Can I send an email with HTML content and track whether it was delivered?

Absolutely. Use the `send_email` tool with your HTML body, then use `get_email` with the returned ID to check delivery status, open events, and bounce details in real time.

How do I check if my sending domain DNS records are correctly configured?

Run `list_domains` to find your domain ID, then use `get_domain` to inspect the full DNS record set (SPF, DKIM, return path). If records are pending, trigger `verify_domain` to re-check.

Can I add subscribers to an audience for broadcast campaigns?

Yes. First use `list_audiences` to get the target audience ID, then call `create_contact` with the subscriber's email and optional name fields. The contact is immediately available for broadcast targeting.

Resend + Claude Desktop FAQ

Common questions about integrating Resend 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.
