**Integrate Bazel with AI coding assistants via the Model Context Protocol**

bazel-mcp is a [Model Context Protocol](https://modelcontextprotocol.io/) server that exposes your Bazel workspace to AI assistants like Claude (in VS Code or Cursor). It enables AI assistants to understand and work with Bazel projects by providing direct access to build, test, run, and query capabilities.

## Why bazel-mcp?

- **🤖 AI-Native Development**: Let AI assistants build, test, and run Bazel targets directly
- **📦 Zero Configuration**: Automatically discovers all Bazel targets in your workspace
- **🔄 Real-time Streaming**: See build and test output as it happens
- **🎯 Smart Context**: AI understands your build graph and dependencies
- **⚡ Fast Iteration**: No context switching between AI chat and terminal

## Installation

### From PyPI (Recommended)

```bash
pip install bazel-mcp
```

### From Source

```bash
git clone https://github.com/sandeepnmenon/py_bazel_mcp
cd py_bazel_mcp
pip install -e .
```

## Quick Start

### 1. Configure Your Editor

#### VS Code (Claude Extension)

Create `.vscode/mcp.json` in your workspace:

```json
{
  "mcpServers": {
    "bazel-mcp": {
      "command": "bazel-mcp",
      "args": ["--repo", "${workspaceFolder}"]
    }
  }
}
```

#### Cursor

Add as a custom MCP server:
1. Settings → MCP Servers → Add Custom Server
2. Command: `bazel-mcp`
3. Args: `--repo /path/to/your/bazel/workspace`

### 2. Verify Setup

Ask your AI assistant:
> "Can you list all Bazel targets in this workspace?"

The assistant should use the `bazel_list_targets`…
