Implementation Reference

• lib/fixed-mcp-tool.js:389-402 (handler)

  The handler implementation for the 'timeout-test' tool. It destructures the duration argument, logs the call, and returns a Promise that resolves after the specified duration using setTimeout, simulating a timeout test.

  case "timeout-test":
      const { duration } = args;
      console.error('[GMCPT] timeout-test tool called with duration: ' + duration + 'ms');
      
      return new Promise((resolve) => {
          setTimeout(() => {
              resolve({
                  content: [{
                      type: "text",
                      text: `Timeout test completed after ${duration}ms`
                  }]
              });
          }, Math.max(10, duration));
      });

• lib/fixed-mcp-tool.js:199-213 (schema)

  The schema definition for the 'timeout-test' tool, specifying the name, description, and input schema requiring a 'duration' number parameter (minimum 10ms). This schema is returned by the ListTools endpoint.

  {
      name: "timeout-test",
      description: "Test timeout prevention by running for a specified duration",
      inputSchema: {
          type: "object",
          properties: {
              duration: {
                  type: "number",
                  minimum: 10,
                  description: "Duration in milliseconds (minimum 10ms)"
              }
          },
          required: ["duration"]
      }
  }

• lib/fixed-mcp-tool.js:217-219 (registration)

  Registration of the ListTools request handler, which exposes the 'timeout-test' tool schema (included in the 'tools' array) to MCP clients.

  server.setRequestHandler(ListToolsRequestSchema, async () => {
      return { tools };
  });
