l402-llm-mcp

Pay-per-query LLM access over Lightning (L402), exposed as an MCP server.

Website: pyfile-toolkit.github.io — overview, pricing and discovery across x402, Lightning (L402) and Nano.

What it is

A single Node.js server that serves two things:

  • MCP endpoint POST /mcp (streamable HTTP, tool: chat)
  • OpenAI-compatible POST /v1/chat/completions

Payment is enforced by the L402 protocol: every request returns a Lightning invoice (10 sats short, 50 sats long). Models are proxied to a free LLM backend (gemini-3.6-flash, gpt-oss-120b).
