How to Connect Bubble to Claude (and What It Can't Do)
You built your product on Bubble, and now you’d like Claude to see inside it — count this week’s signups, inspect a Booking record, sanity-check how your data types relate. That’s possible today, but only through the community route. As of mid-2026, Bubble has no listing in Anthropic’s connector directory and publishes no MCP server of its own. What exists instead are community-built servers, like the open-source bubble_mcp, that sit between Claude and your app’s Data API.
That distinction matters for both setup effort and trust, so it’s worth understanding what these servers do before handing one your API token.
What a community Bubble MCP server gives Claude
The better community servers speak Bubble’s actual vocabulary. bubble_mcp, for instance, auto-discovers your data types from the Data API, supports create/read/update/delete on things, can kick off API workflows you’ve exposed, respects your privacy rules, and offers a read-only mode if you’d rather Claude never write anything.
Wired up, a Bubble founder’s chats start looking like this:
- “List the fields on my Booking data type and tell me which ones are empty on most records.”
- “How many Users signed up in the last seven days, and how many of them chose the Pro plan?”
- “Set the status field on Order 1089 to ‘refunded’ and confirm the change.” (read-write mode only)
That last category — plain-language database surgery without opening the App Data tab — is the honest appeal here.
Setup runs through the Data API
- In the Bubble editor, open Settings → API: enable the Data API, tick each data type you want exposed, and generate an API token.
- Run a community MCP server with your app’s URL and that token — most, including bubble_mcp, take these as environment variables along with a read-only/read-write mode flag.
- In Claude, add it under Settings → Connectors as a custom connector. Custom connectors are effectively a paid-Claude-plan feature — the free tier caps you at a single one.
- Test against your development version (
version-test) before pointing anything at live data.
Two cautions specific to Bubble. Your API token typically acts with admin-level rights, so privacy rules you wrote for logged-in users won’t protect data from the token — expose data types deliberately, not wholesale. And a community server is unvetted code holding that token; read it or self-host it before trusting it, since it sits outside Anthropic’s directory.
Your backend workflows react to the database — Claude doesn’t
Bubble’s whole appeal is that the app runs itself: a database trigger event fires a backend workflow the instant a record changes, and recurring workflows run on schedules. Claude lives outside all of that. When a User is created at midnight, your Bubble backend workflows fire — but no Claude conversation exists, so nothing you’ve connected to Claude happens. The connector answers questions during a chat you opened; it cannot subscribe to your database.
So the realistic division of labor: Claude is excellent for ad-hoc inspection, data cleanup, and “explain my own schema back to me” sessions. It is structurally incapable of “when X happens in my app, do Y” — no matter which MCP server you pick.
Acting on app events without opening a chat: Carly
The moment the job is event-shaped — a new signup should get a personal welcome email, a failed payment should open a follow-up task, a submitted application should be summarized and routed — you want an agent with triggers, not a chat with a connector.
Carly is an AI executive assistant built around exactly that. It watches for events around your app and acts 24/7 in the cloud: sending real email through Gmail or Outlook (with attachments), creating and updating tasks, keeping records in sync across the 200+ tools it connects to (see integrations). And rather than configuring anything yourself, you tell Carly the outcome in plain English — “email every new signup a welcome note that mentions the plan they picked” — and it interviews you about the details, then builds the workflow with you. AI agents start at $35/month, and steps that don’t use AI run free and unlimited.

Frequently Asked Questions
Does Claude integrate with Bubble?
Only through community-built MCP servers as of mid-2026 — there’s no Bubble entry in Anthropic’s connector directory and no official server from Bubble. A community server connected to your app’s Data API lets Claude query and (optionally) edit your data inside a chat, added as a custom connector on a paid Claude plan.
Can Claude respond to events in my Bubble app?
No. Database trigger events and scheduled workflows run inside Bubble; Claude’s connectors only function in a conversation you start, so nothing in your app can invoke Claude. Event-driven follow-up is agent-platform territory — that’s what Carly does.
Is it safe to give an MCP server my Bubble API token?
Treat it like admin access, because it usually is — privacy rules don’t constrain the token the way they constrain users. Expose only the data types you need, prefer read-only mode for exploration, and only run community server code you’ve reviewed or self-hosted.
Can Claude build pages or workflows in my Bubble editor?
No. These servers talk to the Data API — records and API workflows — not the editor. Your pages, design, and workflow logic still get built by hand in Bubble.
How do I get new signups handled automatically?
Connect the job to Carly instead of a chat: it fires on events around your app 24/7 in the cloud, drafts and sends the emails, and opens the tasks. AI agents start at $35/month.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
