For Copilot's own MCP client, add templates/vscode-mcp.json as a user or workspace MCP config:
{
"servers": {
"agentstack": {
"type": "http",
"url": "https://agentstack.tech/mcp"
}
}
}type must be http. VS Code then uses the remote Streamable HTTP server. Sign in when the editor opens OAuth. Do not point this entry at a local command.
