Fair-price verification and leaderboard management for x402/MPP micropayment protocol.

What is the io.github.Antmanbuilds/ari-mcp-py MCP server?

The ARI MCP server is a Python-based Model Context Protocol server that provides fair-price checks, leaderboards, and Ed25519 receipt verification for the x402/MPP (Micropayment Protocol) ecosystem. It enables verification of pricing fairness and management of payment-related leaderboards through cryptographic receipt validation.

ARI integrates micropayment protocol functionality into MCP-compatible AI agents. It allows you to verify fair pricing, manage leaderboards, and validate cryptographic receipts using Ed25519 signatures—useful for applications built on the x402/MPP payment standard.
