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 + VS Code Copilot FAQ

Common questions about integrating Resend Alternative MCP Server with VS Code Copilot.

Which VS Code version supports MCP?

MCP support requires VS Code 1.99 or later with the GitHub Copilot extension. Ensure both are updated to the latest version. Older versions of Copilot may not expose the Agent mode toggle.

How do I switch to Agent mode?

Open the Copilot Chat panel and look for two mode options: "Ask" and "Agent". Click "Agent" to enable autonomous tool calling. In Ask mode, Copilot provides conversational answers but cannot invoke MCP tools.

Can I restrict which MCP tools Copilot can access?

Yes. VS Code shows a tool consent dialog before any MCP tool is invoked for the first time. You can also configure tool access policies at the organization level through GitHub Copilot settings.

Does MCP work in VS Code Remote or Codespaces?

Yes. MCP servers configured via .vscode/mcp.json work in Remote SSH, WSL, and GitHub Codespaces environments. The MCP connection is established from the remote host, so ensure the server URL is accessible from that environment.
