for feature guidance, tutorials, reference content, and API concepts.
  • Access the broader Postman API tool set through Full mode, which contains more than 100 tools.

Limitations and notes

The remote service cannot access APIs running on the local workstation, so local execution is needed for those testing scenarios. OAuth is not supported by the EU remote server. Tool availability depends on the selected configuration: Minimal is intentionally narrower, while Code, Full, and Learn add different capabilities rather than exposing one identical tool set.

A Postman MCP Server collection can be used to browse available tools and test the remote or local connection. Docker setup is also available for the local deployment.

Frequently Asked Questions about Postman MCP Server

postman-mcp-server is an MCP server that connects AI agents and coding assistants to Postman workspaces, collections, specifications, and environments. Its main tools support Postman operations, client-code generation, broad Postman API access, and Postman Docs search through Minimal, Code, Full, and Learn configurations.

Install it locally by running `npx @postman/postman-mcp-server`. Set `POSTMAN_API_KEY` for authentication, and add `--code` or `--full` to select those tool configurations. You can also connect an MCP host to the remote `https://mcp.postman.com/minimal` endpoint.

Yes, postman-mcp-server supports Cursor in both remote and local configurations. Use the corresponding MCP setup for Cursor and choose the remote endpoint or the locally launched npm package.

Yes, run the local server to test APIs available on your workstation. The remote server cannot access the workstation’s network, so remote connections are not suitable for that use case.

Use the EU remote endpoints or start the STDIO package with `--region eu`. You can also set `POSTMAN_API_BASE_URL`; EU connections use Postman API key authentication rather than OAuth.
