The Supabase MCP Server — Full Backend Management Through Your AI Assistant
The Supabase MCP server isn't just a database tool — it's a full backend management interface. While most database MCP servers give you SQL execution and schema inspection, Supabase gives you 8 tool groups covering your entire stack: database, edge functions, storage, branching, debugging, development, knowledge base, and account management.
At a glance: 2.5K GitHub stars, 316 forks, v0.7.0, OAuth 2.1 remote server at mcp.supabase.com
What It Does
| Tool Group | Key Capabilities |
| Database | List tables, extensions, migrations; apply migrations; execute SQL |
| Branching | Create, merge, rebase, reset branches (paid plans) |
| Edge Functions | List, retrieve, deploy functions from your AI assistant |
| Development | Generate TypeScript types, get project URLs and API keys |
| Debugging | Logs from API gateway, PostgreSQL, edge functions, auth, storage |
| Knowledge Base | Search Supabase documentation directly |
| Storage | Manage buckets and configuration (disabled by default) |
| Account | List/create projects and organizations |
Setup — Dead Simple
Remote (recommended):
{
"mcpServers": {
"supabase": {
"url": "https://mcp.supabase.com/mcp"
}
}
}
First connection opens OAuth 2.1 consent. No tokens, no API keys. Add ?read_only=true&project_ref=YOUR_REF for scoped access.
What's Good
Broadest scope of any database MCP server. Deploy edge functions, check logs, manage storage, generate types, and query data — all from one server. No other database-adjacent MCP server comes close.
Read-only mode done right. Queries execute as a dedicated supabase_read_only_user — a real PostgreSQL role, not just query filtering. Better than Neon (which has no read-only mode).
Project scoping + feature group filtering. Restrict to a single project, disable tool groups you don't need. Give your AI staging access without risking production.
Where It Falls Short
Branching is schema-only. Neon's copy-on-write branching duplicates both schema and data instantly. Supabase copies schema only — you need seed scripts. For testing against realistic data, Neon wins.
Branching requires paid plan. The best safety feature for database development is locked behind a paywall. Neon offers branching on its free tier.
OAuth scopes are all-or-nothing. Even if you only enable database tools, the OAuth flow requests full account access (issue #239). Feature group filtering restricts what the LLM sees, but the token has broader permissions.
Pre-1.0 status. Five releases in 2026 show progress toward stability, but breaking changes remain possible.
How It Compares
| Feature | Supabase | Neon |
| Scope | Full BaaS (8 groups) | Database only |
| Read-only | Yes (real PG role) | No |
| Branching | Schema-only (paid) | Copy-on-write (free) |
| Edge functions | Yes | No |
| Storage | Yes | No |
Choose Supabase if you're building on Supabase and want one server for your entire backend. Choose Neon if you need deep database management with instant data branching.
Rating: 4/5
Unmatched breadth — no other database MCP server covers edge functions, storage, debugging, and database management in one package. The security model (real read-only mode, project scoping, feature group filtering) sets a standard. Loses a point for schema-only branching, paid-only branching, and BaaS lock-in. But if you're building on Supabase, this is the obvious choice.
