💻 Usage Examples

Testing with MCP Inspector

You can test the server locally using the MCP Inspector tool:

1. Build the server:

   npm run build
   

2. Run the server with the MCP Inspector:

   # Make sure to specify the full path to the built file
   npx @modelcontextprotocol/inspector node ./build/index.js
   

The inspector will open in your browser and connect to the server via stdio transport. You can:

• View available tools
• Test chat completion with different parameters
• Debug server responses
• Monitor server performance

⚠️ Important Note

The server uses the DeepSeek R1 model (deepseek-reasoner) by default, which offers state-of-the-art performance for inference and general tasks.
