@xenarch/agent-mcpMCP Server42/100 via “non-custodial usdc micropayment settlement on base l2”
x402 MCP server for AI agent payments. Lets Claude, Cursor, LangChain and CrewAI pay for HTTP 402–gated APIs with USDC micropayments on Base L2. Non-custodial, 0% fee. Unlike Cloudflare Pay-Per-Crawl, works on any host and settles directly on-chain.
Unique: Implements non-custodial payment settlement where the MCP server never holds or controls agent funds — only constructs and signs transactions using agent-provided key material. Uses Base L2 instead of mainnet Ethereum to achieve sub-cent transaction costs (~$0.001 per transfer) while maintaining full on-chain settlement and auditability.
vs others: Eliminates counterparty risk vs custodial payment processors (Stripe, PayPal) by settling directly on-chain; cheaper than mainnet Ethereum by 100-1000x due to Base L2 rollup architecture; more transparent than traditional APIs with hidden fees.
