Postman Plugin

Powering API engineering for agents

The Postman plugin brings filesystem-first API development and organization-wide API context to coding agents. It enables agents to design, mock, test, document, monitor, and ship APIs directly from Claude Code, Cursor, and Codex. Every operation produces inspectable files or CLI commands that fit naturally into Git and CI, while the Postman Context Graph helps agents understand dependencies, ownership, runtime behavior, and the likely impact of a change.

Install · Highlights

Install

Install Postman in every compatible coding agent detected on your machine:

bash
npx @postman/postman-plugin

One command configures Antigravity, Claude Code, Codex, GitHub Copilot CLI, Cursor, Factory Droid, Kimi Code, OpenCode and Pi. Run it again to update, status to see what's installed, and remove to uninstall; --agent <id> limits any of them to one agent.

For Codex, installation also approves Postman's session-start hook, which adds instructions for using Postman's API skills. There is no separate hook prompt or dump of its instructions. Already trusted hooks are left alone. If Codex's hook API is unavailable, installation continues with a note to approve the hook inside Codex. Run the installer and Codex with the same HOME and CODEX_HOME; hook approval applies to that profile. If Codex later refreshes the plugin from main and its contents change, run the installer again to approve the update.

You can also use the following commands to install individually:

Antigravity

bash
agy plugin install https://github.com/postmanlabs/postman-plugin

Run the same command again to update; agy plugin uninstall postman removes it. In the Antigravity app, Customizations → Plugins → + Install from URL takes the same URL.
