This PR consists of two changes:
--client-config=cursor), and updates the tip message to include Cursor instructions.teleport_list_databasesfunction (MCP DB) to return text instead of embedded resources so Cursor can use this function. Cursor completely removed support for MCP resources, and any tool that returns its type is not parsed and returns an error. This change doesn't affect the server functionality, and other clients (like Claude Desktop) should have the same behavior.For reviewers: Given that Cursor and Claude Desktop use the same configuration format, I've added small helper functions for Cursor (instead of duplicating or moving the implementation to a shared package).
Note: Cursor MCP deeplinks generation wasn't added as hyperlinks on terminals might not be the best UX. The links would probably be available on WebUI.
