Best MCP Servers for Database & SQL
Top-ranked MCP servers for database access — PostgreSQL, MySQL, SQLite, MongoDB, Redis, and more. Scored by stars, freshness, issue health, and real usage signals.
Database MCP servers give AI agents direct, structured access to SQL and NoSQL databases through the Model Context Protocol. Instead of writing raw connection code, you define the query in natural language and the MCP server handles translation, execution, and type-safe results.
This guide ranks the top-performing database MCP servers from the AgentRank index — covering PostgreSQL, MySQL, SQLite, MongoDB, Redis, DuckDB, and cloud databases like Neon, Supabase, and PlanetScale. Scores are computed from a five-signal composite: stars, freshness, issue health, contributor depth, and inbound dependents.
Top Database & SQL MCP servers
Ranked by the composite AgentRank score — a weighted blend of stars (10%), freshness (20%), issue health (20%), contributors (8%), and inbound dependents (22%). Average score across these 8 tools: 90.5.

Choosing by use case
- Relational DBs (Postgres, MySQL)
- Query and manage structured data with full SQL support, schema inspection, and transactional writes.
- Document stores (MongoDB)
- Flexible schema access for document-based data with aggregation pipeline support.
- Caching & real-time (Redis)
- Key-value reads/writes, pub-sub, and sorted sets for session data, leaderboards, and real-time feeds.
- Analytics & OLAP (DuckDB)
- In-process columnar queries over Parquet, CSV, and large local datasets at analytical speed.
Quick setup
Most MCP servers follow the same config pattern. Add this to your Claude Desktop, Cursor, or Windsurf MCP config file:
{
"mcpServers": {
"postgres": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-postgres", "postgresql://localhost/mydb"]
}
}
}See the integrations page for platform-specific setup guides for Claude Code, Cursor, VS Code, Windsurf, and Cline.
Reading the AgentRank signals
Each tool in this guide is scored on the core signals that predict long-term reliability:
| Signal | Weight | What it means |
|---|---|---|
| Stars | 15% | Raw popularity — how many developers have found and bookmarked this tool |
| Freshness | 25% | Days since last commit — tools with no recent commits decay hard after 90 days |
| Issue health | 25% | Ratio of closed to total issues — measures maintainer responsiveness |
| Contributors | 10% | More contributors = less bus-factor risk, broader review surface |
| Dependents | 25% | How many other repos depend on this — the strongest signal of real-world adoption |
