MCP server verification and compatibility preflight before deployment, with testing, evaluation, x402 payment, and PASS/FAIL evidence.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.
Attributed to the source that supplied each field. Treated as claims, not facts.
ProofRail performs MCP server verification before deployment, upgrade, or trust. It tests and evaluates protocol negotiation, tools/list, schemas, transport, and authentication classification, then returns PASS, FAIL, or PARTIAL with deterministic evidence. Certification is paid through x402; Gate 1 currently uses Base Sepolia test-USDC.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
