LeanKG vs vurb.ts

LeanKG: LeanKG is a local-first knowledge graph that provides accurate codebase context to AI coding tools. It indexes code, builds dependency graphs, and exposes an MCP server for direct querying. No cloud services or external databases are required.; vurb.ts: Vurb.ts is a TypeScript framework for building production-grade MCP servers using the MVA (Model-View-Agent) pattern. It provides structured perception, data security, and anti-hallucination mechanisms. Developers can quickly scaffold servers with file-based routing, Presenters, and built-in features like PII redaction and FSM state gates.
