Navi X402 MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 26 installs a week from npm. Last commit 11 Jun 2026.
Paid agent tools, zero API keys: crypto, weather, translation, web intel, x402 discovery (USDC/Base)
Today is the operative word: we check Navi X402 MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
