Gotchas

Claude Desktop reads MCP servers from an "mcpServers" object, but the config file is stdio-only: it cannot dial a remote URL directly. To reach a remote server you bridge it locally by running "npx mcp-remote <url>" as the command. Native remote Connectors exist on paid plans, but not through this config file, so the bridge is the portable path.
