The outcome
- Client engagements that previously needed bespoke Make.com flows now resolve through agentic conversation.
- Every category the official MCP missed — blogs, social media, granular opportunity updates, custom fields — became accessible.
- It sets up a moat: any agency relying on the official MCP is structurally limited in what it can offer.
The challenge
The official GoHighLevel MCP server exposes 36 tools — enough for trivial automations, but not for real agentic work across the platform's 19 functional categories. Every Stories and Systems engagement that wanted AI-driven CRM work ran into the same ceiling.
How we did it
- Reverse-mapped the entire GoHighLevel API surface into a modular MCP architecture organized by category: contacts, opportunities, calendars, conversations, blogs, social posting, payments, locations, and more.
- Built 461-plus tools, each with strict input validation, opinionated defaults, and AI-readable descriptions tuned for high triggering accuracy.
- Category modules load selectively so the token budget stays controlled.
- Productized to deploy per client with their own credentials, isolated from other tenants.
The official MCP felt like being handed a screwdriver to disassemble an engine. So we built the rest of the toolbox.
