Create and use AI tools in Postman

Postman supports AI-driven development with AI requests in collections and AI Request blocks in Postman Flows. You can use AI requests and AI Request blocks to explore model behavior and add AI-assisted logic to flows.

With the Postman AI Tool Builder, you can also generate MCP servers that expose AI tools from public APIs in the Postman API Network. Each MCP server exposes API requests as tools that language models and other MCP-compatible clients can call. You can customize the server code, run it locally, and iterate on tool behavior from within your Postman workflow.

Create AI requests and add them to your collections

You can create AI requests to interact with AI models. You can then prompt the model, review the response details, and manage your conversations with them. In addition, you can edit your AI request settings to change how you interact with the model.

Create AI Request blocks and add them to your flows

With the Postman AI Tool Builder and Postman Flows, you can use a visual, low-code editor to build API-first AI agents on an infinite, drag-and-drop canvas.

To learn more, see Add your AI request blocks to your flows.

Create MCP requests and add them to your collections

You can use Postman as your Model Context Protocol (MCP) client and send requests to MCP servers. You can use these MCP requests to help you build and test your MCP server, or evaluate one from the community.

Create MCP servers

With the Postman AI Tool Builder, you can create MCP servers and AI tools from public APIs on the Postman API Network. Your MCP servers can expose AI tools and data so MCP clients can interact with them.
