Implementation Reference
- src/index.ts:926-943 (handler)The handler function that executes the tool logic: destructures input parameters, builds query params, fetches data from Macrostrat columns API endpoint, and returns the JSON response as text content.
async (request) => { const { lat, lng, adjacents, responseType } = request; const params = new URLSearchParams({ lat: lat.toString(), lng: lng.toString(), adjacents: adjacents?.toString() ?? "false", response: responseType, }); const response = await fetch(`${getApiEndpoint("columns")}?${params}`); const data = await response.json(); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } - src/index.ts:916-925 (schema)The tool metadata including title, description, and inputSchema with Zod validators for the parameters.
