This plugin connects coding agents such as Claude Code, Cursor, and Codex to Postman, letting the agent handle API design, mocking, testing, documentation, monitoring, and Flow deployment directly from the command line. It stores collections, environments, and other API resources as individual files on disk so changes produce small, reviewable Git diffs. It also exposes a Context Graph that combines data from Postman workspaces, GitHub, and New Relic so the agent can trace dependencies and likely impact before editing code. A companion feature builds local mocks from OpenAPI specs or collections that can later be pushed to a hosted URL. Several CLI commands send usage analytics by default, and some minimal command-run signals cannot be turned off outside the EU region according to the README's telemetry section.
About the service
Postman is a platform for designing, testing, mocking, monitoring, and documenting APIs, with workspaces that store specifications, collections, environments, and monitors; this plugin lets an agent read and manipulate those same resources through a local file structure and CLI commands, and it can also pull in GitHub repository data and New Relic telemetry to build its cross-system Context Graph.
What you can do with postman
- Set up a repository's Postman file structure (collections, environments, specs) for agent-driven editing
- Query the Context Graph with a natural-language question to see what a proposed API change might affect
- Generate and run a local mock API from an OpenAPI spec or collection before the real service exists
- Run collection and governance checks suitable for CI pipelines
- Monitor a deployed API endpoint
- Deploy and troubleshoot Postman Flows
- Publish generated API documentation
- Control or limit telemetry reporting for individual CLI commands, with some exceptions noted in the README
