### Answer --- Yes, custom tools work inside Components. [(1) ]() The documentation explicitly states: > "Components can include function nodes and use your configured tools. Tools behave the same as in the main flow." There is one important note: tools need to be defined within the component itself and will not be visible outside at the agent level. You can also see in the API responses for Components that they include a

tools

array where custom tools can be defined: [(2) ]() , [(3) ]()

json
"tools": [
  {
    "type": "custom",
    "name": "get_customer_info",
    "description": "Get customer information from database",
    "tool_id": "tool_001",
    "url": "<https://api.example.com/customer%22,>
    "method": "GET"
  }
]

[(2) ]()
