Uses Supabase PAT for management operations. Same security considerations as supabase-mcp-server. Service Role Key bypasses RLS entirely — use with caution in agent contexts.

Best When

An agent needs to interact with a Supabase-hosted PostgreSQL project, especially for schema management, data querying, or managing Supabase-specific features like Auth and Storage.

Avoid When

You are not using Supabase, or you need to manage a non-Supabase PostgreSQL database.

Use Cases

  • Running SQL queries against Supabase PostgreSQL databases from agents
  • Managing database schema changes including table and column operations
  • Interacting with Supabase Auth for user management automation
  • Querying and managing Supabase Storage buckets and files
  • Creating and deploying Supabase Edge Functions via agents

Not For

  • Non-Supabase PostgreSQL databases (use direct pg drivers instead)
  • Extremely high-throughput transactional workloads
  • Teams requiring on-premise deployment
  • Projects needing proprietary database features (use RDS/Cloud SQL)

Authentication

Methods: api_key
OAuth: No Scopes: No

Supabase personal access token (PAT) for MCP server auth. Project-specific anon and service_role keys for client SDK. Service role key grants full database access — handle carefully.

Pricing

Model: freemium
Free tier: Yes
Requires CC: No

Very generous free tier. Pro plan needed for production workloads with higher limits. Paused projects after 1 week inactivity on free tier.

Known Gotchas

  • Free tier projects pause after 1 week of inactivity — first request after pause has cold start
  • Service role key bypasses Row Level Security — agents using it have full unfiltered access
  • MCP server requires npx to run — adds Node.js dependency
  • Database branch management (multiple environments) requires Pro plan
  • Storage file operations return URLs that expire — agents must handle URL refresh
  • Edge functions require Deno runtime knowledge — different from Node.js
