Supabase MCP Server (Official)
MCP server for Supabase — gives agents full access to manage Supabase projects including Postgres databases, tables, RLS policies, Edge Functions, Storage buckets, and project settings via the Supabase Management API.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
RLS is Supabase's core security model — use it. Service Role Key bypasses RLS entirely — critical to restrict agent access. SOC2 Type II, HIPAA BAA available. Postgres connection string contains credentials — treat as highly sensitive. Network restrictions available on Pro plan.
⚡ Reliability
Best When
Your agent needs to manage a Supabase backend — provisioning tables, managing auth, deploying edge functions. The official MCP server provides comprehensive project management capabilities.
Avoid When
You just need to query data — use mcp-server-postgres against Supabase's Postgres connection string instead. The management MCP has broader privileges than needed for read-only data access.
Use Cases
- • Agents creating and managing database schemas on Supabase Postgres
- • Managing Row Level Security policies for access control
- • Deploying and invoking Supabase Edge Functions from agent workflows
- • Uploading and managing files in Supabase Storage
- • Querying database contents and managing auth users
Not For
- • High-frequency real-time data (use Supabase's Realtime channels, not MCP)
- • Direct database connections at scale (use connection pooling via pgBouncer)
- • Production schema migrations without safeguards (agents can drop tables)
Interface
Authentication
Supabase Personal Access Token (PAT) or Service Role Key. PAT for management API (project creation, schema management). Service Role Key for bypassing RLS in data operations. Use anon key for user-scoped data access with RLS.
Pricing
Generous free tier for development. Free tier pauses after 1 week of inactivity. Pro plan includes point-in-time recovery. Compute add-ons for production scale.
Agent Metadata
Known Gotchas
- ⚠ Service Role Key bypasses ALL Row Level Security — agents using this key have unrestricted DB access
- ⚠ Free tier project pausing can catch agents off-guard — must resume before operations work
- ⚠ Schema changes via MCP affect production immediately — no staging/preview built into the MCP server
- ⚠ Supabase Postgres connection string has connection limits — high-concurrency agents need pooler URL
- ⚠ Edge Functions have cold start latency — first invocation after idle period can take 1-2 seconds
- ⚠ MCP server is community-maintained (supabase-community), not official Supabase engineering
