- Eval harness's only live tool, `search_docs`, no longer needs the in-process MCP client or its dummy token — it now calls the public docs GraphQL API (`https://supabase.com/docs/api/graphql`) directly. Low risk as this is an eval-harness change only. Production assistant path (`mcp-tools.ts`) untouched. **Update:** per [@mattrossman's review](https://github.com/supabase/supabase/pull/50092#discussion_r3980396341), the eval tool's description embeds the Content API's own GraphQL schema (fetched via a `{ schema }` query and minified with `gqlmin`), mirroring how `@supabase/mcp-server-supabase`'s `docs-tools.ts`/`loadSchema` populates production's `search_docs` description. Without it, the model had no schema to work from and issued malformed queries, which caused the 218 `search_docs` errors and the -25pp Docs Faithfulness regression in the first eval run on this PR. Schema loading is required: `createSearchDocsTool()` rejects if the schema fetch fails, so preflight and the gated eval job fail loudly instead of producing untrustworthy fallback results. `createSearchDocsTool` is async because the `ai` package's `tool()` only accepts a plain string `description`, unlike the MCP SDK's async description support; both callers (`getMockTools`, `evals/preflight.ts`) await it. `gqlmin` is a direct `apps/studio` dependency and was already transitive via `@supabase/mcp-server-supabase`. ### Verification - `pnpm -C apps/studio exec -- tsc --noEmit` reaches the compiler; it reports only the pre-existing unrelated `packages/ui-patterns/src/McpUrlBuilder/components/InstructionBlocks.tsx` `StaticImageData` error. - `pnpm -C apps/studio exec -- vitest run lib/ai/tools/mock-tools.test.ts lib/ai/tools/mcp-tools.test.ts` — 21/21 passed. - `pnpm exec tsx evals/preflight.ts` — live docs API schema fetch and search_docs call passed. - `NEXT_PUBLIC_CONTENT_API_URL=http://127.0.0.1:1/graphql pnpm -C apps/studio exec -- tsx evals/preflight.ts` — failed fast as expected, proving schema/API failures gate evals. - Fresh `run-evals` pass: Docs Faithfulness 55.7% (0pp), with no systemic `search_docs` regression. Risk: eval-harness-only; schema/API outage now fails the eval job before scoring rather than allowing fallback descriptions. <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added documentation search powered by the public Supabase documentation GraphQL API. * Documentation search results now include live schema information and clearer error handling for failed or invalid requests. * **Bug Fixes** * Improved evaluation tooling reliability by removing unnecessary connection-abort behavior. * Updated validation to detect missing search tools and malformed documentation responses. <!-- end of auto-generated comment: release notes by coderabbit.ai --> --------- Co-authored-by: Claude Sonnet 5 <noreply@anthropic.com>

How it works
Supabase is a combination of open source tools. We’re building the features of Firebase using enterprise-grade, open source products. If the tools and communities exist, with an MIT, Apache 2, or equivalent open license, we will use and support that tool. If the tool doesn't exist, we build and open source it ourselves. Supabase is not a 1-to-1 mapping of Firebase. Our aim is to give developers a Firebase-like developer experience using open source tools.
Architecture
Supabase is a hosted platform. You can sign up and start using Supabase without installing anything. You can also self-host and develop locally.
- Postgres is an object-relational database system with over 30 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.
- Realtime is an Elixir server that allows you to listen to PostgreSQL inserts, updates, and deletes using websockets. Realtime polls Postgres' built-in replication functionality for database changes, converts changes to JSON, then broadcasts the JSON over websockets to authorized clients.
- PostgREST is a web server that turns your PostgreSQL database directly into a RESTful API.
- GoTrue is a JWT-based authentication API that simplifies user sign-ups, logins, and session management in your applications.
- Storage a RESTful API for managing files in S3, with Postgres handling permissions.
- pg_graphql a PostgreSQL extension that exposes a GraphQL API.
- postgres-meta is a RESTful API for managing your Postgres, allowing you to fetch tables, add roles, and run queries, etc.
- Envoy is a cloud-native, high-performance edge and service proxy.
Client libraries
Our approach for client libraries is modular. Each sub-library is a standalone implementation for a single external system. This is one of the ways we support existing tools.
