Nano Pay MCP Server

Self-custodied Nano (XNO) wallet + x402 payment client and merchant server, built for AI agents. Client spends; nano-pay serve earns - paid endpoints, on-ledger verification/settlement (no facilitator), a starter faucet, and the railHint x402 extension that teaches visiting agents how to onboard (see SPEC-railhint.md). Site: site/index.html + site/llms.txt.

People who work with http 402, micropayments and nanocurrency and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.
