How do I use tool calling with Cohere Command?

Short answer: You can chat with tools in Cohere by hand from its own interface, but it won’t repeat itself. On TinyCommand, add the Cohere Chat with Tools action to a workflow, map its 4 inputs from any upstream app, and it runs automatically every time the trigger fires. No code, and a free tier to start.

FAQ

Questions about Chat with Tools.

What does the Chat with Tools action do in Cohere?
Chats with Cohere Command models with tool/function calling enabled. Use to let the model fetch data, run actions, or build agents within Cohere's ecosystem.
What inputs does Chat with Tools require?
Required: User Message, Tools. Every input accepts a static value or a variable from any upstream node in your workflow.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Cohere returns an error?
The run history shows the failed step with its input and the error message Cohere returned, so you can fix the input and run the workflow again. Automatic retries are built into HTTP steps only, where you can also set your own retry count and delay.
Does Chat with Tools support batch operations?
Run Chat with Tools inside a loop to process each item in an array. TinyCommand does not throttle calls for you, so for large arrays add a Delay step if you need to stay within Cohere's rate limits.
