Allows execution of SQL queries on PostgreSQL databases with configurable read-only or write access permissions, returning structured results with metadata
Simple PostgreSQL MCP Server
A minimal Model Context Protocol (MCP) server for executing SQL queries on PostgreSQL databases with configurable permissions.
Features
Execute SQL queries with optional read-only or write access
Server-level mode (read-only/write) configurable via command line
Returns structured results with metadata
Simple setup using a PostgreSQL connection string
Getting Started
Clone the repository
git clone https://github.com/perrypixel/Simple-Postgres-MCP cd Simple-Postgres-MCPInstall dependencies
npm installBuild the project
npm run build
MCP Configuration
Add the following to your MCP client configuration (mcp.json):
Write Mode (default)
{
"mcpServers": {
"simple-postgresql-mcp": {
"command": "node",
"args": [
"/path/to/build/index.js",
"postgresql://username:password@localhost:5432/database_name",
"write"
]
}
}
}
Read-Only Mode
{
"mcpServers": {
"simple-postgresql-mcp": {
"command": "node",
"args": [
"/path/to/build/index.js",
"postgresql://username:password@localhost:5432/database_name",
"readonly"
]
}
}
}
Note: Update the path in the configuration to point to the
index.jsfile inside yourbuildfolder.
Usage
Copy the appropriate MCP configuration (read-only or write mode) to your tool’s
mcp.json(e.g., Cursor, Windsurf, Copilot, etc.).Start your MCP client. The server is now ready to use!
