</div>

## Get Started

**No Node.js required** — one command grabs the right build for your OS:

```bash
# macOS / Linux
curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh

# Windows (PowerShell)
irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex
```

Already have Node? Use npm instead (works on any version):

```bash
npx @colbymchenry/codegraph # zero-install, or:
npm i -g @colbymchenry/codegraph
```

<sub>CodeGraph bundles its own runtime — nothing to compile, no native build, works the same everywhere. The interactive installer auto-configures your agent(s) — Claude Code, Cursor, Codex CLI, opencode, Hermes Agent.</sub>

### Initialize Projects

```bash
cd your-project
codegraph init -i
```

![1_C_VYnhpys0UHrOuOgpgoyw](https://github.com/user-attachments/assets/f168182f-4d9a-44e0-94d7-08d018cc8a3a)

</div>

### Uninstall

Changed your mind? One command removes CodeGraph from every agent it configured:

```bash
codegraph uninstall
```

<sub>Reverses the installer — strips CodeGraph's MCP server config, instructions, and permissions from each configured agent. Your project indexes (`.codegraph/`) are left untouched; remove those per-project with `codegraph uninit`. Use `--target` to remove from specific agents, or `--yes` to run non-interactively.</sub>

---

## Why CodeGraph?

When Claude Code explores a codebase, it spawns **Explore agents** that scan files with grep, glob, and Read — consuming tokens on every tool call.

**CodeGraph gives those agents a pre-indexed knowledge graph** — symbol relationships, call graphs, and code structure. Agents query the graph instantly instead of scanning files.

### Benchmark Results

Tested across **7 real-world open-source codebases** spanning 7 languages, comparing an agent (Claude Code, headless) answering one architecture question **with** and **without** CodeGraph. Each cell is the savings at the **median of 4 runs per arm**. _Re-validated on **v0.9.4** (2026年05月24日)._

> **Average: 35% cheaper · 57% fewer tokens · 46% faster · 71% fewer tool calls**

| Codebase | Language | Cost | Tokens | Time | Tool calls |
|----------|----------|------|--------|------|------------|
| **VS Code** | TypeScript · ~10k files | 26% cheaper | 78% fewer | 52% faster | 85% fewer |
| **Excalidraw** | TypeScript · ~640 | 52% cheaper | 90% fewer | 73% faster | 96% fewer |
| **Django** | Python · ~3k | 12% cheaper | 36% fewer | 19% faster | 53% fewer |
| **Tokio** | Rust · ~790 | 82% cheaper | 86% fewer | 71% faster | 92% fewer |
| **OkHttp** | Java · ~645 | 2% cheaper | 13% fewer | 31% faster | 45% fewer |
| **Gin** | Go · ~110 | 21% cheaper | 34% fewer | 27% faster | 40% fewer |
| **Alamofire** | Swift · ~110 | 47% cheaper | 64% fewer | 48% faster | 83% fewer |

The gains scale with codebase size: on large repos the agent answers from the index in a handful of calls with **zero file reads**, while the no-CodeGraph agent fans out across grep/find/Read (and the sub-agents it spawns). On a small repo like Gin (~150 files) native search is already cheap, so the margin narrows.

<details>
<summary><strong>Full benchmark details</strong></summary>

**Methodology.** Each arm is `claude -p` (Claude Opus 4.7) run headlessly against the repo with `--strict-mcp-config`: **WITH** = CodeGraph's MCP server enabled, **WITHOUT** = an empty MCP config. Built-in Read/Grep/Bash stay available to both. Same question per repo, **4 runs per arm, median reported**. Cost = the run's `total_cost_usd`; Tokens = total tokens processed (input incl. cached + output); Time = wall-clock; Tool calls = every tool invocation, including those inside any sub-agents the model spawns. Repos cloned at `--depth 1` and indexed by the same CodeGraph build that served them. Re-validated on codegraph **v0.9.4** (2026年05月24日); per-repo numbers move run-to-run with how hard the without-arm thrashes (the median-of-4 smooths it, but tails remain — e.g. Tokio's without-arm hit 2ドル.41/3m one batch).

**Queries:**
| Codebase | Query |
|----------|-------|
| VS Code | "How does the extension host communicate with the main process?" |
| Excalidraw | "How does Excalidraw render and update canvas elements?" |
| Django | "How does Django's ORM build and execute a query from a QuerySet?" |
| Tokio | "How does tokio schedule and run async tasks on its runtime?" |
| OkHttp | "How does OkHttp process a request through its interceptor chain?" |
| Gin | "How does gin route requests through its middleware chain?" |
| Alamofire | "How does Alamofire build, send, and validate a request?" |

**Raw medians — WITH → WITHOUT:**
| Codebase | Cost | Tokens | Time | Tool calls |
|----------|------|--------|------|------------|
| VS Code | 0ドル.60 → 0ドル.80 | 601k → 2.8M | 1m 10s → 2m 26s | 8 → 55 |
| Excalidraw | 0ドル.43 → 0ドル.90 | 344k → 3.5M | 48s → 2m 58s | 3 → 79 |
| Django | 0ドル.59 → 0ドル.67 | 739k → 1.2M | 1m 19s → 1m 38s | 9 → 19 |
| Tokio | 0ドル.42 → 2ドル.41 | 379k → 2.6M | 53s → 3m 2s | 4 → 53 |
| OkHttp | 0ドル.47 → 0ドル.47 | 636k → 730k | 42s → 1m 1s | 6 → 11 |
| Gin | 0ドル.37 → 0ドル.47 | 444k → 675k | 44s → 1m 0s | 6 → 10 |
| Alamofire | 0ドル.61 → 1ドル.14 | 1.0M → 2.8M | 1m 17s → 2m 27s | 12 → 69 |

**Why CodeGraph wins:** with the index available, the agent answers directly — `codegraph_context` to map the area, then one `codegraph_explore` for the relevant source — and stops, usually with zero file reads. Without it, the agent (and the Explore sub-agents it spawns) spends most of its budget on discovery (find/ls/grep) before reading the right code. CodeGraph only helps when queried *directly*, so its instructions steer agents to answer directly rather than delegate exploration to file-reading sub-agents — otherwise a sub-agent reads files regardless and CodeGraph becomes overhead.

## Key Features

| | |
|---|---|
| **Smart Context Building** | One tool call returns entry points, related symbols, and code snippets — no expensive exploration agents |
| **Full-Text Search** | Find code by name instantly across your entire codebase, powered by FTS5 |
| **Impact Analysis** | Trace callers, callees, and the full impact radius of any symbol before making changes |
| **Always Fresh** | File watcher uses native OS events (FSEvents/inotify/ReadDirectoryChangesW) with debounced auto-sync — the graph stays current as you code, zero config |
| **19+ Languages** | TypeScript, JavaScript, Python, Go, Rust, Java, C#, PHP, Ruby, C, C++, Swift, Kotlin, Dart, Lua, Luau, Svelte, Liquid, Pascal/Delphi |
| **Framework-aware Routes** | Recognizes web-framework routing files and links URL patterns to their handlers across 14 frameworks |
| **100% Local** | No data leaves your machine. No API keys. No external services. SQLite database only |

---

## Framework-aware Routes

CodeGraph detects web-framework routing files and emits `route` nodes linked by `references` edges to their handler classes or functions. Querying callers of a view/controller now surfaces the URL pattern that binds it.

| Framework | Shapes recognized |
|---|---|
| **Django** | `path()`, `re_path()`, `url()`, `include()` in `urls.py` (CBV `.as_view()`, dotted paths) |
| **Flask** | `@app.route('/path', methods=[...])`, blueprint routes |
| **FastAPI** | `@app.get(...)`, `@router.post(...)`, all standard methods |
| **Express** | `app.get(...)`, `router.post(...)` with middleware chains |
| **NestJS** | `@Controller` + `@Get/@Post/...`, GraphQL `@Resolver` + `@Query/@Mutation`, `@MessagePattern`/`@EventPattern`, `@SubscribeMessage` |
| **Laravel** | `Route::get()`, `Route::resource()`, `Controller@action`, tuple syntax |
| **Drupal** | `*.routing.yml` routes (`_controller`, `_form`, entity handlers); `hook_*` implementations in `.module`/`.theme`/`.install`/`.inc` |
| **Rails** | `get '/x', to: 'users#index'`, hash-rocket `=>` syntax |
| **Spring** | `@GetMapping`, `@PostMapping`, `@RequestMapping` on methods |
| **Gin / chi / gorilla / mux** | `r.GET(...)`, `router.HandleFunc(...)` |
| **Axum / actix / Rocket** | `.route("/x", get(handler))` |
| **ASP.NET** | `[HttpGet("/x")]` attributes on action methods |
| **Vapor** | `app.get("x", use: handler)` |
| **React Router** / **SvelteKit** | Route component nodes |

## Quick Start

### 1. Run the Installer

```bash
npx @colbymchenry/codegraph
```

The installer will:
- Ask which agent(s) to configure — auto-detects installed ones from: **Claude Code**, **Cursor**, **Codex CLI**, **opencode**, **Hermes Agent**
- Prompt to install `codegraph` on your PATH (so agents can launch the MCP server)
- Ask whether configs apply to all your projects or just this one
- Write each chosen agent's MCP server config + an instructions file (e.g. `CLAUDE.md`, `.cursor/rules/codegraph.mdc`, `~/.codex/AGENTS.md`)
- Set up auto-allow permissions when Claude Code is one of the targets
- Initialize your current project (local installs only)

**Non-interactive (scripting / CI):**

```bash
codegraph install --yes # auto-detect agents, install global
codegraph install --target=cursor,claude --yes # explicit target list
codegraph install --target=auto --location=local # detected agents, project-local
codegraph install --print-config codex # print snippet, no file writes
```

| Flag | Values | Default |
|---|---|---|
| `--target` | `auto`, `all`, `none`, or csv (`claude,cursor,...`) | prompt |
| `--location` | `global`, `local` | prompt |
| `--yes` | (boolean) | prompt every step |
| `--no-permissions` | (boolean) skip Claude auto-allow list | permissions on |
| `--print-config <id>` | dump snippet for one agent and exit | — |

### 2. Restart Your Agent

Restart your agent (Claude Code / Cursor / Codex CLI / opencode / Hermes Agent) for the MCP server to load.

### 3. Initialize Projects

```bash
cd your-project
codegraph init -i
```

Builds the per-project knowledge graph index. Also wires up any project-local agent surfaces (e.g. Cursor's `.cursor/rules/codegraph.mdc`) so a single global `codegraph install` works in every project you open — no need to re-run the installer per project.

That's it — your agent will use CodeGraph tools automatically when a `.codegraph/` directory exists.

<details>
<summary><strong>Manual Setup (Alternative)</strong></summary>

**Install globally:**
```bash
npm install -g @colbymchenry/codegraph
```

**Add to `~/.claude.json`:**
```json
{
 "mcpServers": {
 "codegraph": {
 "type": "stdio",
 "command": "codegraph",
 "args": ["serve", "--mcp"]
 }
 }
}
```

**Add to `~/.claude/settings.json` (optional, for auto-allow):**
```json
{
 "permissions": {
 "allow": [
 "mcp__codegraph__codegraph_search",
 "mcp__codegraph__codegraph_context",
 "mcp__codegraph__codegraph_callers",

## CodeGraph

CodeGraph builds a semantic knowledge graph of codebases for faster, smarter code exploration.

### If `.codegraph/` exists in the project

**Answer directly with CodeGraph — don't delegate exploration to a file-reading sub-agent or a grep/read loop.** CodeGraph *is* the pre-built search index; re-deriving its answers with grep + Read repeats work it already did and costs more for the same result. For "how does X work?", architecture, trace, or where-is-X questions, answer in a handful of CodeGraph calls and stop — typically with **zero file reads**. The returned source is complete and authoritative: treat it as already read and do not re-open those files. Reach for raw Read/Grep only to confirm a specific detail CodeGraph didn't cover.

**Tool selection by intent:**

| Tool | Use For |
|------|---------|
| `codegraph_context` | Map a task / feature / area first — composes search + node + callers + callees in one call |
| `codegraph_trace` | "How does X reach Y" — the call path, each hop's body inline (follows dynamic-dispatch hops grep can't) |
| `codegraph_explore` | Survey several related symbols' source in ONE budget-capped call |
| `codegraph_search` | Find a symbol by name |
| `codegraph_callers` / `codegraph_callees` | Walk call flow one hop at a time |
| `codegraph_impact` | Check what's affected before editing |
| `codegraph_node` | Get a single symbol's source / signature |

A direct CodeGraph answer is a handful of calls; a grep/read exploration is dozens.

### If `.codegraph/` does NOT exist

At the start of a session, ask the user if they'd like to initialize CodeGraph:

"I notice this project doesn't have CodeGraph initialized. Would you like me to run `codegraph init -i` to build a code knowledge graph?"
```

</details>

## How It Works

```
┌───────────────────────────────────────────────────────────────────┐
│ Claude Code │
│ │
│ "How does a request reach the database?" │
│ calls CodeGraph tools directly — no Explore sub-agent │
│ │ │
└─────────────────────────────────┬─────────────────────────────────┘
 │
 ▼
┌───────────────────────────────────────────────────────────────────┐
│ CodeGraph MCP Server │
│ │
│ context · trace · explore · callers · callees · impact │
│ │ │
│ ▼ │
│ SQLite knowledge graph │
│ symbols · edges · files · FTS5 full-text search │
└───────────────────────────────────────────────────────────────────┘
```

1. **Extraction** — [tree-sitter](https://tree-sitter.github.io/) parses source code into ASTs. Language-specific queries extract nodes (functions, classes, methods) and edges (calls, imports, extends, implements).

2. **Storage** — Everything goes into a local SQLite database (`.codegraph/codegraph.db`) with FTS5 full-text search.

3. **Resolution** — After extraction, references are resolved: function calls → definitions, imports → source files, class inheritance, and framework-specific patterns.

4. **Auto-Sync** — The MCP server watches your project using native OS file events. Changes are debounced (2-second quiet window), filtered to source files only, and incrementally synced. The graph stays fresh as you code — no configuration needed.

---

## CLI Reference

```bash
codegraph # Run interactive installer
codegraph install # Run installer (explicit)
codegraph uninstall # Remove CodeGraph from your agents (inverse of install)
codegraph init [path] # Initialize in a project (--index to also index)
codegraph uninit [path] # Remove CodeGraph from a project (--force to skip prompt)
codegraph index [path] # Full index (--force to re-index, --quiet for less output)
codegraph sync [path] # Incremental update
codegraph status [path] # Show statistics
codegraph query <search> # Search symbols (--kind, --limit, --json)
codegraph files [path] # Show file structure (--format, --filter, --max-depth, --json)
codegraph context <task> # Build context for AI (--format, --max-nodes)
codegraph callers <symbol> # Find what calls a function/method (--limit, --json)
codegraph callees <symbol> # Find what a function/method calls (--limit, --json)
codegraph impact <symbol> # Analyze what code is affected by changing a symbol (--depth, --json)
codegraph affected [files...] # Find test files affected by changes (see below)
codegraph serve --mcp # Start MCP server
```

### `codegraph affected`

Traces import dependencies transitively to find which test files are affected by changed source files.

```bash
codegraph affected src/utils.ts src/api.ts # Pass files as arguments
git diff --name-only | codegraph affected --stdin # Pipe from git diff
codegraph affected src/auth.ts --filter "e2e/*" # Custom test file pattern
```

| Option | Description | Default |
|--------|-------------|---------|
| `--stdin` | Read file list from stdin | `false` |
| `-d, --depth <n>` | Max dependency traversal depth | `5` |
| `-f, --filter <glob>` | Custom glob to identify test files | auto-detect |
| `-j, --json` | Output as JSON | `false` |
| `-q, --quiet` | Output file paths only | `false` |

**CI/hook example:**

```bash
#!/usr/bin/env bash
AFFECTED=$(git diff --name-only HEAD | codegraph affected --stdin --quiet)
if [ -n "$AFFECTED" ]; then
 npx vitest run $AFFECTED
fi
```

---

## MCP Tools

When running as an MCP server, CodeGraph exposes these tools to Claude Code:

| Tool | Purpose |
|------|---------|
| `codegraph_search` | Find symbols by name across the codebase |
| `codegraph_context` | Build relevant code context for a task |
| `codegraph_trace` | Trace the call path between two symbols ("how does X reach Y") in one call — each hop with its body inline, following dynamic-dispatch hops (callbacks, React re-render, interface→impl) that grep can't |
| `codegraph_callers` | Find what calls a function |
| `codegraph_callees` | Find what a function calls |
| `codegraph_impact` | Analyze what code is affected by changing a symbol |
| `codegraph_node` | Get details about a specific symbol (optionally with source code) |
| `codegraph_explore` | Return source for several related symbols grouped by file, plus a relationship map, in one call |
| `codegraph_files` | Get indexed file structure (faster than filesystem scanning) |
| `codegraph_status` | Check index health and statistics |

---

## Library Usage

```typescript
import CodeGraph from '@colbymchenry/codegraph';

const cg = await CodeGraph.init('/path/to/project');
// Or: const cg = await CodeGraph.open('/path/to/project');

await cg.indexAll({
 onProgress: (p) => console.log(`${p.phase}: ${p.current}/${p.total}`)
});

const results = cg.searchNodes('UserService');
const callers = cg.getCallers(results[0].node.id);
const context = await cg.buildContext('fix login bug', { maxNodes: 20, includeCode: true, format: 'markdown' });
const impact = cg.getImpactRadius(results[0].node.id, 2);

cg.watch(); // auto-sync on file changes
cg.unwatch(); // stop watching
cg.close();
```

---

## Configuration

There isn't any — CodeGraph is zero-config. It indexes every file whose
extension maps to a [supported language](#supported-languages) and **respects
your `.gitignore`**: in git repos via git itself, and in non-git projects by
reading `.gitignore` files directly (root and nested, the same way git would).

What that means in practice:

- Anything git ignores — `node_modules`, build output, secrets in `.env` — is
 never indexed. **To keep something out of the graph, add it to `.gitignore`.**
- There's no config file to write or keep in sync, and nothing to wire up per
 language: support is automatic from the file extension.
- Files larger than 1 MB are skipped (generated bundles, minified JS, vendored
 blobs) — they cost parse budget for no useful symbols.

> Committed files that aren't gitignored *are* indexed, even under `vendor/` or a
> committed `dist/`. If you commit a dependency or build directory you don't want
> in the graph, add it to `.gitignore`.

## Supported Platforms

Every release ships a self-contained build (bundled Node runtime — nothing to
compile) for all three desktop OSes, on both Intel/AMD (x64) and ARM (arm64):

| Platform | Architectures | Install |
|----------|---------------|---------|
| Windows | x64, arm64 | PowerShell installer or npm |
| macOS | x64, arm64 | shell installer or npm |
| Linux | x64, arm64 | shell installer or npm |

See [Get Started](#get-started) for the one-line install commands.

## Supported Agents

The interactive installer auto-detects and configures each of these — wiring up
the MCP server and writing its instructions file:

- **Claude Code**
- **Cursor**
- **Codex CLI**
- **opencode**
- **Hermes Agent**

## Supported Languages

| Luau | `.luau` | Full support (everything in Lua, plus `type`/`export type` aliases, typed signatures, and Roblox instance-path `require`) |

## Troubleshooting

**"CodeGraph not initialized"** — Run `codegraph init` in your project directory first.

**Indexing is slow** — Check that `node_modules` and other large directories are excluded. Use `--quiet` to reduce output overhead.

**MCP hits `database is locked`** — current builds shouldn't: CodeGraph bundles its own Node runtime and uses Node's built-in `node:sqlite` in WAL mode, where concurrent reads never block on a writer. If you still see it:

- **You're on an old (pre-0.9) install.** Reinstall to get the bundled runtime — `curl -fsSL https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.sh | sh` (macOS/Linux), `irm https://raw.githubusercontent.com/colbymchenry/codegraph/main/install.ps1 | iex` (Windows), or `npm i -g @colbymchenry/codegraph@latest`.
- **`codegraph status` shows `Journal:` other than `wal`** — WAL couldn't be enabled on this filesystem (common on network shares and WSL2 `/mnt`), so reads can block on writes. Move the project (with its `.codegraph/` folder) onto a local disk.

**MCP server not connecting** — Ensure the project is initialized/indexed, verify the path in your MCP config, and check that `codegraph serve --mcp` works from the command line.

**Missing symbols** — The MCP server auto-syncs on save (wait a couple seconds). Run `codegraph sync` manually if needed. Check that the file's language is supported and isn't excluded by config patterns.
