Calculator

Use the built-in Calculator tool in LibreChat agents

Calculator is a built-in agent tool for arithmetic and symbolic calculations. It does not require an API key or environment variable.

Setup

In LibreChat, select Agents, create or edit an agent, open the agent's Tools list, select Calculator, and save the agent.

Ask the agent to calculate something that benefits from a tool call:

Calculate 12345 * 6789 and show the result.

If Calculator is not visible in the Agent Builder, check whether your librechat.yaml uses includedTools or filteredTools.
