Kit API v4

In your Kit account, open the Developer settings, click Add a new key, give it an internal name, and copy the generated key. Kit only shows the key once; if you lose it, reset it from the same page.

Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
