[Feature] Hosted MCP endpoint for ZenNotes Cloud #948

Problem

The existing MCP integration requires running a local or self-hosted server, making it difficult for remote MCP clients and AI agents to connect directly to ZenNotes Cloud vaults.

Proposed solution

Expose a hosted MCP endpoint for ZenNotes Cloud that reuses the existing MCP functionality, with secure authentication (ideally OAuth).

This would enable remote access without hosting or exposing a local server, while preserving existing security guarantees, including E2EE where supported.
