## Quick Start

### 🚀 Using npx (Recommended & Tested)

**No installation required!** Just add this configuration to your MCP client:

```json
{
  "mcpServers": {
    "context-engine": {
      "command": "npx",
      "args": ["-y", "context-engine-mcp"]
    }
  }
}
```

### Alternative: Global Installation

1. **Install globally:**

   ```bash
   npm install -g context-engine-mcp
   ```

2. **Configure your MCP client:**

   ```json
   {
     "mcpServers": {
       "context-engine": {
         "command": "context-engine-mcp"
       }
     }
   }
   ```

### Local Development

1. **Clone and build:**

   ```bash
   git clone https://github.com/RaheesAhmed/Context-Engine-MCP-Server.git
   cd Context-Engine-MCP-Server
   npm install
   npm run build
   ```

2. **Configure with local path:**
   ```json
   {
     "mcpServers": {
       "context-engine": {
         "command": "node",
         "args": ["./dist/index.js"]
       }
     }
   }
   ```
