Personalbrain MCP

The first city on the Lightning Turnpike. An MCP server that gives AI agents read-write access to a personal knowledge graph - and pays for itself with Bitcoin Lightning micropayments. It is available as a remote MCP endpoint.

Teams that work with bitcoin, btcpayserver and fastmcp and want a hosted endpoint instead of running a local process. The project is written in Python.
