npx normieclaw-mcpYour agent doesn't need to be deployed on NormieClaw. Any agent anywhere can use BrainFuel as a failover — just swap your base URL and add two headers. Your primary provider works first, BrainFuel catches it when it goes down. One change, automatic failover.

BrainFuel is the cheapest way to keep agents thinking. USDC in, intelligence out.
