How to add Postmark to Cursor

Open Cursor Settings → MCP and add a new server, or edit ~/.cursor/mcp.json (or .cursor/mcp.json in a project).
Paste the remote URL, or the install config from the server page for a local server.
Sign in if the server asks, then use it in Agent chat.

Example for Postmark (from the table above):

{
  "mcpServers": {
    "postmark": {
      "url": "https://gateway.pipeworx.io/postmark/mcp"
    }
  }
}

Menus change, so check Cursor's MCP docs. Every server page has a copy-paste config for Cursor.

Is it safe to connect Postmark to Cursor?

Use the official server run by ActiveCampaign (Postmark). Anything a tool returns is sent to the AI vendor, so use a business plan that doesn't train on your data.
