Add the Resend MCP server to VS Code

Prerequisites

• VS Code installed.
• RESEND_API_KEY — Your Resend API key (required for stdio mode; optional in HTTP mode where clients pass it as a bearer token).

Setup

{
  "servers": {
    "resend": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "resend-mcp"
      ],
      "env": {
        "RESEND_API_KEY": "<RESEND_API_KEY>",
        "SENDER_EMAIL_ADDRESS": "<SENDER_EMAIL_ADDRESS>",
        "REPLY_TO_EMAIL_ADDRESSES": "<REPLY_TO_EMAIL_ADDRESSES>"
      }
    }
  }
}

Gotchas

• VS Code uses the `servers` key (not `mcpServers`) and requires `type`.

VS Code is the exception to every other client: its top-level key is "servers", not "mcpServers", and each entry needs an explicit "type" (for example "http" or "stdio"). Secrets are not inlined; instead you declare an "inputs" array and reference each value as ${input:id}, so VS Code prompts for it once and never writes it to disk. Remote servers connect natively with OAuth.
