Preflight

What is Preflight?

Preflight provides independent reliability ratings for every API and MCP server, acting as a “TrustPilot for APIs” built for AI agents. It uses synthetic probes and crowdsourced agent telemetry rather than vendor self-reporting.

How to use Preflight?

Install with pip install preflight-mcp. Optionally set the PREFLIGHT_API_KEY environment variable (free key at beamt.io/preflight) to unlock sub-scores and higher rate limits. Use the three tools—check_reliability, compare_services, and report_outcome—to look up ratings, compare services, or leave reviews.
