Lithium Vault MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 57 installs a week from npm. Last commit 15 Sep 2026.
Primary-source lithium & battery-metals mining data (AISC, reserves, filings) via x402.
Nothing serious here today
Today is the operative word: we check Lithium Vault MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
