How do I create a Resend API Key?

Log in to the [**Resend Dashboard**](https://resend.com/api-keys), go to **Settings > API Keys**, click **Create API Key**, select the permission scope (Full Access, Sending, or Domains), give it a name and copy the key immediately — it starts with `re_` and won't be shown again.

Can I send HTML emails with attachments?

Yes! Use the `send_email` tool with the `html` parameter for HTML body content and optionally include attachments. You can also provide a `text` fallback for email clients that don't render HTML. Attachments are passed as objects with filename, content (base64) and content_type.

How do I verify a domain for sending?

Use `create_domain` with your domain name (e.g. "example.com"). Resend will return the SPF and DKIM DNS records you need to add to your DNS provider. After adding the records, use `verify_domain` with the domain ID to trigger re-verification. The domain status will change to "verified" once DNS propagation is complete.

What are the API rate limits?

Resend allows 5 requests per second per team, shared across all API keys. If you exceed this limit, you'll receive a 429 response. Rate limits can be increased by contacting Resend support for verified senders.

Resend Alternative + Cursor FAQ

Common questions about integrating Resend Alternative MCP Server with Cursor.

What is Agent mode and why does it matter for MCP?

Agent mode is Cursor's autonomous execution mode where the AI can perform multi-step tasks: reading files, editing code, running terminal commands, and calling MCP tools. Without Agent mode, Cursor operates in a simpler ask-and-answer mode that doesn't support tool calling. Always ensure you're in Agent mode when working with MCP servers.

Where does Cursor store MCP configuration?

Cursor looks for MCP server configurations in a mcp.json file. You can configure servers at the project level (.cursor/mcp.json in your project root) or globally (~/.cursor/mcp.json). Project-level configs take precedence.

Can Cursor use MCP tools in inline edits?

No. MCP tools are only available in Agent mode through the chat panel. Inline completions and Tab suggestions do not trigger MCP tool calls. This is by design — tool calls require user visibility and approval.

How do I verify MCP tools are loaded?

Open Settings → Features → MCP and look for your server name. A green indicator means the server is connected. You can also check Agent mode's available tools by clicking the tools dropdown in the chat panel.
