# VS Code

> Connect your MCPCore server to VS Code using the native MCP HTTP transport.

## Prerequisites

* [VS Code](https://code.visualstudio.com) with MCP support (VS Code 1.99+)
* A MCPCore server with at least one tool
* The config snippet from your server's **Integration** tab

***

## Step 1 — Get your config snippet

Open your server's detail page, click the **Integration** tab, and select **VS Code**. Copy the generated snippet.

VS Code uses a `servers` key (not `mcpServers`) and a `type: "http"` field:

```json theme={null}
{
  "servers": {
    "your-server-code": {
      "type": "http",
      "url": "https://your-subdomain.mcpcore.io/mcp"
    }
  }
}
```

For API Key mode:

```json theme={null}
{
  "servers": {
    "your-server-code": {
      "type": "http",
      "url": "https://your-subdomain.mcpcore.io/mcp",
      "headers": {
        "Authorization": "Bearer <your-api-key>"
      }
    }
  }
}
```

***

## Step 2 — Add to your workspace config

Create or open `.vscode/mcp.json` in your workspace root and paste the snippet:

```
your-project/
└── .vscode/
    └── mcp.json    ← create this file
```

If you want the server available across all workspaces, add it to your VS Code User Settings instead:

1. Open Command Palette (`Cmd+Shift+P` / `Ctrl+Shift+P`)
2. Search for **Preferences: Open User Settings (JSON)**
3. Add the `servers` block at the top level

***

## Step 3 — Reload VS Code

Save the config file. VS Code picks up MCP configuration changes automatically — you may need to open a new chat to see the updated tools.

***

## Step 4 — Verify

Open **Copilot Chat** or **Agent mode** in VS Code and reference one of your tools. Your MCPCore tools are available in any AI-powered feature.

## Troubleshooting

| Problem             | Solution                                                                   |
| ------------------- | -------------------------------------------------------------------------- |
| Tools not appearing | Ensure VS Code 1.99+ and that the `servers` key (not `mcpServers`) is used |
| `401 Unauthorized`  | Verify the `Authorization` header value                                    |
| JSON parse error    | Validate `.vscode/mcp.json` syntax                                         |
| Tool calls fail     | Check [Traffic Logs](/observability/traffic-logs)                          |
