🚀 Stop Wasting Tokens. Start Coding Faster.

Code-Knowledge-Graph is a high-performance, local indexing engine that maps your codebase into a structured graph. It allows AI agents to understand your project instantly without exhaustive file crawling.

✨ Key Features

• 🏗️ Graph-Based Indexing: Transforms flat files into a rich semantic network of classes, functions, and dependencies.
• 📉 Token Optimization: Drastically reduces the "context window tax" by providing surgical code snippets instead of full-file dumps.
• ⚡ Zero Latency: 100% local processing. No API calls required for indexing.
• 🤖 Agent Ready: Native support for Claude Code, Codex, Cursor, OpenCode, and Hermes Agent.
• 🛡️ Privacy First: Your code never leaves your machine.

📽️ Demo

Example: Rapidly mapping a 100k LOC repository in seconds.

🧩 Agent Compatibility

| Agent | Support Level | Integration Method | | :--- | :---: | :--- | | Claude Code | 💎 Full | Custom Tool / Hook | | Cursor | ✅ Native | .cursorrules / Indexing | | Codex | ✅ High | Plugin | | OpenCode | 🛠️ Beta | API Bridge | | Hermes Agent | 🚀 Optimized | Native Protocol |

🛠️ Quick Start

1. Installation

# Clone the repository
git clone https://github.com/ishandutta2007/Code-Knowledge-Graph.git

# Navigate to the directory
cd Code-Knowledge-Graph

# Install dependencies
npm install

2. Index your codebase

npm run ckg -- index ./path/to/your/project

3. Query the graph

npm run ckg -- query SymbolName

4. Run the MCP Server

To use this with Claude Code or other MCP-compatible agents:

npm run mcp

Then add it to your agent's config (e.g., in claude_desktop_config.json):

{
  "mcpServers": {
    "code-knowledge-graph": {
      "command": "node",
      "args": ["--loader", "ts-node/esm", "C:/path/to/Code-Knowledge-Graph/src/index.ts", "mcp"],
      "cwd": "C:/path/to/Code-Knowledge-Graph"
    }
  }
}

📈 Why Code Knowledge Graph?

Traditional AI agents spend ~40% of their tokens just trying to find where a function is defined. By providing a pre-indexed graph, we flip the script:

| Metric | Without CKG | With CKG | Improvement | | :--- | :--- | :--- | :--- | | Initial Context Load | 15,000 Tokens | 1,200 Tokens | 92% Reduction | | Tool Call Latency | 5-10s |

Built with ❤️ for the AI Engineering Community.
