   npm run build
   

4. Configure the MCP settings file:

   {
     "mcpServers": {
       "postgresql-mcp": {
         "command": "node",
         "args": ["/path/to/postgresql-mcp-server/build/index.js"],
         "disabled": false,
         "alwaysAllow": [],
         "env": {
           "POSTGRES_CONNECTION_STRING": "postgresql://username:password@server:port/dbname"
         }
       }
     }

📚 Documentation

Development Guide

• Start in Development Mode: Use npm run dev to start a development server with hot-reloading.
• Code Check: Run npm run lint to perform ESLint checks.
• Unit Testing: Execute npm test to run all test cases.

Security Considerations

Connection Security

• Adopt a connection pool mechanism.
• Implement connection timeout control.
• Validate the validity of the connection string.
• Support SSL/TLS encrypted connections.

Query Security

• Validate the legitimacy of SQL queries.
• Prevent the execution of dangerous operations.
• Set query timeout limits.
• Record all operation logs.

Authentication

• Support multiple authentication methods.
• Implement role-based access control.
• Enforce password policies.
• Securely manage connection credentials.

Best Practices

1. Always use a secure connection string and ensure it contains the correct credentials.
2. Follow the security recommendations for the production environment in sensitive environments.
3. Regularly monitor and analyze database performance.
4. Keep the PostgreSQL version up-to-date.
5. Implement an appropriate data backup strategy.
6. Use a connection pool to optimize resource management.
7. Implement comprehensive error handling and logging.
8. Conduct regular security audits and updates.

Error Handling

The server implements a comprehensive error handling mechanism:

• Common Errors: Such as connection timeouts, query failures, etc.
• Custom Errors: Provide detailed feedback for specific issues.
• Error Logs: Facilitate users to view and analyze.

Configuration Example

# Example configuration command
POSTGRES_CONNECTION_STRING="postgresql://admin:password@localhost:5432/mydb"

Diagnostic Tools

Command-line Tools

# Check database status
