Postman

ConnectionMCP

Give API context to your coding agents with Postman.

Install

Connections live under agent/connections/. Auth is brokered by Vercel Connect, so install the framework and the Connect SDK:

Quick start

Create agent/connections/postman.ts. The connection name is derived from the filename:

// agent/connections/postman.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";
export default defineMcpClientConnection({  url: "https://mcp.postman.com/minimal",  description: "Postman: APIs, collections, and workspaces.",  auth: connect("postman"),});

// agent/connections/postman.tsimport { connect } from "@vercel/connect/eve";import { defineMcpClientConnection } from "eve/connections";
export default defineMcpClientConnection({  url: "https://mcp.postman.com/minimal",  description: "Postman: APIs, collections, and workspaces.",  auth: connect("postman"),});

Connect owns the OAuth flow, and each end-user authorizes in their own browser before their first tool call.

Configure

Link your project, create the connector, and pull OIDC locally:

See the Connections docs for principal types, headers, approval, and protocol-specific filters.
