Manage your Postman workspaces in Claude Desktop

Stop hunting for links in the browser. Use `list_workspaces` and `get_workspace_details` to see your team's API setup without leaving your chat window. It’s about seeing the structure of your project immediately. You get the full picture of your API hierarchy right where you're already writing specs.

Debug API environments with Claude Desktop

Run `list_environments` to see exactly which variable sets are active for your current task. You can then pull specific data with `get_environment_details` to verify your configuration. This keeps your context grounded in reality. No more guessing if you’re hitting dev or production endpoints.

Check your API mocks via Claude Desktop

Use `list_mocks` to verify that your simulated endpoints are live before you start coding against them. You can also monitor your health checks using `list_monitors`. It saves you from writing code against stale mocks. You get the status of your API simulation instantly, letting you pivot if something is down.
