Nuthatch MCP

Nuthatch is a self-hosted, AI-native blockchain indexer that turns an EVM contract's history into a local SQL database. It includes a built-in MCP server providing tools for schema discovery, SQL execution, entity lookup, and balance queries, allowing agents to interact with indexed on-chain data locally without third-party services.
