What Gemini needs to operate SmartChat.

Google describes several ways to connect an MCP server to Gemini. The same basic principle applies to all of them, and it starts with the address of the server.

  1. Server address

    Gemini needs the HTTPS address of the SmartChat MCP server. For this, Google names remote servers with Streamable HTTP.

    HTTPS

  2. Sign-in with OAuth

    SmartChat signs you in with OAuth and shows a consent page where you choose the permissions.

    OAuth

  3. Approve actions

    Which tools Gemini may use, you control on Google's side, depending on the way for example with a list of allowed tools.

    Approval

  4. Confirm and start

    Google has actions that change data confirmed by default. Then you describe the automation.

    Confirmation

Three ways to add an MCP server in Gemini.

All three come from the public Google documentation. You replace the placeholders with your own details.

  • { "type": "mcp_server", "name": "smartchat", "url": "<Adresse des MCP-Servers>" }

    Gemini API

    For developers: the server is listed as a tool in the call. Google does not accept SSE servers here.

  • gemini mcp add --transport http smartchat <Adresse des MCP-Servers> /mcp auth smartchat

    Gemini CLI

    For the command line: one command adds the server, then you sign in with /mcp auth.

  • Apps > Connected Data Stores > New data store > Custom MCP Server > Add MCP server

    Gemini Enterprise

    For organizations: an administrator creates a Custom MCP Server under Connected Data Stores.

Three businesses, three automations on WhatsApp.

You describe the goal in Gemini, SmartChat sends the message. This is how your contact reads the result.

One day before the appointment, the reminder arrives.

Time, documents and parking are in the message.

Anyone who writes the word receives all the details about the voucher.

This is how you phrase the request.

Gemini passes your goal on to SmartChat. The clearer the trigger, timing and content are in the sentence, the more exact the automation will be.

  1. 1

    Name the trigger

    When should the automation start?

    Start the automation as soon as someone signs up through the popup on our website.
  2. 2

    Describe the message

    What should be in the text?

    The WhatsApp message should say thank you, give the opening hours and invite to the café.
  3. 3

    Set the timing

    When does it go out?

    Send it the next morning at 9 am.

Your contact sees WhatsApp, not Gemini.

  • A completely normal message

    Contacts cannot tell which assistant you used to create the automation.

  • Templates only

    Outside the inbox, messages go out as a template that Meta has approved.

  • Replies in the inbox

    Follow-up questions land in the inbox, where you continue the conversation.

After the confirmation comes the class schedule.

When a contact confirms their signup, the automation can immediately send the class schedule and the most important details.

  • Trigger: opt-in

    The changed opt-in status starts the flow.

  • Content as you wish

    You set the class schedule, opening hours or prices in the instruction.

  • No waiting

    The automation runs as soon as the trigger occurs.

Plan messages, without and with automation.

Organized by hand

  • You explain vouchers, classes and consultations from scratch every time.
  • Whoever signs up waits for a reply.
  • Reminders happen spontaneously or not at all.
  • The texts sit in notes and old chats.

With Gemini and SmartChat

  • You describe the flow once in Gemini.
  • SmartChat sends it in WhatsApp the same way every time.
  • Deleting and plan actions stay blocked, so you keep control.
  • You see replies in the inbox.

Frequently asked questions about Gemini and SmartChat.

How do I connect Gemini to SmartChat?

Google describes three ways for MCP servers: the Gemini API, the Gemini CLI and Gemini Enterprise. In each one you enter the address of the SmartChat MCP server and sign in with OAuth.

Does this also work in the normal Gemini app?

We found nothing documented about this in the public Google documentation. That is why this page only describes the three documented ways.

Does the SmartChat server work on all the ways?

We cannot promise that across the board. For remote servers Google requires Streamable HTTP over HTTPS and does not accept SSE in the Gemini API and Enterprise. Check the details on MCP access in the SmartChat documentation before you set it up.

How does sign-in work?

SmartChat uses OAuth with a consent page where you choose the permissions. According to Google, the Gemini CLI detects the OAuth endpoints by itself. In Gemini Enterprise, an administrator enters the OAuth details in the Custom MCP Server.

Can I restrict tools?

Yes. In the Gemini API, the allowed_tools list limits the tools. In Gemini Enterprise, imported actions are off at first. On top of that, you set the permissions in SmartChat.

Does Gemini ask before making changes?

In Gemini Enterprise, according to Google, every call of an action requires confirmation by default. In the Gemini CLI this applies as long as trust is not switched on.

What stays blocked for Gemini?

Deleting and plan actions such as upgrade, downgrade or cancellation. Everything else the app can do depends on the permissions you choose.

Are there limits?

SmartChat sets no limits of its own for MCP and API. For Gemini Enterprise, Google names a maximum of 100 active actions per data store.

What about the Gemini CLI?

The Google page on it points out that, since June 18, 2026, the Antigravity CLI takes its place for free accounts and Google One. Read up there which way fits your account.

How many automations come with my plan?

Free and Starter include the fixed automation for new contacts. Basic offers 3, one of them fixed, and Pro has no upper limit.

What does SmartChat cost for this?

Free costs €0, Starter €299, Basic €499 and Pro €999 per month, each plus VAT. Sending and automation runs use no credits. You can find Meta's fees here.

Why does an automation only work with an approved template?

For messages outside the inbox, WhatsApp requires a template that Meta has reviewed. SmartChat AI writes it for you and submits it.

How do contacts unsubscribe?

With STOP. After that they are unsubscribed right away and receive neither newsletters nor automations.

Gemini knows the goal. In 60 seconds your system is ready.

Type in your website, and SmartChat AI creates the landing page, confirmation message and thank-you message. Then you connect the MCP server in Gemini.
