+**Constructive GraphQL Server** is an Express-based server built on PostGraphile. It reads Constructive metadata to select API schemas, applies RLS-aware auth, and exposes a production-ready GraphQL API.
+
+## 🚀 Quick Start
+
+### Use as SDK
+
+Install the package:
+
+```bash
+pnpm add @constructive-io/graphql-server @constructive-io/graphql-env
+```
+
+Start a server:
+
+```ts
+import { getEnvOptions } from '@constructive-io/graphql-env';
+import { GraphQLServer } from '@constructive-io/graphql-server';
+
+GraphQLServer(
+  getEnvOptions({
+    pg: { database: 'constructive_db' },
+    server: { host: '0.0.0.0', port: 3000 }
+  })
+);
+```
+
+> **Tip:** Set `PGHOST`, `PGPORT`, `PGUSER`, `PGPASSWORD`, `PGDATABASE` to control DB connectivity.
+See [Configuration](#configuration) for the full list of supported env vars and defaults.
+
+### Local Development (this repo)
+
+```bash
+pnpm install
+cd graphql/server
+pnpm dev
+```
+
+This starts the server with env defaults from `@constructive-io/graphql-env`.
+> **Tip:** Set `PGHOST`, `PGPORT`, `PGUSER`, `PGPASSWORD`, `PGDATABASE` to control DB connectivity.
+See [Configuration](#configuration) for the full list of supported env vars and defaults.
+
+
+## What it does
+
+Runs an Express server that wires CORS, uploads, domain parsing, auth, and PostGraphile into a single GraphQL endpoint. It serves `/graphql` and `/graphiql`, injects per-request `pgSettings`, and flushes cached schemas on demand or via database notifications. When meta API is enabled, it resolves API config (schemas, roles, modules) from the meta schema using the request host and enforces `api.isPublic`, with optional header overrides in private mode; when meta API is disabled, it serves the fixed schemas and roles from `api.exposedSchemas`, `api.anonRole`, `api.roleName`, and `api.defaultDatabaseId`.
+
+## Key Features
+
+- Automatic GraphQL API generation from PostgreSQL schemas
+- RLS-aware authentication and per-request `pgSettings`
+- Meta-schema routing by domain + subdomain
+- File uploads via `graphql-upload`
+- GraphiQL and health check endpoints
+- Schema cache flush via `/flush` or database notifications
+
+## Routes
+
+- `GET /healthz` -> health check
+- `GET /graphiql` -> GraphiQL UI
+- `GET /graphql` / `POST /graphql` -> GraphQL endpoint
+- `POST /graphql` (multipart) -> file uploads
+- `POST /flush` -> clears cached Graphile schema for the current API
+
+## Meta API routing
+
+When `API_ENABLE_META=true` (default):
+
+- The server resolves APIs from `meta_public.domains` using the request host.
+- Only APIs where `api.is_public` matches `API_IS_PUBLIC` are served.
+- In private mode (`API_IS_PUBLIC=false`), you can override with headers:
+  - `X-Api-Name` + `X-Database-Id`
+  - `X-Schemata` + `X-Database-Id`
+  - `X-Meta-Schema` + `X-Database-Id`
+
+When `API_ENABLE_META=false`:
+
+- The server skips meta lookups and serves the fixed schemas in `API_EXPOSED_SCHEMAS`.
+- Roles and database IDs come from `API_ANON_ROLE`, `API_ROLE_NAME`, and `API_DEFAULT_DATABASE_ID`.
+
+## Configuration
+
+Configuration is merged from defaults, config files, and env vars via `@constructive-io/graphql-env`. See `graphql/env/README.md` for the full list and examples.
+
+| Env var | Purpose | Default |
+| --- | --- | --- |
+| `PGHOST` | Postgres host | `localhost` |
+| `PGPORT` | Postgres port | `5432` |
+| `PGUSER` | Postgres user | `postgres` |
+| `PGPASSWORD` | Postgres password | `password` |
+| `PGDATABASE` | Postgres database | `postgres` |
+| `GRAPHILE_SCHEMA` | Comma-separated schemas to expose | empty |
+| `FEATURES_SIMPLE_INFLECTION` | Enable simple inflection | `true` |
+| `FEATURES_OPPOSITE_BASE_NAMES` | Enable opposite base names | `true` |
+| `FEATURES_POSTGIS` | Enable PostGIS support | `true` |
+| `API_ENABLE_META` | Enable meta API routing | `true` |
+| `API_IS_PUBLIC` | Serve public APIs only | `true` |
+| `API_EXPOSED_SCHEMAS` | Schemas when meta routing is disabled | empty |
+| `API_META_SCHEMAS` | Meta schemas to query | `collections_public,meta_public` |
+| `API_ANON_ROLE` | Anonymous role name | `administrator` |
+| `API_ROLE_NAME` | Authenticated role name | `administrator` |
+| `API_DEFAULT_DATABASE_ID` | Default database ID | `hard-coded` |
+
+## Testing
+
+Use `supertest` or your HTTP client of choice against `/graphql`. For RLS-aware tests, provide a `Bearer` token and ensure the API's auth function is available.
