Add a remote MCP server to VS Code (GitHub Copilot)

How VS Code (GitHub Copilot) connects to a remote (Streamable HTTP) MCP server, and the ready config for each of 29 CyberMax servers.

The format

• .vscode/mcp.json in your workspace (VS Code format, top-level "servers")
• or the portable .mcp.json at the workspace root (top-level "mcpServers")

Example with the Afterwren server:

Add to .vscode/mcp.json:

{
  "servers": {
    "afterwren": {
      "type": "http",
      "url": "https://afterwren.cybermaxtools.com/mcp?via=use-with-vs-code"
    }
  }
}

With a paid key:

{
  "inputs": [
    {
      "type": "promptString",
      "id": "cybermax-key",
      "description": "CyberMax API key",
      "password": true
    }
  ],
  "servers": {
    "afterwren": {
      "type": "http",
      "url": "https://afterwren.cybermaxtools.com/mcp?via=use-with-vs-code",
      "headers": {
        "x-api-key": "${input:cybermax-key}"
      }
    }
  }
}

• In .vscode/mcp.json the key is "servers" and "type": "http" is required.
• The docs note the Add Server flow now recommends the portable .mcp.json, which uses "mcpServers" instead; both formats are documented.
