What is GitNexus?
GitNexus is an open-source, MCP-native knowledge-graph engine that indexes any codebase into a graph of dependencies, call chains, clusters, and execution flows. It provides deterministic, compiler-grade static analysis to help AI agents understand entire systems rather than just files. It integrates with popular coding agents like Claude Code, Cursor, and Codex, and offers a browser-based web UI for exploration.
How to use GitNexus?
- To use GitNexus, you can start with the open-source version by running a single command to index your repository. It provides 7 MCP tools for querying, context, impact analysis, and more. You can integrate it with your preferred coding agent (e.g., Claude Code, Cursor) and use the browser web UI to explore the knowledge graph. For enterprise needs, you can contact the team for the Nexus Agent or Enterprise plans.
