At a glance: Database MCP servers are the most mature category in the MCP ecosystem. Postgres MCP Pro (2,300 stars) has industrial-strength index tuning. MongoDB's official server ships 40+ tools. Multi-database servers connect to MySQL, PostgreSQL, SQLite, and Oracle simultaneously. Rating: 4/5.
PostgreSQL
| Detail | Info |
|---|---|
| crystaldba/postgres-mcp | ~2,300 stars, MIT, Python |
| Tools | 8 (schema, SQL, query explain, workload analysis, index tuning, health checks) |
Postgres MCP Pro — the clear winner for self-hosted PostgreSQL. Intelligent index tuning employing industrial-strength algorithms. analyze_db_health evaluates index health, connection utilization, buffer cache, vacuum status, and replication lag in a single call. Supports read-only production-safe mode.
Warning: The archived official PostgreSQL MCP server (231 stars) has a SQL injection vulnerability. Do not use it.
MySQL
- benborla/mcp-server-mysql (1,300 stars, MIT) — SSH tunnel support, multi-database config, query caching, connection pooling, rate limiting. The most popular MySQL MCP server.
- designcomputer/mysql_mcp_server (1,200 stars, MIT, Python) — Simpler: 4 core capabilities, environment-variable credentials.
MongoDB — Official Server (959 stars)
| Detail | Info |
|---|---|
| mongodb-js/mongodb-mcp-server | ~959 stars, TypeScript |
| Tools | 40+ (23 database + 12 Atlas + 2 assistant) |
The most feature-rich database MCP server across any platform. Queries, aggregations, vector search indexes, Atlas cluster management, Performance Advisor integration, automatic embedding generation. Granular safety controls including read-only mode.
Redis — Official (452 stars)
redis/mcp-redis (MIT) — Covers all Redis data structures: strings, hashes, lists, sets, sorted sets, streams, JSON, pub/sub. Vector search, EntraID auth, cluster mode, Redis ACL integration.
DynamoDB — AWS Official
Part of awslabs/mcp (Apache-2.0). 8 tools focused on data modeling lifecycle — requirements gathering, schema design, model validation against DynamoDB Local, cost analysis (RCU/WCU), CDK deployment code generation. A design-and-migrate tool, not a runtime query tool.
Supabase (2,500 stars)
supabase-community/supabase-mcp (Apache-2.0) — 30+ tools across account management, database operations, migrations, debugging, edge functions, storage, and TypeScript type generation. 360 commits with active development.
Multi-Database Servers
- FreePeak/db-mcp-server (353 stars, Go) — MySQL, PostgreSQL, SQLite, Oracle, TimescaleDB simultaneously. Lazy loading, Clean Architecture.
- executeautomation/mcp-database-server (320 stars, TypeScript) — SQLite, SQL Server, PostgreSQL, MySQL. AWS IAM auth for RDS.
Tier Recommendations
Tier 1 — Use with confidence:
- Postgres MCP Pro for self-hosted PostgreSQL
- MongoDB MCP (official) for MongoDB
- Supabase MCP for Supabase/PostgreSQL
Tier 2 — Solid choices:
- benborla/mcp-server-mysql for MySQL
- Redis MCP (official) for Redis
- FreePeak/db-mcp-server for multi-database
- AWS DynamoDB MCP for data modeling
Tier 3 — Avoid:
- Official PostgreSQL server (SQL injection vulnerability)
- Official SQLite server (no safety guardrails)
Bottom Line
Rating: 4/5 — The strongest category in the MCP ecosystem. Multiple production-ready options per platform, good safety controls, genuine performance tooling beyond basic CRUD. The community and vendors have built something better than what Anthropic started with.
