The Celina stack
One shared tool catalog on Celo mainnet — celina-sdk defines reads, wallet flows, and LLM tools; celina-mcp and the hosted endpoint register them for agents; browser apps filter the same definitions with surface: "browser".
Architecture
Everything flows from the SDK tool catalog. Hosts filter by surface (mcp vs browser) and wire signing their own way.
