Natural’s production and sandbox MCP servers now support MCP 2026-07-28 and Client ID Metadata Documents (CIMD). This expands compatibility with ChatGPT, Claude Code, Codex, Cursor, and other compatible MCP clients. CIMD lets compatible clients connect without manual registration. Command-line clients can also use temporary localhost callback ports. Existing MCP connections continue to work. Connect your client in the MCP guide.
