It is guarded to be a no-op where objects already exist. - App env lives in `apps/cursor/.env` (gitignored). For local dev it uses the Supabase CLI's well-known local default keys (`supabase status` prints them) with `NEXT_PUBLIC_SUPABASE_URL=http://127.0.0.1:54321`. `CRON_SECRET` guards `/api/queue/plugin-scans/drain` and `/api/cron/*`. -- The login page only offers GitHub/Google OAuth, which are not configured locally.

Create a confirmed user via the GoTrue admin API (`POST {SUPABASE_URL}/auth/v1/admin/users` with the secret key, `"email_confirm": true`); a DB trigger provisions the `public.users` profile row. To get a browser session, add a temporary route that calls `supabase.auth.signInWithPassword(...)` with the server client (do not commit it). To use `/admin/plugins` and the MCP server, add the user to the `public.admins` table: `insert into public.admins (user_id) values ('')`. Email rows only match Google/GitHub identities, so local password users need a `user_id` row. - Cache Components (`cacheComponents: true`) makes pages with `generateStaticParams` throw 500 on an empty database — seed at least one active plugin. Use `bun run seed:extract` / `seed:insert`, but note: the insert script must be run as `bun run --conditions=react-server --env-file=apps/cursor/.env apps/cursor/src/scripts/insert-from-jsonl.ts` or the `server-only` import throws under plain `bun run`. GitHub Code Search (used by `seed:extract` discovery) is heavily rate-limited; hand-writing `apps/cursor/.seed/candidates.json` with `{"candidates":[{"owner":...,"repo":...,"source":"seed:topic","matchedQuery":"manual"}]}` skips discovery. - Seeded plugin logos hosted on `raw.githubusercontent.com` 500 plugin pages because that host is not in `next.config.mjs` `images.remotePatterns`; null them: `update plugins set logo = null where logo like 'https://raw.githubusercontent.com%'`. - After changing `.env` or database content backing cached pages, restart `bun dev` (and `rm -rf apps/cursor/.next` if stale renders persist) — hot reload does not invalidate Cache Components output. - Without `CURSOR_API_KEY`, plugin submission works but the security scan errors (plugin lands in the admin "Scan issues" queue, where an admin can publish it manually). This is expected locally. - Supabase `edge_runtime` is disabled in `supabase/config.toml` (no edge functions in this app; its boot probe needs deno.land which is blocked). +- Community Plugins MCP server (`/api/mcp`): the local Supabase OAuth 2.1 server is enabled in `config.toml`.

Locally the authorization server metadata is served at `http://127.0.0.1:54321/auth/v1/.well-known/oauth-authorization-server` (the RFC 8414 path-inserted URL 404s), which MCP SDK clients find via their OIDC fallback. Drive the flow with the official MCP client SDK (`@modelcontextprotocol/sdk`): a 401 from `/api/mcp` starts discovery, the browser step lands on `/oauth/consent`. GoTrue auto-approves clients a user already consented to on the first authorization-details fetch (the code is issued immediately and the authorization is consumed); `delete from auth.oauth_consents` resets that locally. +- If `supabase start` fails with Realtime "connection not available" while initialising the schema, containers cannot reach each other because a legacy iptables `FORWARD DROP` policy is present: `sudo iptables-legacy -P FORWARD ACCEPT`, then retry.
