A calculator tool lets an AI agent delegate arithmetic instead of asking the language model to calculate. It evaluates an expression deterministically and returns the numeric result. section 5.3
In Langflow, turning a calculator component into an agent-ready tool involves three stages:
- Enable Tool Mode so the component exposes a tool connection. section 5.3
- Review or edit the function definition, such as evaluate_expression(), which performs basic arithmetic. section 5.3
- Connect the calculator’s Toolset output to the agent, allowing the agent to call it when calculations are needed. section 5.3
Figure 5.7 Our Calculator component has become a calculator tool.
Shows the calculator component after Tool Mode transforms it into a tool. section 5.3
