First-party remote Model Context Protocol server that exposes Channel99 marketing intelligence - visits, pixel impressions, vendor and channel scores, audiences, account identity and pipeline influence - to an external LLM under read-only controls, including a guarded SQL-backed data interface. OAuth 2.1 with PKCE against a Stytch authorization server on a Channel99 subdomain, with RFC 9728 protected-resource and RFC 8414 authorization-server metadata both published. Channel99 ships connectors for OpenAI ChatGPT (GA) and Anthropic Claude (beta). Tool schemas require an authenticated tools/list.
