ADoor vs Supabase MCP
Supabase MCP connects AI tools to your Supabase projects, and it works with your developer permissions. Supabase says not to give it to customers or end users, and to use it internally as a developer tool. ADoor is your data account. ChatGPT, Claude, Grok, Cursor and your apps work from the same tables, each with its own access, and every row change can be undone.
Where ADoor stands out
Access per connection
A Supabase MCP connection can be scoped to one project, set to read-only, or limited to feature groups. In ADoor each assistant gets its own access: everything, read and write in one space, or read-only in one space. It can't raise its own access, and you revoke it in one step.
Undo for row changes
Supabase recommends branching to test changes before they reach production, and its MCP asks for confirmation when it detects destructive SQL, which it calls a guardrail, not a guarantee. ADoor records every insert, update and delete with who made it and what it replaced, and you can undo one change without overwriting later edits, including a large write. A field type change keeps the previous values for 30 days. DROP TABLE, TRUNCATE and a dropped field go to Recently deleted for 30 days and can be restored.
Made for the people whose data it is
Supabase MCP is for the developer of a project. ADoor is for the person who owns the data: they connect their own assistants and approve each one.
Side by side
| Topic | ADoor | Supabase MCP |
|---|---|---|
| Who it's for | You, for your own lists and tables, and the people you share them with | Developers building on a Supabase project |
| Sign-in | OAuth from the assistant. ChatGPT, Claude, Grok and Cursor. | OAuth to your Supabase organization, or a personal access token in CI |
| What a connection can do | What you approve: everything, one space read and write, or one space read-only | Your developer permissions, optionally one project, read-only or fewer feature groups |
| More access | The agent asks with request_access, and a person approves | Change the connection's URL options |
| Undo | Undo a row change, a large write, or a field type change, without overwriting later edits | No undo tool. Branching for testing changes, and daily backups and point-in-time recovery on the platform |
| Destructive SQL | Logged; DROP and TRUNCATE stay undoable for 30 days | A confirmation, when the client supports it |
| Other tools | Tables, SQL, sharing and history | Also migrations, Edge Functions, branches, logs and project management |
| Underneath | Standard Postgres | Your project's Postgres |
Which one should you use?
Use Supabase MCP when
you're building an app on Supabase and want your coding agent to read the schema, write migrations, deploy Edge Functions and check logs. Scope it to a development project, as Supabase recommends.
Use ADoor when
the data is yours or your team's, several assistants and apps need it, and you want each one to have its own access you can limit, review and undo.
You can use both: Supabase for your app's backend, ADoor for the lists your assistants keep for you.
Questions people ask
Can I give Supabase MCP to my users?
Supabase advises against it: the server runs with your developer permissions. In ADoor, each person connects their own assistants to their own account.
Does ADoor run on Postgres too?
Yes. ADoor runs on standard Postgres, and SQL works through MCP and the API, within each connection's access.
What does ADoor do about prompt injection?
It can't stop text in a row from steering an agent. It limits the damage: read-only access for agents that read outside text, approvals for more access, undo for bad writes and revoke in one step. See how undo works.
