## FAQ

### How do I add SnapSurf to my MCP client?

You can add it as a stdio server using npx with the package @zumer/snapsurf@latest and the command snapsurf-mcp.

### Can SnapSurf use my existing browser sessions?

No, the daemon operates with its own cookies and storage, meaning it cannot access your personal signed-in sessions.

### What happens if an assertion fails?

Failed assertions will return a pass status of false and an MCP error status of true.

### Does SnapSurf support visual verification?

While it provides semantic reports, it has blind spots for canvas content and iframes; in those cases, you should inspect a scoped screenshot.
