Agent X402 Paywall Mcp

Implements Coinbase's HTTP 402 Payment Required protocol to let AI agents pay for each API call they make, with settlement happening on-chain. Exposes tools to list supported blockchain networks, build 402 payment challenges, and verify payments before granting access to paywalled resources. Reach for this when you're building agent-to-agent or agent-to-service interactions where you want micropayments per request instead of API keys or subscriptions. The stdio transport integrates with Claude Desktop via uvx, while the streamable-http endpoint at api.meok.ai handles remote calls. Useful if you're experimenting with economic protocols for autonomous agents or want to monetize your own MCP servers on a per-call basis.
