# Cline

> Connect your MCPCore server to the Cline VS Code extension.

## Prerequisites

* [VS Code](https://code.visualstudio.com) with the [Cline extension](https://marketplace.visualstudio.com/items?itemName=saoudrizwan.claude-dev) installed
* 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 **Cline**. Copy the generated snippet.

```json theme={null}
{
  "mcpServers": {
    "your-server-code": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://your-subdomain.mcpcore.io/mcp"]
    }
  }
}
```

For API Key mode:

```json theme={null}
{
  "mcpServers": {
    "your-server-code": {
      "command": "npx",
      "args": [
        "-y", "mcp-remote@latest",
        "https://your-subdomain.mcpcore.io/mcp",
        "--header", "Authorization: Bearer <your-api-key>"
      ]
    }
  }
}
```

***

## Step 2 — Open Cline's MCP config

In VS Code, open the Cline extension panel (sidebar icon or Command Palette → **Cline: Open**).

Navigate to **MCP Servers** and click **Configure MCP Servers**. This opens Cline's `mcp_settings.json` file.

***

## Step 3 — Merge the snippet

Add your server entry to the `mcpServers` object in `mcp_settings.json`.

***

## Step 4 — Save and verify

Save the file. Cline reloads MCP servers automatically. Your MCPCore tools will appear in the Cline MCP Servers list with a green status indicator.
