## FAQ

### What does the context preflight tool do?

It counts GPT-family tokens, applies an optional model-aware budget, and redacts likely credentials to prepare repository text for an LLM.

### Is the context preflight service free?

The local MCP tool provides a free tier for inputs up to 12,000 characters, while larger inputs require the paid HTTP endpoint.

### Does the API send my text to a third party?

No, the API is designed so that processing is done locally and does not send submitted text to a third party.

### How much does a context preflight request cost?

The default price for the paid endpoint is $0.005 per request.
