Nano Pay is a Model Context Protocol (MCP) server: Pay for x402-priced APIs with feeless, sub-second Nano (XNO) micropayments from a local wallet. In practice that means any MCP-compatible AI assistant can call Nano Pay's tools directly — the model decides when to use them in a conversation or agent run.
It runs locally: the Python package feeless402 (via uvx) speaks MCP over stdio on your machine. No credentials are required — it works out of the box. The current release is v0.2.4, published under the MIT license, with source at Feeless402/feeless402 on GitHub.
Nano Pay is listed under Finance on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
