Charis ee59d28240 fix(studio): reject unknown database_identifier before writing a notebook (#49333)
## Summary
- `create_notebook`/`update_notebook` now validate every
`database_cell`'s `database_identifier` against the project's real
database list (`getReadReplicas`) before writing, throwing an
assistant-actionable `NotebookToolError` (same pattern as the existing
`expected_updated_at` mismatch check) when it doesn't match.
- Only fetches the database list when a cell actually sets
`database_identifier` — no added cost for the common case.
- `update_notebook` validates only the cells its own operations
introduce (`insert_cell`/`replace_cell`), not the whole resulting
notebook — otherwise an unrelated, untouched pre-existing cell whose
replica was removed after the fact would block updates that never touch
it.

Part 4/6 of the stack for FE-4225 (expose valid database identifiers to
the notebook AI agent). Stacked on #49332. This closes the gap that PR 3
reopened: a model can no longer invent an identifier that silently
breaks a cell — it now gets a retryable error naming `list_databases`
(added in #49328) as the way to find a real one.

## Test plan
- [x] `create_notebook`/`update_notebook` reject an unknown
`database_identifier` with `NotebookToolError` + `exposeToAssistant:
true`
- [x] Both succeed when the identifier matches a real database
- [x] `create_notebook` never calls the databases endpoint when no cell
sets `database_identifier`
- [x] `update_notebook` succeeds without validating or fetching
databases when no operation introduces a database_cell, even if an
untouched existing cell carries a now-invalid identifier
- [x] `pnpm --filter studio exec tsc --noEmit` passes

## Summary by CodeRabbit

* **New Features**
* Added a database-listing tool that provides database identifiers and
metadata, including primary-database status.
  * Database results now return only the relevant fields.

* **Bug Fixes**
* Added validation to prevent notebooks from referencing unknown
databases.
* Create and update actions now provide clear errors for invalid
database identifiers.
* Updates validate newly added or replaced cells while preserving
existing, untouched cells.

Supabase Studio

A dashboard for managing your self-hosted Supabase project, and used on our hosted platform. Built with:

What's included

Studio is designed to work with existing deployments - either the local hosted, docker setup, or our CLI. It is not intended for managing the deployment and administration of projects - that's out of scope.

As such, the features exposed on Studio for existing deployments are limited to those which manage your database:

  • Table & SQL editors
    • Saved queries are unavailable
  • Database management
    • Policies, roles, extensions, replication
  • API documentation

Managing Project Settings

Project settings are managed outside of the Dashboard. If you use docker compose, you should manage the settings in your docker-compose file. If you're deploying Supabase to your own cloud, you should store your secrets and env vars in a vault or secrets manager.

How to contribute?

  • Branch from master and name your branches with the following structure
    • {type}/{branch_name}
      • Type: chore | fix | feature
      • The branch name is arbitrary — just make sure it summarizes the work.
  • When you send a PR to master, it will automatically tag members of the frontend team for review.
  • Review the main contributing guide to help test your feature before sending a PR.
  • The Dashboard is under active development. You should run git pull frequently to make sure you're up to date.

Developer Quickstart

Note

Supabase internal use: To develop on Studio locally with the backend services, see the instructions in the internal infrastructure repo.

# You'll need to be on Node v22
# in /studio

## For external contributors
pnpm install # install dependencies
pnpm run dev # start dev server

## For internal contributors
## First clone the private supabase/platform repo and follow instructions for setting up mise
mise studio  # Run from supabase/platform alongside `mise infra`

## For all
pnpm run test # run tests
pnpm run test -- --watch # run tests in watch mode

Running within a self-hosted environment

Follow the self-hosting guide to get started.

cd ..
cd docker
docker compose -f docker-compose.yml -f ./dev/docker-compose.dev.yml up

Once you've got that set up, update .env in the studio folder with the corresponding values.

POSTGRES_PASSWORD=
SUPABASE_ANON_KEY=
SUPABASE_SERVICE_KEY=

Then run the following commands to install dependencies and start the dashboard.

npm install
npm run dev

If you would like to configure different defaults for "Default Organization" and "Default Project", you will need to update the .env in the studio folder with the corresponding values.

DEFAULT_ORGANIZATION_NAME=
DEFAULT_PROJECT_NAME=
