Full read-write Claude connector for Postman
Let Claude create requests and run collections in Postman
Stop clicking through the Postman app to build and test your APIs. Claude creates and edits requests where your collections already live, updates environments, and runs collections on demand, with you approving anything that changes a shared workspace or hits a live endpoint.
Postman is the API development platform where teams design, test, document, and monitor their APIs. People want Claude to do more than describe a collection: to create and update requests, run them, and manage environments and mock servers directly.
What is a Postman MCP server?
A Postman MCP server is a small hosted service that exposes Postman's data and actions to Claude over the Model Context Protocol, so Claude can issues, code, and incidents inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.
What can Postman's current connector do today?
Today, Postman's connection to Claude tends to be read-leaning where one exists at all: Claude can reference collections, requests, and docs, but creating requests, editing environments, running collections, and managing workspaces are limited or unavailable. A custom Postman connector adds those write actions through the Postman API with scoped, human-in-the-loop controls.
What does full read-write Postman access unlock?
Full read-write Postman access lets Claude create and edit requests inside a collection, update environment variables, run a collection or folder, build mock servers, and organize workspaces. The API design and test setup that used to mean clicking through the app happen where your collections already live, with you approving anything that changes shared state.
- Create a new request in a collection with headers, body, and auth
- Update environment variables across a workspace
- Run a collection or folder and report the test results
- Add or edit tests and pre-request scripts on a request
- Create a mock server from an existing collection
- Organize requests into folders and rename collections
Can Claude create and edit requests in Postman?
Yes. Claude can create a new request in a collection with headers, body, and auth, then edit its tests and pre-request scripts. A full read-write connector exposes these write tools through the Postman API, so building requests happens in your collection instead of by hand in the app.
Can Claude run a collection and report the test results in Postman?
Claude can run a collection or folder and report back the test results. Because a run hits live endpoints, it is a gated action: Claude prepares the run and proceeds only after you approve it, so nothing fires against a real API by surprise.
Can Claude manage environments and mock servers in Postman?
Claude can update environment variables across a workspace and create a mock server from an existing collection. Edits to shared environments and workspaces are gated write actions that wait for your confirmation, and the connector never gets more access than your own Postman account already has.
How a Postman connector works
We build a small MCP server that authenticates to Postman with a scoped API key, never more access than your own account already has. Read tools (list collections, read requests) and write tools (create request, update environment) are separated, and a run action executes a collection via Newman or the Postman CLI, or triggers a Postman Monitor, rather than a Postman API write. Actions that change shared workspaces or run requests against live endpoints are gated behind your confirmation. If your Postman instance sits behind an allowlist, we can restrict the server to approved IPs.
