Tools
GEOMETRY exposes curated tools over MCP. Same engine on Path B HTTP later.
Coming next (beta roadmap): name cards, birthday engine, team compatibility.
All string fields in tool JSON are lowercase except glyph fields. No nulls — sentinels like
none, 0, [].
Full payload / raw JSON: same thing — the complete object the tool returns. There is no full_payload flag; each tool’s only levers are its date inputs. Builders integrating MCP/HTTP get the whole payload on the wire every time. Chat UIs may summarize what the agent already received — if you want it pasted verbatim, ask the agent to show the raw tool result (that instruction is to the model, not to GEOMETRY).
