A GRAPH HAS NO CENTRE
Summary from the TLDR Data newsletter
Graph tools for MCP should return focused, bounded views instead of dumping broad subgraphs and hoping prompts impose structure later. The key design move is to make scope explicit in the server through named views, validation rules, and controlled navigation points. For changing entities like avatars, modeling location over time preserves auditability and keeps behavior consistent across clients.
