Is the Postman skill free?

Yes. The skill itself is free from SterlingChin/postman-claude-skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Postman SkillProof Score?

7.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 4/5.

How do I install Postman?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Postman with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 7.6/10
Tested: Jul 25, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Jul 30, 2026 · aca4cd9

⚠ This skill is no longer available upstream. Our re-check on Aug 10, 2026 couldn't find it any more (repo unreachable/deleted). The test below is what we measured on Jul 25, 2026 and we're leaving it up as a record — but there is nothing left to install, so we've removed the command.

validate_setup.py runs cleanly and reports missing-key diagnostics; a dummy key hits a real 401 from api.getpostman.com, so every core action is gated behind a Postman account key I could not supply. Real output vs a no-skill baseline is therefore unmeasured, and the SKILL.md leans on heavy v1.1 marketing, so it stays at setup rather than pass.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

Installs cleanly 5/5
Triggers reliably 5/5

Docs & honesty 4/5

What Postman does

Drives the Postman API through bundled Python scripts to discover collections and workspaces, create and validate API specs, run Newman tests, manage environments with auto-secret detection, and analyze monitors. Triggers when you mention Postman, collections, API specs, or API testing. Requires a Postman API key in .env.

How to install Postman

Nothing to install: the source repository no longer has this skill. If the author brings it back, our daily re-check will pick it up and the command will reappear here.

Commands — how to trigger Postman

/postman Manage the Postman API lifecycle: collections, specs, tests, monitors, mocks

It also activates on plain-language prompts like these:

List my Postman collections and run the Newman tests
Generate a Postman collection from this OpenAPI spec
Set up environments and check for exposed secrets in Postman
