Overview

ProofRail 0.4.0 provides free MCP discovery and compatibility preflight. Paid contract checks accept required_tools and baseline_schema_hashes, detect removed tools and schema changes, and return detailed evidence, a reusable contract baseline and payment-linked public receipt verification. Schema drift requires review; it does not prove incompatibility. HTTP x402 and MCP interfaces. Base mainnet USDC, $0.10 per paid check.
