Implementation Reference
- src/tools/handlers.ts:79-95 (handler)The main handler function for the 'open_app' tool. It extracts the package_name from args, runs 'adb shell monkey -p {package_name} 1' to launch the app, sleeps for 5 seconds, and returns a text confirmation.
open_app: async (args: any) => { const { package_name } = args as { package_name: string; }; await executeCommand(`adb shell monkey -p ${package_name} 1`); await sleep(5000); return { content: [ { type: 'text', text: `App opened: ${package_name}`, }, ], }; }, - src/tools/definitions.ts:30-43 (schema)The schema definition for the 'open_app' tool, specifying the input schema that requires a 'package_name' string.
{ name: 'open_app', description: 'Open an app using its package name and activity', inputSchema: { type: 'object', properties: { package_name: { type: 'string', description: 'Full package name of the app (e.g., com.example.app)', }, }, required: ['package_name'], }, }, - src/index.ts:26-30 (registration)Registration of tool list handler, which returns all tool definitions including 'open_app' schema.
server.setRequestHandler(ListToolsRequestSchema, async () => { return { tools: toolDefinitions, }; }); - src/index.ts:32-46 (registration)Registration of tool call handler, which dispatches to the specific tool handler like 'open_app' based on name.
server.setRequestHandler(CallToolRequestSchema, async (request) => { const { name, arguments: args } = request.params; try { const handler = toolHandlers[name as keyof typeof toolHandlers]; if (!handler) { throw new McpError(ErrorCode.MethodNotFound, `Unknown tool: ${name}`); } return await handler(args); } catch (error) { const errorMessage = error instanceof Error ? error.message : String(error); throw new McpError(ErrorCode.InternalError, `Tool execution failed: ${errorMessage}`); } });
