<!-- ccr-slack-attribution --> _Requested by **Saxon Fletcher** · [Slack thread](https://supabase.slack.com/archives/C051L8U2EJF/p1789995309253479?thread_ts=1789995309.253479&cid=C051L8U2EJF)_ Resolves AI-1246 ## Problem **Before:** The Assistant's `list_policies` tool fails in about 70% of traces. It only "succeeds" when the org has AI opt-in disabled, because then it returns the privacy stub and never makes a request. When opt-in is enabled, it runs the pg-meta query server-side with no `Authorization` header, so the request is unauthenticated and fails. The Assistant then falls back to `execute_sql`. **After:** `list_policies` sends the caller's `Authorization` header, the same way `execute_sql` in `studio-tools.ts` already does, so it returns the project's RLS policies. ## Solution `getTools` already receives `authorization` but didn't pass it to `getSchemaTools`. This PR passes it through. `list_policies` builds `{ Authorization }` from it, and `getDatabasePolicies` gets an optional `headersInit` argument that it forwards to `executeSql`, the same pattern `getDatabaseFunctions` uses. Existing client-side callers of `getDatabasePolicies` don't change. Files: `lib/ai/tools/index.ts`, `lib/ai/tools/schema-tools.ts`, `data/database-policies/database-policies-query.ts`, plus tests in `lib/ai/tools/schema-tools.test.ts` (new) and `lib/ai/tools/index.test.ts`. ## Review instructions 1. Read `schema-tools.ts` and compare it with the `authHeaders` handling in `studio-tools.ts` (`execute_sql`). 2. On the preview, use an org with AI opt-in set to at least "schema" and ask the Assistant to list the RLS policies on `public`. `list_policies` should return the policies without falling back to `execute_sql`. Local gates (all passed): - `pnpm typecheck` in `apps/studio` (next typegen + `tsc --noEmit`) - `npx eslint` on touched files: 0 errors. The 2 warnings are on lines this PR doesn't change. - `npx vitest run lib/ai/tools/schema-tools.test.ts lib/ai/tools/index.test.ts lib/ai/tool-filter.test.ts`: 24/24 passed. I also ran the new header test against the old `schema-tools.ts` and it failed, as expected. - `SORT_IMPORTS=false npx prettier --config prettier.config.mjs --check` on touched files Follow-up, not in this PR: `getRlsKnowledge` in `fallback-tools.ts` (self-hosted path) also calls `getDatabasePolicies` without headers, even though a `headers` object is already in scope there. ## AI disclosure Claude Code (agent) wrote this PR from the Slack request. @SaxonF (Saxon Fletcher) is the accountable human owner.

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
masterand 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.
- Type:
- 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 pullfrequently 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
infrastructurerepo.
# 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=
