Implementation Reference
- src/tools/browserDisconnect.ts:6-26 (handler)The browserDisconnectHandler function that executes the browser_disconnect tool logic. It checks if a browser connection exists, disconnects via browserManager.disconnect(), and returns a success message or appropriate response if already disconnected.
export async function browserDisconnectHandler( _args: Record<string, never> ): Promise<ReturnType<typeof toolSuccess | typeof toolError>> { try { if (!browserManager.isConnected()) { return toolSuccess({ disconnected: true, message: 'Already disconnected (no active connection).', }); } await browserManager.disconnect(); return toolSuccess({ disconnected: true, message: 'Disconnected from Chrome (browser process is still running).', }); } catch (error) { return toolError(error); } } - src/tools/browserDisconnect.ts:4-4 (schema)The browserDisconnectSchema definition - an empty object indicating the tool requires no input parameters.
export const browserDisconnectSchema = {}; - src/index.ts:48-58 (registration)Registration of the browser_disconnect tool with the MCP server, including title, description, input schema reference, and handler function reference.
server.registerTool( 'browser_disconnect', { title: 'Disconnect from Chrome', description: 'Close the CDP connection to Chrome. Does NOT kill the Chrome process. ' + 'Call this when you are done to release the connection.', inputSchema: browserDisconnectSchema, }, browserDisconnectHandler );
