Best MCP Servers for Database Operations (2026)
Database MCP servers let AI models query, analyze, and manage databases through natural language. This guide covers the best MCP servers for PostgreSQL, SQLite, and Supabase — with install commands, use cases, and trust scores from XLUXX.
Why Use MCP for Database Access?
Instead of writing SQL manually or building custom integrations, database MCP servers let any MCP-compatible AI client run queries, inspect schemas, and analyze data. The AI generates SQL, the MCP server executes it safely, and results come back structured.
1. PostgreSQL MCP Server
The official PostgreSQL MCP server provides read-only access to Postgres databases.
npm install -g @modelcontextprotocol/server-postgresConfiguration:
{
"mcpServers": {
"postgres": {
"command": "npx",
"args": ["-y", "@modelcontextprotocol/server-postgres"],
"env": {
"POSTGRES_CONNECTION_STRING": "postgresql://user:pass@localhost:5432/mydb"
}
}
}
}Capabilities: Schema inspection, SELECT queries, table listing, row counting.
Use cases: Data analysis, report generation, schema documentation.

2. SQLite MCP Server
Ideal for local databases, prototyping, and embedded data.
pip install mcp-server-sqliteConfiguration:
{
"mcpServers": {
"sqlite": {
"command": "python",
"args": ["-m", "mcp_server_sqlite", "--db-path", "/path/to/database.db"]
}
}
}Capabilities: Full read/write SQL, table creation, schema inspection, data export.
Use cases: Local data analysis, application prototyping, personal databases.

3. Supabase MCP Server
Connects to Supabase projects for managed PostgreSQL with auth and real-time features.
npm install -g supabase-mcp-serverConfiguration:
{
"mcpServers": {
"supabase": {
"command": "npx",
"args": ["-y", "supabase-mcp-server"],
"env": {
"SUPABASE_URL": "https://your-project.supabase.co",
"SUPABASE_SERVICE_KEY": "your-service-key"
}
}
}
}Capabilities: SQL queries, table management, auth user management, storage operations.
Use cases: Full-stack app management, user data analysis, content management.

Comparing Database MCP Servers
| Server | Database | Read/Write | Best For |
|---|---|---|---|
| server-postgres | PostgreSQL | Read-only | Production analytics |
| mcp-server-sqlite | SQLite | Read/Write | Local development |
| supabase-mcp | Supabase (Postgres) | Read/Write | Full-stack apps |
Finding More Database Tools
Use XLUXX to discover additional database MCP servers:
pip install xluxxcurl https://api.xluxx.net/v1/tools?category=database&sort=trust_scoreSecurity Best Practices
- Use read-only database credentials when possible
- Never expose production credentials in config files — use environment variables
- Restrict database user permissions to specific schemas and tables
- Always check XLUXX trust scores before installing third-party MCP servers
Use XLUXX Trust Layer to find reliable MCP tools: api.xluxx.net
