GitNexus

The context engine for Enterprise Codebases

Indexes any codebase into a knowledge graph — every dependency, call chain, cluster, and execution flow — then exposes it through smart MCP tools so AI agents never miss code.

Gitnexus_CLI.1.mp4

Like DeepWiki, but deeper. DeepWiki helps you understand code. GitNexus lets you analyze it — a knowledge graph tracks every relationship, not just descriptions.

TL;DR: The CLI + MCP makes your AI agent reliable — it gives Cursor, Claude Code, Antigravity, Codex, and friends a deep architectural view of your codebase so they stop missing dependencies, breaking call chains, and shipping blind edits. Even smaller models get full architectural clarity. The Web UI is a quick way to chat with any repo in the browser.

Quick Start

# 1. Index your repo (run from repo root)
npx gitnexus analyze

# 2. Connect your editors (one-time, auto-detects Claude Code, Cursor, Codex, …)
npx gitnexus setup

That's it. analyze indexes the codebase, installs agent skills, registers Claude Code hooks, and creates AGENTS.md / CLAUDE.md context files — all in one command. setup writes the MCP config so your AI agent can use the graph.

Install problems? npm 11 crash · slow cold install · no C++ toolchain

On npm 11.x? npx can crash during install with Cannot destructure property 'package' of 'node.target' (an npm/arborist bug, before GitNexus runs). Use pnpm instead — it builds the native deps explicitly:
pnpm --allow-build=@ladybugdb/core --allow-build=gitnexus --allow-build=tree-sitter dlx gitnexus@latest analyze
Or install globally (npm install -g gitnexus@latest) and run gitnexus analyze. See #1939.

Fastest MCP startup: install globally (npm i -g gitnexus) before running gitnexus setup — this writes an absolute-path MCP config that bypasses npx entirely. On a cold cache, an
