Why Generic HighLevel MCP Servers Flood Claude's Context Window

Community Node.js MCP wrappers dump 150 to 253 raw OpenAPI tool schemas into Claude on every turn, consuming 35,000+ context tokens before you type a single word and lacking any dry-run safety checks.

Native OAuth 2.1 Streamable HTTP + Progressive Discovery for Claude

1-Click Hosted OAuth 2.1 (`https://ghlagencymcp.com/mcp`) with S256 PKCE works in Claude Desktop, Claude Web, and Claude iOS/Android.
Local zero-knowledge `stdio` setup via `ghl-agency init-config --client claude` for Claude Code and power builders.
Progressive Discovery Mode (`--progressive`) starts with 6 bootstrap tools (`ghl_agency_connection_health`, `ghl_agency_tools_search`, `ghl_agency_tools_enable`, `ghl_agency_contexts`, `ghl_agency_doctor`, `ghl_agency_run`) and dynamically enables domain packs (`core`, `onboarding`, `saas`, `ai`, `telephony`, `commerce`, `governance`) with `notifications/tools/list_changed`.
Server-enforced Safe-Writes policies (`--policy read-only|no-sending|no-deletes|full-access`).

Frequently Asked Questions

Does Progressive Discovery work automatically in Claude?

Yes. When Claude calls `ghl_agency_tools_enable` for a domain pack (such as `onboarding` or `telephony`), the server emits `notifications/tools/list_changed` so Claude immediately sees the newly enabled tools.

Is Claude Code supported?

Yes, both via remote Streamable HTTP (`https://ghlagencymcp.com/mcp`) and local native `stdio` (`ghl-agency mcp --progressive --policy no-deletes`).
