Setting Up the Reteno MCP Server in Cursor

Cursor connects directly to your Reteno account through the Reteno MCP (Model Context Protocol) server. Once connected, you can manage email templates, contacts, segments, events, and analytics from Cursor, without opening the Reteno platform.

For a full list of what the agent can do, see Integrating Reteno with AI Agents. For the server endpoint, authentication, and the full list of tools, see the Reteno MCP Server reference.

Requirements

• An active Reteno account
• A current version of Cursor (remote MCP support is built in)

Add the Reteno MCP Server

1. In Cursor, open Settings → Tools & MCPs.
2. Click Add Custom MCP.

3. Cursor opens the mcp.json configuration file. Add the Reteno server:

{
  "mcpServers": {
    "reteno": {
      "url": "https://mcp.reteno.com"
    }
  }
}

4. Save the file (Ctrl+S, or ⌘S on macOS).
5. Restart Cursor.
6. After the restart, open Settings → Tools & MCPs again and click Connect next to the Reteno server.
7. Sign in with your Reteno account and grant access.

That's it — no extra configuration is needed. The agent acts with your Reteno account's permissions and can read your account data, including contact personal data.

Cursor supports remote MCP servers configured with a url in mcp.json. For more, see Cursor's MCP documentation.

Verify the Connection

Ask Cursor to list what it can do, for example:

List the available Reteno MCP tools.

If the connection works, Cursor returns the Reteno tools grouped by area (contacts, segments, events, templates, analytics, and more). The first time the agent runs a tool, Cursor asks you to approve the tool call.

Troubleshooting

• The server doesn't appear after restarting — check that mcp.json is valid JSON (no trailing commas or missing brackets), then reopen Settings → Tools & MCPs and click Connect.
• Sign-in doesn't complete — click Connect again and finish signing in the browser window; make sure pop-ups aren't blocked.
• No tools are listed — confirm the Reteno server shows as connected and enabled, and that your Reteno account has the access rights for the tools you need.
• To see what's happening — open Cursor's MCP logs (in the Output panel) to view connection and tool-call details.
