A0nexus Bitcoin MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 88 installs a week from npm. Last commit 13 Jul 2026.
Crypto (BTC/ETH) + ERCOT electricity data & forecasts as MCP tools. Pay-per-call via x402.
Today is the operative word: we check A0nexus Bitcoin MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

This one needs environment variables set before it will start:
BTCI_API_URL (Base URL of the a0nexus API.), BTCI_MCP_PAYMENT (Set to 'real' to enable the paid tools (otherwise only the free tools work).), BTCI_MCP_PRIVATE_KEY (Base wallet private key used to pay for paid tools when BTCI_MCP_PAYMENT=real.).
The author declared them in the registry entry; get the values from the project itself.
