assay-oracle-mcp

An MCP server that acts as a quality oracle for the x402 agent economy, allowing AI assistants to check a service's paid-probe quality tier and score before paying it. It provides composite scores, tier verdicts, and leaderboard data via HTTP endpoints that settle micropayments in USDC.
