Implementation Reference
- src/index.ts:1063-1078 (handler)The handler function for the 'timescale' tool. It accepts an 'age' input, constructs a query to the Macrostrat API /v2/defs/intervals endpoint using timescale_id=11, fetches the data, and returns it as formatted JSON text.
async (request) => { const { age } = request; const params = new URLSearchParams({ timescale_id: "11", age: age.toString(), }); const response = await fetch(`${getApiEndpoint("base")}/v2/defs/intervals?${params}`); const data = await response.json(); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } - src/index.ts:1056-1062 (schema)Input schema specification for the 'timescale' tool, including title, description, and required 'age' parameter (number).
{ title: "Timescale", description: "Get information about a time period", inputSchema: { age: z.number().describe("Age in millions of years before present"), } }, - src/index.ts:1054-1079 (registration)Registration of the 'timescale' MCP tool using server.registerTool, including the tool name, schema, and handler function.
server.registerTool( "timescale", { title: "Timescale", description: "Get information about a time period", inputSchema: { age: z.number().describe("Age in millions of years before present"), } }, async (request) => { const { age } = request; const params = new URLSearchParams({ timescale_id: "11", age: age.toString(), }); const response = await fetch(`${getApiEndpoint("base")}/v2/defs/intervals?${params}`); const data = await response.json(); return { content: [{ type: "text" as const, text: JSON.stringify(data, null, 2) }] }; } );
