Instalabsai Instagit Analyze Git Repo

Analyze Git Repo

Analyze any Git repository in depth — understand architecture, surface real APIs, debug across repo boundaries, and get source citations with exact file paths and line numbers. Powered by Instagit.

Quick Start

Add to MCP client configuration:

{
  "mcpServers": {
    "instagit": {
      "command": "npx",
      "args": ["-y", "instagit@latest"]
    }
  }
}

No API key required — auto-registers anonymous token on first use. Requires Node.js 18+.

For higher rate limits, sign up at instagit.com and add an API key:

{
  "mcpServers": {
    "instagit": {
      "command": "npx",
      "args": ["-y", "instagit@latest"],
      "env": {
        "INSTAGIT_API_KEY": "ig_your_api_key_here"
      }
    }
  }
}

Works with Claude Code, Claude Desktop, Cursor, VS Code, and any MCP-compatible client.

Tool: ask_repo

Analyze any Git repository with AI.

Prompting Examples

For detailed examples across architecture, integration, debugging, migration, security, and code quality — see references/examples.md.

Key patterns:

repo: "nginx/nginx"
prompt: "How does nginx handle thousands of concurrent connections with its event-driven architecture? Walk through the event loop, worker process model, and connection state transitions."

repo: "hashicorp/terraform"
prompt: "How do I implement a custom Terraform provider from scratch? What interfaces does the SDK expose, how are CRUD operations mapped to the resource lifecycle, and how does schema definition work?"

repo: "ggml-org/llama.cpp"
prompt: "How does llama.cpp's KV cache work during autoregressive generation? How are past key-value pairs stored, reused across tokens, and evicted when the context window fills up?"

Configuration

Anonymous tokens stored in ~/.instagit/token.json.
