HighLevel REST API

In HighLevel, open the target agency or sub-account, go to Settings → Private Integrations, click Create New Integration, choose the required scopes, create it, and copy the token. The auth guide is Private Integrations, and the MCP setup article shows the same path under sub-account settings in How to Setup and Use the HighLevel MCP Server.

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.
