Implementation Reference
- src/tools/example.ts:35-53 (handler)Handler implementation for 'example-tool' that extracts input, validates with Zod, processes via helper function, and returns the tool result.
'example-tool': async (request) => { try { const { input } = request.params.arguments as { input: string } const inputSchema = z.object({ input: z.string().min(1, 'Input must not be empty') }) inputSchema.parse({ input }) const result = await handleExampleProcess(input) return { toolResult: { content: [{ type: 'text', text: result }], }, } } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error) throw new Error(`Failed to process input: ${errorMessage}`) } } - src/tools/example.ts:8-22 (schema)Tool schema definition for 'example-tool' including name, description, and input schema.
const EXAMPLE_TOOL: Tool = { name: 'example-tool', description: 'An example tool that processes input data', inputSchema: { type: 'object', properties: { input: { type: 'string', description: 'Input string to process', minLength: 1 } }, required: ['input'] } } - src/index.ts:21-22 (registration)Combines example tools and handlers into global collections used by the MCP server for tool listing and execution.
const ALL_TOOLS = [...EXAMPLE_TOOLS] const ALL_HANDLERS = { ...EXAMPLE_HANDLERS } - src/index.ts:31-34 (registration)Registers the request handler for listing available tools, which includes 'example-tool' via ALL_TOOLS.
server.setRequestHandler(ListToolsRequestSchema, async () => { log('Received list tools request') return { tools: ALL_TOOLS } }) - src/tools/example.ts:28-31 (helper)Helper function called by the tool handler to process the input string.
async function handleExampleProcess(input: string): Promise<string> { log('Processing input:', input) return `Processed: ${input}` }
