Straight answers about the live MCP server.
Everything here describes the production /mcp surface inside the HumanDesign.ai API.
What is Human Design MCP?
It is the remote MCP surface of the HumanDesign.ai API. Compatible AI clients can discover and call six structured Human Design tools through one hosted Streamable HTTP endpoint.
Is this a separate Human Design calculation engine?
No. MCP, Agent HTTP, and REST are integration surfaces of the same HumanDesign.ai engine and share one API key, entitlement system, and monthly quota.
How many live MCP tools are there?
Six: resolve_timezone, generate_chart, generate_composite_chart, get_reference_item, get_transits, and search_celebrities. Tool visibility depends on your plan.
Which clients can connect?
Any compatible Streamable HTTP MCP client can connect. The documentation includes guides for Claude, Codex, Cursor, and VS Code.
What consumes API quota?
A successful tools/call consumes one shared API unit. initialize, ping, and tools/list do not consume quota.
Can Free API members use MCP?
Yes. Free includes 100 calls each month and the four core MCP tools: timezone resolution, core bodygraph generation, composite generation, and reference lookup.
