async ({ a, b }) => { const diff = a - b; return { content: [ { type: "text", text: `The difference of ${a} and ${b} is ${diff}` } ] }; } - src/index.ts:64-64 (schema)The input schema for the 'subtract' tool, defining 'a' and 'b' as numbers using Zod validation.
inputSchema: { a: z.number(), b: z.number() }, - src/index.ts:59-74 (registration)The registration of the 'subtract' tool on the MCP server, including name, metadata, schema, and handler function.
server.registerTool( "subtract", { title: "Subtraction tool", description: "Subtract b from a (a - b)", inputSchema: { a: z.number(), b: z.number() }, }, async ({ a, b }) => { const diff = a - b; return { content: [ { type: "text", text: `The difference of ${a} and ${b} is ${diff}` } ] }; } );
