Which Database MCP Server Should You Use? I Compared the Top 6
Your AI assistant can now query your database directly. No more copy-pasting SQL results into chat. But there are 183 database MCP servers — which one actually works for YOUR stack?
I tested the top 6 across Postgres, MySQL, SQLite, MongoDB, Redis, and Supabase.
Quick Decision Table
| Your Database | Use This | Why |
| PostgreSQL | `@modelcontextprotocol/server-postgres` | Official MCP team. Read-only by default. Stable. |
| MySQL | `@benborla29/mcp-server-mysql` | Best MySQL support with schema introspection |
| SQLite | `@modelcontextprotocol/server-sqlite` | Official. Great for local dev + prototyping |
| MongoDB | `mcp-mongo-server` | Full CRUD with aggregation pipeline support |
| Redis | `@modelcontextprotocol/server-redis` | Official. Key-value ops + pub/sub |
| Supabase | `@supabase/mcp-server` | Supabase-specific: auth, storage, edge functions, not just SQL |
PostgreSQL — The Safe Default
If you're on Postgres (and most of you are), use the official one:
claude mcp add postgres npx -y @modelcontextprotocol/server-postgres postgresql://user:pass@localhost/mydb
It connects read-only by default. Your AI can explore schemas, run SELECT queries, and analyze data without risking writes. Perfect for "what does my user_sessions table look like?" or "find all orders over $100 from last week."
When to pick something else: If you need write access or Postgres-specific features (pgvector, PostGIS), look at the specialized servers on Protodex's database category.
Supabase — More Than a Database
If you're on Supabase, don't use the generic Postgres server. The Supabase MCP server understands your whole stack:
claude mcp add supabase npx -y @supabase/mcp-server
It can manage auth users, storage buckets, edge functions, and RLS policies — not just SQL. "Create a new table with RLS for authenticated users" works as one prompt.
SQLite — For Prototyping
Building something locally? SQLite MCP is the fastest way to give your AI a database:
claude mcp add sqlite npx -y @modelcontextprotocol/server-sqlite /path/to/your.db
Point it at any .db file. Instant data exploration. I use this for analyzing datasets — drop a CSV into SQLite, connect MCP, ask questions.
MongoDB — When Your Data Isn't Relational
claude mcp add mongo npx -y mcp-mongo-server mongodb://localhost:27017/mydb
Full aggregation pipeline support. "Show me the average order value grouped by country for the last 30 days" translates directly to a Mongo aggregation.
Security Warning
Every database MCP server has your connection string. Before installing any:
1. Use read-only credentials when possible
2. Never use production credentials in Claude Desktop (config file is plain text)
3. Check the security score on Protodex before installing
4. Prefer official servers (marked ✓ Secure on Protodex) over community ones
