Building nervous system for agent context.

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

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

TL;DR: The Web UI is a quick way to chat with any repo. The CLI + MCP is how you make your AI agent actually reliable — it gives Cursor, Claude Code, 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, making it compete with goliath models.

Star History

Two Ways to Use GitNexus

	CLI + MCP	Web UI
What	Index repos locally, connect AI agents via MCP	Visual graph explorer + AI chat in browser
For	Daily development with Cursor, Claude Code, Codex, Windsurf, OpenCode	Quick exploration, demos, one-off analysis
Scale	Full repos, any size	Limited by browser memory (~5k files), or unlimited via backend mode
Install	npm install -g gitnexus	No install — gitnexus.vercel.app
Storage	LadybugDB native (fast, persistent)	LadybugDB WASM (in-memory, per session)
Parsing	Tree-sitter native bindings	Tree-sitter WASM
Privacy	Everything local, no network	Everything in-browser, no server

Bridge mode: gitnexus serve connects the two — the web UI auto-detects the local server and can browse all your CLI-indexed repos without re-uploading or re-indexing.

Development

• ARCHITECTURE.md — packages, index → graph → MCP flow, where to change code
• RUNBOOK.md — analyze, embeddings, stale index, MCP recovery, CI snippets
• GUARDRAILS.md — safety rules and operational “Signs” for contributors and agents
• CONTRIBUTING.md — license, setup, commits, and pull requests
• TESTING.md — test commands for gitnexus and gitnexus-web

CLI + MCP (recommended)

The CLI indexes your repository and runs an MCP server that gives AI agents deep codebase awareness.

Quick Start

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

That's it. This indexes the codebase, installs agent skills, registers Claude Code hooks, and creates AGENTS.md / CLAUDE.md context files — all in one command.

To configure MCP for your editor, run npx gitnexus setup once — or set it up manually below.

MCP Setup

gitnexus setup auto-detects your editors and writes the correct global MCP config. You only need to run it once.

Editor Support

Editor	MCP	Skills	Hooks (auto-augment)	Support
Claude Code	Yes	Yes	Yes (PreToolUse + PostToolUse)	Full
Cursor	Yes	Yes	—	MCP + Skills
Codex	Yes	Yes	—	MCP + Skills
Windsurf	Yes	—	—	MCP
OpenCode	Yes	Yes	—	MCP + Skills

Claude Code gets the deepest integration: MCP tools + agent skills + PreToolUse hooks that enrich searches with graph context + PostToolUse hooks that auto-reindex after commits.

Community Integrations

What Your AI Agent Gets

16 tools exposed via MCP (11 per-repo + 5 group):

Tool	What It Does	repo Param
list_repos	Discover all indexed repositories	—
query	Process-grouped hybrid search (BM25 + semantic + RRF)	Optional
context	360-degree symbol view — categorized refs, process participation	Optional
impact	Blast radius analysis with depth grouping and confidence	Optional
detect_changes	Git-diff impact — maps changed lines to affected processes	Optional
rename	Multi-file coordinated rename with graph + text search	Optional
cypher	Raw Cypher graph queries	Optional
group_list	List configured repository groups	—
group_sync	Extract contracts and match across repos/services	—
group_contracts	Inspect extracted contracts and cross-links	—
group_query	Search execution flows across all repos in a group	—
group_status	Check staleness of repos in a group	—

When only one repo is indexed, the repo parameter is optional. With multiple repos, specify which one: query({query: "auth", repo: "my-app"}).

Resources for instant context:

Resource	Purpose
gitnexus://repos	List all indexed repositories (read this first)
gitnexus://repo/{name}/context	Codebase stats, staleness check, and available tools
gitnexus://repo/{name}/clusters	All functional clusters with cohesion scores
gitnexus://repo/{name}/cluster/{name}	Cluster members and details
gitnexus://repo/{name}/processes	All execution flows
gitnexus://repo/{name}/process/{name}	Full process trace with steps
gitnexus://repo/{name}/schema	Graph schema for Cypher queries

2 MCP prompts for guided workflows:

Prompt	What It Does
detect_impact	Pre-commit change analysis — scope, affected processes, risk level
generate_map	Architecture documentation from the knowledge graph with mermaid diagrams

4 agent skills installed to .claude/skills/ automatically:

• Exploring — Navigate unfamiliar code using the knowledge graph
• Debugging — Trace bugs through call chains
• Impact Analysis — Analyze blast radius before changes
• Refactoring — Plan safe refactors using dependency mapping

Repo-specific skills generated with --skills:

When you run gitnexus analyze --skills, GitNexus detects the functional areas of your codebase (via Leiden community detection) and generates a SKILL.md file for each one under .claude/skills/generated/. Each skill describes a module's key files, entry points, execution flows, and cross-area connections — so your AI agent gets targeted context for the exact area of code you're working in. Skills are regenerated on each --skills run to stay current with the codebase.

Multi-Repo MCP Architecture

GitNexus uses a global registry so one MCP server can serve multiple indexed repos. No per-project MCP config needed — set it up once and it works everywhere.

    ConnB -->|"queries"| RepoB

How it works: Each gitnexus analyze stores the index in .gitnexus/ inside the repo (portable, gitignored) and registers a pointer in ~/.gitnexus/registry.json. When an AI agent starts, the MCP server reads the registry and can serve any indexed repo. LadybugDB connections are opened lazily on first query and evicted after 5 minutes of inactivity (max 5 concurrent). If only one repo is indexed, the repo parameter is optional on all tools — agents don't need to change anything.

Web UI (browser-based)

A fully client-side graph explorer and AI chat. No server, no install — your code never leaves the browser.

Try it now: gitnexus.vercel.app — drag & drop a ZIP and start exploring.

Or run locally:

git clone https://github.com/abhigyanpatwari/gitnexus.git
cd gitnexus/gitnexus-shared && npm install && npm run build
cd ../gitnexus-web && npm install
npm run dev

Docker

The official Docker setup ships two signed images orchestrated by docker-compose.yaml:

Image	Purpose
ghcr.io/abhigyanpatwari/gitnexus:latest	CLI / gitnexus serve backend (HTTP API on port 4747, MCP, indexer)
ghcr.io/abhigyanpatwari/gitnexus-web:latest	Static web UI (port 4173)

Heads-up — image rename. Earlier releases published the web UI under
ghcr.io/abhigyanpatwari/gitnexus. Starting with the introduction of the
bundled backend, that slug now hosts the CLI/server image and the UI moved
to ghcr.io/abhigyanpatwari/gitnexus-web. The previous tags remain
available for pulling, but new versions are only published under the new
slugs. Update your docker run / compose files accordingly (or just adopt
the bundled compose).

One-command setup

docker compose up -d

This starts the server on http://localhost:4747 and the web UI on
http://localhost:4173. The UI auto-detects the server because the browser
runs on the host and reaches the container via the mapped port.

A named volume (gitnexus-data) persists the global registry, indexes, and
cloned repos at /data/gitnexus inside the server container. To make repos on
your host machine indexable, set WORKSPACE_DIR before bringing the stack up:

WORKSPACE_DIR=$HOME/code docker compose up -d
# Inside the server container the directory is mounted read-only at /workspace.
docker compose exec gitnexus-server gitnexus index /workspace/my-repo

Direct docker run

# Server
docker run --rm -d \
  --name gitnexus-server \
  -p 4747:4747 \
  -v gitnexus-data:/data/gitnexus \
  ghcr.io/abhigyanpatwari/gitnexus:latest

# Web UI
docker run --rm -d \
  --name gitnexus-web \
  -p 4173:4173 \
  ghcr.io/abhigyanpatwari/gitnexus-web:latest

Optional env file (override image tags, container names, ports, workspace dir):

cp .env.example .env
docker compose --env-file .env up -d

Versioning & supply-chain protection

The Docker images are version-locked to the npm package:

• Stable images are only published from vX.Y.Z git tags (via docker.yml
  triggered directly by the tag push), and the workflow refuses to build unless
  the tag exactly matches gitnexus/package.json's version. So
  ghcr.io/abhigyanpatwari/gitnexus:1.6.2 is byte-for-byte the same release
  as npm install [email protected] — no drift, no floating builds from main.
• Release-candidate images (e.g. :1.7.0-rc.1) are published alongside each
  RC npm release. They are built by release-candidate.yml calling docker.yml
  as a reusable workflow after the RC tag is created and pushed.
• :latest is auto-promoted only from non-prerelease tags by the Docker
  metadata action, so it always points at a real, npm-published version.

Both images are signed with Cosign keyless signing using the
workflow's GitHub OIDC identity, and shipped with build provenance and SBOM
attestations. This is your protection against supply-chain attacks: even if
an attacker republishes a same-named image elsewhere (or somehow pushes to a
typo-squatted registry), they cannot forge a Cosign signature tied to
abhigyanpatwari/GitNexus's docker.yml. Always verify before pulling into
sensitive environments:

Stable releases — signed from the v* tag ref:

cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
  --certificate-identity-regexp '^https://github\.com/abhigyanpatwari/GitNexus/\.github/workflows/docker\.yml@refs/tags/v[0-9]+\.[0-9]+\.[0-9]+(-[a-zA-Z0-9.]+)?$' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

The regex pins the certificate identity to this repo's docker.yml workflow
run from a v* tag — rejecting unsigned images, images signed by other
workflows, and images signed from unprotected refs.

Release candidates — signed from refs/heads/main (the caller's ref when
release-candidate.yml invokes docker.yml as a reusable workflow):

cosign verify ghcr.io/abhigyanpatwari/gitnexus:1.7.0-rc.1 \
  --certificate-identity 'https://github.com/abhigyanpatwari/GitNexus/.github/workflows/docker.yml@refs/heads/main' \
  --certificate-oidc-issuer https://token.actions.githubusercontent.com

You can also inspect the build provenance and SBOM:

cosign download attestation ghcr.io/abhigyanpatwari/gitnexus:1.6.2 \
  --predicate-type https://slsa.dev/provenance/v1

Kubernetes: enforce signatures at admission

For Kubernetes deployments, ship the bundled
ClusterImagePolicy so the
Sigstore policy-controller rejects any GitNexus pod whose
image is not signed by this repo's docker.yml running from a vX.Y.Z tag —
the same identity the cosign verify snippet above pins.

# 1. Install the controller (one-time, cluster-wide)
helm repo add sigstore https://sigstore.github.io/helm-charts && helm repo update
helm install policy-controller -n cosign-system --create-namespace \
  sigstore/policy-controller

# 2. Opt your namespace in
kubectl label namespace <your-ns> policy.sigstore.dev/include=true

# 3. Apply the policy
kubectl apply -f deploy/kubernetes/cluster-image-policy.yaml

After this, attempting to deploy an unsigned image — or one signed by anything
other than abhigyanpatwari/GitNexus's docker.yml at a v* tag — fails the
admission webhook before a pod is ever created. This turns the verifiable
signature into an enforced policy, which is the supply-chain control most
clusters actually need.

Files

• Dockerfile.web — builds gitnexus-shared and gitnexus-web, then serves the production frontend.
• Dockerfile.cli — builds the CLI/server (with its native deps) and runs gitnexus serve --host 0.0.0.0.
• docker-compose.yaml — starts both signed images side by side.
• .env.example — overrides for image names, container names, ports, and the workspace mount.

The web UI uses the same indexing pipeline as the CLI but runs entirely in WebAssembly (Tree-sitter WASM, LadybugDB WASM, in-browser embeddings). It's great for quick exploration but limited by browser memory for larger repos.

Local Backend Mode: Run gitnexus serve and open the web UI locally — it auto-detects the server and shows all your indexed repos, with full AI chat support. No need to re-upload or re-index. The agent's tools (Cypher queries, search, code navigation) route through the backend HTTP API automatically.

The Problem GitNexus Solves

Tools like Cursor, Claude Code, Codex, Cline, Roo Code, and Windsurf are powerful — but they don't truly know your codebase structure.

What happens:

1. AI edits UserService.validate()
2. Doesn't know 47 functions depend on its return type
3. Breaking changes ship

Traditional Graph RAG vs GitNexus

Traditional approaches give the LLM raw graph edges and hope it explores enough. GitNexus precomputes structure at index time — clustering, tracing, scoring — so tools return complete context in one call:

flowchart TB
    subgraph Traditional["Traditional Graph RAG"]
        direction TB
        U1["User: What depends on UserService?"]
        U1 --> LLM1["LLM receives raw graph"]
        LLM1 --> Q1["Query 1: Find callers"]
        Q1 --> Q2["Query 2: What files?"]
        Q2 --> Q3["Query 3: Filter tests?"]
        Q3 --> Q4["Query 4: High-risk?"]
        Q4 --> OUT1["Answer after 4+ queries"]
    end

    subgraph GN["GitNexus Smart Tools"]
        direction TB
        U2["User: What depends on UserService?"]
        U2 --> TOOL["impact UserService upstream"]
        TOOL --> PRECOMP["Pre-structured response:
        8 callers, 3 clusters, all 90%+ confidence"]
        PRECOMP --> OUT2["Complete answer, 1 query"]
    end

Core innovation: Precomputed Relational Intelligence

• Reliability — LLM can't miss context, it's already in the tool response
• Token efficiency — No 10-query chains to understand one function
• Model democratization — Smaller LLMs work because tools do the heavy lifting

---

How It Works

GitNexus builds a complete knowledge graph of your codebase through a multi-phase indexing pipeline:

1. Structure — Walks the file tree and maps folder/file relationships
2. Parsing — Extracts functions, classes, methods, and interfaces using Tree-sitter ASTs
3. Resolution — Resolves imports, function calls, heritage, constructor inference, and self/this receiver types across files with language-aware logic
4. Clustering — Groups related symbols into functional communities
5. Processes — Traces execution flows from entry points through call chains
6. Search — Builds hybrid search indexes for fast retrieval

Wiki Generation

Generate LLM-powered documentation from your knowledge graph:

# Requires an LLM API key (OPENAI_API_KEY, etc.)
gitnexus wiki

# Use a custom model or provider
gitnexus wiki --model gpt-4o
gitnexus wiki --base-url https://api.anthropic.com/v1

# Force full regeneration
gitnexus wiki --force

The wiki generator reads the indexed graph structure, groups files into modules via LLM, generates per-module documentation pages, and creates an overview page — all with cross-references to the knowledge graph.
