Needs a Postman account. The US remote server signs in with OAuth; the EU server and the local npx server need a Postman API key. The endpoint picks a tool set: /minimal (default), /code, /mcp (full, 100+ tools), /learn or /context-graph. Postman's docs say coding agents working in a repo should prefer the Postman CLI and its agent skills. Remote servers collect anonymous telemetry.
