Implementation Reference

• src/mcp_server_undetected_chromedriver/server.py:199-219 (handler)

  The handler function for the 'browser_fill' tool. It validates inputs, ensures the browser is ready, finds the element by CSS selector, fills it with the provided value using send_keys, and returns a success response.

  @mcp.tool()
  async def browser_fill(
          selector: str,
          value: str,
  ):
      """fill out an input field
  
      Args:
          selector: CSS selector for input field - required
          value: The value to fill - required
      """
      assert selector, "Selector is required"
      assert value, "Value is required"
  
      async def fill_handler(driver: uc.Chrome):
          driver.find_element(By.CSS_SELECTOR, selector).send_keys(value)
          return await create_success_response(f"Filled {selector} with: {value}")
  
      return await tool.safe_execute(
          ToolContext(webdriver=await ensure_browser()), fill_handler
      )
