x402node/x402-mcp

Overview

An MCP server that exposes 100+ paid APIs to AI agents using x402 protocol stablecoin micropayments. It auto-syncs API listings from CDP Bazaar and supports multi-chain payments across Base, Solana, Polygon, BNB, and EVM. Designed for agentic commerce, it integrates with MCP-aware clients like Claude and Cursor.

Use cases

• Enable AI agents to call paid APIs on demand with instant micropayments
• Automate machine-to-machine payments for autonomous workflows
• Access developer utilities, validators, and encoders through a standardized interface

Pros

• Broad multi-chain payment support reduces platform lock-in
• Auto-syncing from CDP Bazaar keeps API list current without manual updates
• Works with any MCP-aware client, not tied to a single vendor

Cons

• Zero GitHub stars suggests very early or unpopular project
• Dependence on x402 protocol and stablecoin rails may limit adoption in non-crypto setups
• Limited to APIs listed on CDP Bazaar; no custom endpoint configuration documented
