Implementation Reference
- src/tools/calculatorTool.ts:16-48 (handler)The handler function that executes the 'calculate' tool logic, performing basic arithmetic operations (add, subtract, multiply, divide) on two numbers and returning the result or error for division by zero.async ({ operation, a, b }) => { let result: number | undefined; switch (operation) { case 'add': result = a + b; break; case 'subtract': result = a - b; break; case 'multiply': result = a * b; break; case 'divide': if (b === 0) { return { content: [{ type: 'text', text: 'Error: Division by zero is not allowed.' }], isError: true, }; } result = a / b; break; } return { content: [ { type: 'text', text: `Result of ${operation}(${a}, ${b}) = ${result}`, }, ], }; }
- src/tools/calculatorTool.ts:11-15 (schema)Input schema for the 'calculate' tool, defining the operation type and two numeric operands using Zod.{ operation: z.enum(['add', 'subtract', 'multiply', 'divide']), a: z.number(), b: z.number(), },
- src/tools/calculatorTool.ts:9-49 (registration)Registration of the 'calculate' tool on the MCP server instance, including schema and handler.server.tool( 'calculate', { operation: z.enum(['add', 'subtract', 'multiply', 'divide']), a: z.number(), b: z.number(), }, async ({ operation, a, b }) => { let result: number | undefined; switch (operation) { case 'add': result = a + b; break; case 'subtract': result = a - b; break; case 'multiply': result = a * b; break; case 'divide': if (b === 0) { return { content: [{ type: 'text', text: 'Error: Division by zero is not allowed.' }], isError: true, }; } result = a / b; break; } return { content: [ { type: 'text', text: `Result of ${operation}(${a}, ${b}) = ${result}`, }, ], }; } );
