Implementation Reference
- server.js:1658-1682 (registration)Tool registration for 'increase_camera_fov' - defines the tool's metadata (title, description), input schema (optional amount parameter), and the complete handler function that executes when the tool is called. The handler routes a command to the current browser session with type 'increaseCameraFOV' and returns a success message.
mcpServer.registerTool( 'increase_camera_fov', { title: 'Increase Camera Field of View', description: 'Increase the camera field of view (wider angle, see more of the scene)', inputSchema: { amount: z.number().positive().optional().describe('Optional amount to increase (defaults to configured FOV speed)') } }, async ({ amount }) => { routeToCurrentSession({ type: 'increaseCameraFOV', amount: amount }); return { content: [ { type: 'text', text: amount ? `Camera FOV increased by ${amount}` : 'Camera FOV increased (wider angle)' } ] }; } ); - server.js:1658-1682 (handler)The actual handler function for 'increase_camera_fov' (lines 1667-1682) that executes when the tool is invoked. It accepts an optional 'amount' parameter, routes the command to the current session via routeToCurrentSession(), and returns a formatted response indicating the FOV was increased.

It retrieves the current session ID from AsyncLocalStorage context and forwards the command.
