## FAQ

### How much does it cost to generate a server?

A typical run costs roughly $0.05–$0.30 in API usage on the default model (Claude 3.5 Sonnet). Other commands like validate, inspect, list, doctor, and init are free.

### Can I try it without an Anthropic API key?

Yes, you can use the demo command which runs the pipeline against a built-in recording to produce a validated weather server without an API key.

### What is included in a generated server project?

It produces a complete project including tools, Pydantic input validation, error handling, a pytest suite, run configuration, and client setup documentation.
