Instructions

Implementation Reference

• src/mcp_server_undetected_chromedriver/server.py:293-297 (handler)

  The handler function for the 'browser_close' tool. It calls reset_browser_state() to quit the webdriver and returns a success response.

  @mcp.tool()
  async def browser_close():
      """Close the browser and release all resources"""
      await reset_browser_state()
      return await create_success_response("Browser closed successfully")

• src/mcp_server_undetected_chromedriver/server.py:27-30 (helper)

  Helper function that quits the global webdriver instance and sets it to None.

  async def reset_browser_state():
      if Global.webdriver:
          Global.webdriver.quit()
          Global.webdriver = None

• src/mcp_server_undetected_chromedriver/server.py:41-47 (helper)

  Helper function to create a successful CallToolResult response.

  async def create_success_response(message: str | list[str]) -> types.CallToolResult:
      if isinstance(message, str):
          message = [message]
      return types.CallToolResult(
          content=[TextContent(type="text", text=msg) for msg in message],
          isError=False,
      )

• src/mcp_server_undetected_chromedriver/server.py:293-297 (registration)

  The @mcp.tool() decorator registers the browser_close function as an MCP tool.

  @mcp.tool()
  async def browser_close():
      """Close the browser and release all resources"""
      await reset_browser_state()
      return await create_success_response("Browser closed successfully")
