Nodeflare MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 87 installs a week from npm. Last commit 1 Aug 2026.
Blockchain JSON-RPC on 23 EVM chains for AI agents - free tier, API key, or x402 pay-per-call.
Today is the operative word: we check Nodeflare MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
