Input Schema
TableJSON Schema
| Name | Required | Description | Default |

| responseType | No | The length of response long or short. Long provides lots of good details | long |
Implementation Reference
- src/index.ts:957-973 (handler)The handler function for the 'find-units' tool. It takes lat, lng, and optional responseType ('long' or 'short'), queries the Macrostrat units API, and returns the JSON data as text content.
async (request) => { const { lat, lng, responseType } = request; const params = new URLSearchParams({ lat: lat.toString(), lng: lng.toString(), response: responseType, }); const response = await fetch(`${getApiEndpoint("units")}?${params}`); const data = await response.json(); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } - src/index.ts:948-956 (schema)The tool schema defining title, description, and inputSchema using Zod for validation of lat, lng (required numbers), and responseType (enum with default).
{ title: "Find Units", description: "Find geological rock units, formations, bedrock geology, and mineral information for any location worldwide. Use for geology questions, rock types, age dating, lithology, and geological analysis.", inputSchema: { lat: z.number().describe("A valid latitude in decimal degrees"), lng: z.number().describe("A valid longitude in decimal degrees"), responseType: z.enum(["long", "short"]).default("long").describe("The length of response long or short. Long provides lots of good details"), } }, - src/index.ts:946-974 (registration)The server.registerTool call that registers the 'find-units' tool with its schema and inline handler function.
