How to add Substack 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 Substack by Cotlet (from the table above):

{
  "mcpServers": {
    "substack": {
      "url": "https://cotlet.dev/mcp/v1/substack/connect"
    }
  }
}

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

Is it safe to connect Substack to Cursor?

Check the publisher and trust grade first. Substack doesn't run an official MCP server we can verify, so every server here comes from a third party and can see whatever your account can.
