Usage

Update api/server.ts with your tools, prompts, and resources following the MCP TypeScript SDK documentation.

There is also a Next.js version of this template

MCP Client Integration

When adding this server to an MCP client application, use your deployment URL followed by /mcp:

https://your-deployment-url.vercel.app/mcp

Example Tools

The template includes two example tools to get you started:

roll_dice - Rolls an N-sided die (minimum 2 sides)
get_weather - Gets current weather data (via an API) for a location using latitude, longitude, and city name

These tools demonstrate basic functionality and API integration patterns. Replace them with your own tools.
