ProofRail MCP
MCP server verification, testing, evaluation, and compatibility preflight before deployment.
Use ProofRail before deploying, upgrading, or trusting an MCP server. It checks protocol negotiation, tools/list, tool schemas, Streamable HTTP transport, authentication classification, and optional server-configured safe fixtures. It returns PASS, FAIL, or PARTIAL with deterministic evidence.

Current validation stage
Gate 1 runs on Base Sepolia at $0.001 test-USDC. Testnet payments are validation, not revenue. Base mainnet remains disabled.
The production ProofRail service code is not published in this repository. This repository contains only public discovery metadata, the static discovery landing page, and the automated MCP Registry publication workflow.
