## FAQ

### Does the MCP server send my secrets to a remote service?

The optimize_prompt_payload tool sends request bodies to the TokenZero service, so you should avoid including secrets in those bodies.

### Can I use this in my CI/CD pipeline?

Yes, you can use a GitHub Action to check pull requests for cost changes.

### Are the audit numbers exact?

The numbers provided are estimates based on list prices; actual verified savings are provided by the gateway's signed ledger.
