Tool Calling Agent
The Tool Calling Agent empowers AI flows to automatically select and use configured tools to solve user queries, making workflows more powerful and adaptive.
Component description
How the Tool Calling Agent component works
The Tool Calling Agent is a specialized component designed for AI workflows that require an agent to intelligently interact with a set of external tools in response to a user’s prompt. This component can orchestrate tool usage, manage chat history for context, and utilize language models to generate effective follow-up questions and actions.
What Does This Component Do?
The Tool Calling Agent acts as an intermediary that receives user input (typically a message), processes it using a language model, and determines which tools (from a provided list) to call in order to fulfill the request. It is capable of multi-step reasoning and can iterate over tool calls up to a specified maximum number of iterations. This approach is especially useful for complex AI tasks that require external data fetching, calculations, or integrations with APIs.
Inputs
The component accepts the following inputs:
| Name | Type | Required | Description |
|---|---|---|---|
| Inputs | Message | Yes | The main user input or message to be processed by the agent. |
| Tools | List of Tool | Yes | A list of tools the agent can use to answer the user’s query. |
| LLM | BaseChatModel | No | The language model used to generate responses and follow-up questions. |
| Chat History | InMemoryChatMessageHistory | No | Maintains the conversation context for more coherent and relevant agent responses. |
| Max Iterations | int | No | Sets the maximum number of reasoning steps the agent can take (default: 20). |
| System Message | str | No | An optional system prompt to guide the agent’s behavior or set context for the conversation. |
Outputs
- Message: The primary output is a Message object that contains the agent’s response after processing the input and (if needed) utilizing one or more tools.
Key Features & Usefulness
- Multi-tool Orchestration: Enables the agent to choose and invoke multiple tools as needed to resolve complex queries.
- Contextual Awareness: By leveraging chat history, the agent can generate more accurate and context-aware follow-up questions and actions.
- Iterative Reasoning: The agent can perform multiple reasoning steps (up to the defined max iterations), making it capable of handling tasks that require several interactions.
- Customizable Guidance: The optional system message allows you to influence the agent’s behavior, tone, or objectives, making it adaptable to different tasks or applications.
- Flexible Integration: Can be used in a variety of workflows that require dynamic decision-making, tool calling, or contextual conversation management.
Example Use Cases
- Automated Customer Support: The agent can call knowledge base search tools, ticket creation APIs, or other utilities in response to user questions.
- Data Retrieval and Processing: The agent could fetch data from various sources (APIs, databases) and process it before responding.
- Conversational AI Applications: Enables multi-turn dialog where the agent maintains context and interacts with external services to complete tasks.
