Prerequisites

  • VS Code with the Cline extension 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. 
{
  "mcpServers": {
    "your-server-code": {
      "command": "npx",
      "args": ["-y", "mcp-remote@latest", "https://your-subdomain.mcpcore.io/mcp"]
    }
  }
}
For API Key mode: 
{
  "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.
