How does Notesnook ensure my notes remain private through the agent?

Notesnook uses end-to-end encryption (E2EE). When your agent uses the `create_note` or `get_note` tools, it handles encrypted envelopes. This ensures that only authorized clients with your keys can decrypt the actual text body, maintaining zero-knowledge security natively.

Can I see all my notebooks and tags using my agent?

Yes. Use the `list_notebooks` and `list_tags` tools to retrieve the organizational hierarchy of your vault. Your agent will report the names and IDs, helping you understand how your encrypted information is classified across your account.

How do I trigger a synchronization between my vault and the server?

The `sync_items` tool allows your agent to initiate a full or incremental state resolution. By providing a Unix timestamp, your agent can fetch only the most recent encrypted binary objects, ensuring your local environment matches the server's state.

Notesnook (Private Note Taking & E2EE) + Claude Desktop FAQ

Common questions about integrating Notesnook (Private Note Taking & E2EE) MCP Server with Claude Desktop.

How does Claude Desktop discover MCP tools?

When Claude Desktop starts, it reads the claude_desktop_config.json file and connects to each configured MCP server. It calls the tools/list endpoint to fetch the schema for every available tool, then surfaces them as clickable options in the chat interface via the 🔌 icon.

What happens if the MCP server is temporarily unavailable?

Claude Desktop handles disconnections gracefully. if the server is unreachable at startup, the tools simply won't appear. Once the server becomes available again, restarting Claude Desktop will re-establish the connection. There is no timeout penalty or error loop.

Can I connect multiple MCP servers simultaneously?

Yes. You can add as many servers as you need in the mcpServers section of the config file. Each server appears as a separate tool provider, and Claude can use tools from multiple servers in a single conversation turn.

Is there a limit on the number of tools per server?

Claude Desktop can handle hundreds of tools per server. However, for optimal LLM performance, Vinkius servers are designed to expose focused, well-documented tool sets rather than overwhelming the model with too many options.

Does Claude Desktop support Streamable HTTP transport?

Yes. Claude Desktop supports both SSE (Server-Sent Events) and the newer Streamable HTTP transport that Vinkius uses. Simply provide the server URL. Claude auto-negotiates the transport protocol.
