Tenzo MCP Server

Ensure Tenzo is added as a connector

Tenzo is a custom connector. If you don't see it in your list, ask an admin to add it from claude.ai/admin-settings/connectors, pointing at https://ai.gotenzo.com/mcp.

Open Settings

In Claude Desktop, open Settings and navigate to the Connectors section.

Connect Tenzo

Find Tenzo in the list and click Connect.

Authorize

A browser window will open for you to sign in with your Tenzo account. Once authorized, return to Claude Desktop.

Start chatting

Open a new conversation and ask about your restaurant data. You should see the Tenzo tools available in the tools menu.

Add the server

Run the following command in your terminal:

claude mcp add --transport http tenzo https://ai.gotenzo.com/mcp/

Start chatting

Start a new conversation and ask something like "What were my sales last week?". You'll be prompted to authorize via OAuth on first use.

Install the Tenzo app for ChatGPT

Please install the ChatGPT plugin from here.

Authorize

You'll be prompted to connect your Tenzo account on first use.

Open your settings file

Edit ~/.gemini/settings.json (create it if it doesn't exist).

Add the Tenzo MCP server

{
  "mcpServers": {
    "tenzo": {
      "url": "https://ai.gotenzo.com/mcp"
    }
  }
}

Start a conversation

Launch the Gemini CLI and ask a question about your restaurants. You'll be prompted to authorize via OAuth on first use.

Clear the two gates

Override the org policy that blocks custom-MCP data stores: IAM & Admin → Organization Policies, set it to Off for your project (this is org-level, so it needs an Organization Policy Administrator). Then grant the builder the Discovery Engine Editor role (roles/discoveryengine.editor).

Create the Tenzo credentials

Gemini can't self-register, so Tenzo registers an OAuth client for you using the redirect URI https://vertexaisearch.cloud.google.com/oauth-redirect, and provides the client ID and client secret. Getting this redirect URI right is what makes sign-in work later.

Create the data store

Go to Data stores → Custom MCP Server. Set the server URL to https://ai.gotenzo.com/mcp, then paste the authorization URL, token URL and the client ID/secret from the previous step. Sign in and wait for the state to flip to Active.

Enable the tools

In the data store, choose Actions → Reload custom actions, pick the Tenzo tools you want, then Enable actions. Skip this and the connector is attached but does nothing.

Attach it to your Gemini app

Go to Apps → your app → Add existing data stores and select Tenzo. Then open the app, go to Manage your data → Enable actions, and sign in to authorise. The Tenzo tools are now callable in that app.
