# 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](https://instagit.com).

## Quick Start

Add to MCP client configuration:

```json
{
  "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](https://instagit.com) and add an API key:

```json
{
  "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.

| Parameter | Type     | Required | Description                                                    |
|-----------|----------|----------|----------------------------------------------------------------|
| `repo`    | string   | yes      | Repository URL, shorthand (`owner/repo`), or any public Git URL |
| `prompt`  | string   | yes      | What to analyze or ask about the codebase                      |
| `ref`     | string   | no       | Branch, commit SHA, or tag (default: repo's default branch)    |

## Prompting Examples

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

| Variable            | Description                                          | Default                      |
|---------------------|------------------------------------------------------|------------------------------|
| `INSTAGIT_API_KEY`  | API key from [instagit.com](https://instagit.com)    | Auto-registers anonymous token |
| `INSTAGIT_API_URL`  | Custom API endpoint                                  | Production API               |

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