MCP Server Example

This project is a very basic MCP server ready to be consumed by Cursor or other tools.

Modify index.ts and add any tools you want, or keep the default ones.

Then build the project:

pnpm run build

And run it:

pnpm run start

Now add a .cursor/mcp.json file in your project, and paste the following;

{
    "mcpServers":{
        "weather":{
            "command": "node",
            "args": ["[path]/build/index.js"]
        }     
    }
}

Replace [path] with the absolute path to this project. Run pwd in the project folder for that. For example, in my case it is:

{
    "mcpServers":{
        "weather":{
            "command": "node",
            "args": ["/Users/ivanbtrujillo/Development/mcp-server-spike/build/index.js"]
        }     
    }
}

Now go to "Settings" in cursor. You should be able to see the MCP server there. Enable it (click on the top right) MCP Server Cursor

Now go to the chat, switch to Agent mode and select claude-3.7-sonnet as your model.

Type the following:

What is the weather in Texas?

It will use the MCP to get first the weather alerts, and then the forecast Here is an example of how the chat interface looks when querying the weather in Texas:

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
