GitNexus (45k Github stars) is a Knowledge Graph Kernel that unifies every codebase in your org into one source of truth your coding agents can query. It resolves your code into a deterministic graph, so agents get exact callers, imports, and impact instead of embedding guesses, across every repo and SCM you run. On our public benchmark (https://www.akonlabs.com/benchmarks), coding agent runs 51% cheaper with GitNexus connected. It works with any agent over MCP.
