}Auth is OAuth 2.1 against Clay with Dynamic Client Registration (DCR) and PKCE. Cursor registers itself and prompts for Clay sign-in when the plugin connects — there is no API key or client ID to configure.
You need a Clay account with access to a workspace.
Your Clay workspace admin may need to allow MCP client connections under Clay workspace Settings → MCP. If sign-in succeeds but tools fail, check with your admin.
