# Connecting MCP Server to VS Code
**Step 1: Register the Server**
#### Register the Server
1. Open the VS Code Command Palette (`Cmd/Ctrl + Shift + P`).
2. Type **"MCP: Add Server"**.
3. Choose **"Local server using stdio"**.
4. Enter the command: `npx -y tsx main.ts`.
5. Give it a name like `my-weather-server`.
6. Choose **local setup**.
This creates a `.vscode/mcp.json` file in your project:
```json
{
"inputs": [],
"servers": {
"my-weather-server": {
"type": "stdio",
"command": "npx",
"args": [
"-y",
"tsx",
"main.ts"
]
}
}
}
```
**Step 2: Test with GitHub Copilot**
1. Start the server by clicking the "Start" button next to your server name in the MCP panel.
2. Switch to **Agent Mode** in the Copilot sidebar.
3. Ask: "What's the weather like in Tokyo?"
You should see a prompt in Copilot asking if it can run the `get-weather` tool with the input `{ city: "Tokyo" }`. Confirm the prompt to proceed.
**Expected Result:**
Instead of raw JSON, you should see a beautifully formatted weather report, such as:
```md
> **Weather in Tokyo Today**
> **Temperature:** 28°C (feels like 32°C)
> **Humidity:** 75%
> **Conditions:** Partly cloudy with light rain expected in the evening
```
This demonstrates how seamlessly MCP servers integrate with AI tools like GitHub Copilot.
