- Python 3.11+
- [uv](https://docs.astral.sh/uv/) (recommended) or pip

### **Installation Steps**

```bash
# Clone the repository
git clone <repository-url>
cd augments-mcp-server

# Install with uv (recommended)
uv sync

# Or install with pip
pip install -e .
```

### **Environment Configuration**

Create a `.env` file for optional configuration:

```

## 🚀 Usage

### **Option 1: Hosted MCP Server (Recommended)**

For the easiest setup, connect directly to our hosted MCP server at `https://mcp.augments.dev/mcp`. No installation required!

#### **Using Claude Code CLI**

```bash
# Add the hosted MCP server
claude mcp add --transport http augments https://mcp.augments.dev/mcp

# Verify the server is configured
claude mcp list

# Get server details
claude mcp get augments
```

#### **Using Cursor**

Add to your Cursor MCP configuration:

```json
{
  "mcpServers": {
    "augments": {
      "transport": "http",
      "url": "https://mcp.augments.dev/mcp"
    }
  }
}
```

#### **Manual Configuration (Claude Desktop)**

Add to your Claude Desktop MCP configuration file:

**Location**: 
- **macOS**: `~/Library/Application Support/Claude/claude_desktop_config.json`
- **Windows**: `%APPDATA%\Claude\claude_desktop_config.json`
- **Linux**: `~/.config/Claude/claude_desktop_config.json`

```json
{
  "mcpServers": {
    "augments": {
      "transport": {
        "type": "streamable-http",
        "url": "https://mcp.augments.dev/mcp"
      }
    }
  }
}
```

#### **Using the Hosted Server**

Once configured, you can access all framework documentation directly:

1. **Access Framework Documentation**:
   ```
   @augments list frameworks in the web category
   @augments get documentation for tailwindcss responsive design
   ```

2. **Get Multi-Framework Context**:
   ```
   @augments get context for nextjs, tailwindcss, and shadcn-ui 
   for building a dashboard with dark mode
   ```

3. **Analyze Code Compatibility**:
   ```
   @augments analyze this React component for tailwindcss compatibility:
   [paste your code]
   ```

4. **Search Documentation**:
   ```
   @augments search nextjs documentation for "app router"
   ```

The hosted server provides:
- ✅ **No installation required** - Works immediately
- ✅ **Always up-to-date** - Latest framework documentation
- ✅ **High availability** - Reliable uptime with smart caching
- ✅ **No authentication** - Completely frictionless access
- ✅ **Rate limiting protection** - Intelligent abuse prevention
- ✅ **MCP Protocol Compliant** - Uses official MCP Python SDK with streamable-http transport
- ✅ **Multi-Client Support** - Compatible with Claude Code, Cursor, and other MCP clients

### **Option 2: Local Installation**

For development, customization, or offline use, you can run the server locally.

#### **Starting the Local Server**

```bash
# Run with uv (recommended)
uv run augments-mcp-server

# Or run directly
python -m augments_mcp.server

# Development mode with auto-reload
uv run fastmcp dev src/augments_mcp/server.py
```

#### **Claude Code Integration (Local)**

##### **Method 1: Using Claude Code CLI (Recommended)**

```bash
# Add the local MCP server with environment variables
claude mcp add augments-local -e AUGMENTS_CACHE_DIR="~/.cache/augments-mcp-server" -e GITHUB_TOKEN="your_github_token" -- uv run augments-mcp-server

# Verify the server is configured
claude mcp list

# Get server details
claude mcp get augments-local
```

##### **Method 2: Manual Configuration**

```json
{
  "mcpServers": {
    "augments-local": {
      "command": "uv",
      "args": ["run", "augments-mcp-server"],
      "cwd": "/path/to/augments-mcp-server",
      "env": {
        "AUGMENTS_CACHE_DIR": "~/.cache/augments-mcp-server",
        "GITHUB_TOKEN": "your_github_token"
      }
    }
  }
}
```

##### **Method 3: Global Configuration**

```bash
# Add with full path to project directory
claude mcp add augments-local -e GITHUB_TOKEN="your_github_token" -- uv run --directory /path/to/augments-mcp-server augments-mcp-server
```

#### **Server Management**

```bash
# List all configured MCP servers
claude mcp list

# Get details for a specific server
claude mcp get augments

# Remove the server if needed
claude mcp remove augments

# Update server configuration (remove and re-add)
claude mcp remove augments
claude mcp add --transport http augments https://mcp.augments.dev/mcp
```

#### **Troubleshooting**

- **Server not appearing**: Restart Claude Code after configuration
- **Connection errors**: For hosted server, check internet connection. For local server, verify installation
- **Environment issues**: Only applies to local installations
- **Permission errors**: Ensure Claude Code has network access (hosted) or file access (local)
