Try Postman with your agent

Connect Postman, then paste this into Claude, ChatGPT or Cursor. For ideas from other apps, see the use cases.

Using Corsair, show me what you can do in Postman on my account, then run one read-only example and show me the result.

Postman tools and triggers

Tools are what your agent can do in Postman through Corsair's MCP server. Triggers are the Postman events a routine can start from.

Connect Postman to Claude, ChatGPT or Cursor

  1. 1

    Connect Postman in Corsair

    Add your Postman API key once in Corsair. Corsair stores the credential encrypted and makes the Postman API calls for your agent, so it never goes into a prompt or a config file. Connect Postman

    If your link lets the agent add apps, you can skip this: it gives you a sign-in link the first time it needs Postman. On a ChatGPT personal plan, connect Postman here first.

  2. 2

    Add Corsair's MCP server to your agent

    Every client uses the same address:

    https://mcp.corsair.dev/mcp
    Open Customize → Connectors → Add custom connector, paste the address, then select Connect.

    Codex, Gemini CLI, VS Code, Zed and other clients with OAuth sign-in work the same way. Clients without it, such as GitHub Copilot's coding agent, use a link's own address and an API key. Setup for every client

  3. 3

    Sign in and choose what needs your approval

    Your client opens Corsair to sign in. Pick a link: the apps your agent can use and a mode that decides what it may do without asking. In the default Cautious mode, Postman's read and write operations run right away and its 16 destructive operations wait for your approval. Strict mode asks before every write and refuses destructive operations, and Read mode allows reads only.

FAQ

Install corsair and @corsair-dev/postman, add the Postman plugin, and connect with an API key. Then call methods like corsair.postman.api.accessKeys.list() from your app. Corsair syncs data per tenant.

Yes. Postman requires an API key from your Postman account or developer dashboard. Create credentials with access that matches what you automate, then paste them into Corsair or connect through managed auth in Hub.

Yes. One Corsair client can hit Postman, GitHub, Notion, Stripe, and the rest. Trigger Postman from a webhook, push updates to Slack, or chain actions across plugins. Same tenant context across integrations, plain TypeScript.

Teams use Corsair for api platform for managing collections, workspaces, environments, mock servers, monitors, specs, apis, comments, and webhooks. Common builds include sync jobs, admin tooling, and agents that call Postman APIs from your backend. Local DB entities let you query synced Postman records without hitting the API on every read.

The SDK is open source. Self-host and you pay Corsair nothing for the integration layer. Hub bills for hosted auth and execution, not per Postman API call. Hub has a generous free tier. For hobby projects you can probably run the whole thing on free. Paid plans start to matter with more tenants or heavier traffic.

We maintain @corsair-dev/postman in the open repo. When Postman ships API changes, upgrade the package. Your call sites stay typed. You should not need to rewrite the integration layer each time.

No. Corsair does not read your Postman data or hold individual access credentials. Credentials stay in your database. API calls run on your instance. We do not store Postman data on your behalf.

Yes. Add https://mcp.corsair.dev/mcp as a custom connector or MCP server in Claude, ChatGPT, Cursor, VS Code, Claude Code, Codex or any client that supports remote MCP servers with OAuth sign-in, then sign in to Corsair. On ChatGPT personal plans, custom servers currently get read tools only.

Yes. Put Postman on a link in Strict mode and every write waits for your approval, while destructive actions are refused. The default Cautious mode asks only before the 16 destructive Postman operations. You can change a link's mode at hub.corsair.dev/me.
