## FAQ

### Does FSB require an API key to work with MCP clients?

No, when using an MCP client like Claude Desktop or Cursor, your client's model handles the reasoning and no FSB API key is needed.

### How does FSB differ from vision-based browser agents?

Unlike agents that rely on screenshots, FSB uses the page structure (DOM, selectors, ARIA, and forms) directly, which results in lower latency and lower token costs.

### Can FSB upload local files during automation?

Yes, it includes a supervised upload_file tool that allows uploading real local files to file inputs with sensitive-path safeguards.

### What AI models can I use with the FSB extension?

The extension supports xAI, Gemini, OpenAI, Anthropic, OpenRouter, LM Studio, and custom OpenAI-compatible endpoints.
