Implementation Reference
- mcp-server/src/server.ts:484-493 (handler)The 'hello' tool handler - executed when the tool is called. Returns a greeting message using the provided 'name' argument, defaulting to 'world'.
case "hello": { return { content: [ { type: "text", text: `Hello, ${args?.name || "world"}!`, }, ], }; } - mcp-server/src/server.ts:107-120 (schema)Schema definition for the 'hello' tool, including its name, description, and input schema requiring a 'name' string property.
{ name: "hello", description: "A simple hello world tool", inputSchema: { type: "object", properties: { name: { type: "string", description: "The name to say hello to", }, }, required: ["name"], }, }, - mcp-server/src/server.ts:104-464 (registration)The 'setupToolHandlers' method registers both ListToolsRequestSchema and CallToolRequestSchema handlers, registering the 'hello' tool among other tools.
