Configuration (for Cline/Windsurf)

Add this server to your MCP client's settings file (e.g., c:\Users\<User>\AppData\Roaming\Windsurf\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json):

{ "mcpServers": { // ... other servers ... "aws-postgres-mcp-server": { "command": "node", "args": [ // Full path to the built index.js "C:\\Users\\NATH\\Documents\\Cline\\MCP\\aws-postgress-mcp-server\\build\\index.js" ], // Database credentials go in the 'env' object "env": { "DB_HOST": "YOUR_HOST.rds.amazonaws.com", "DB_PORT": "5432", "DB_NAME": "YOUR_DB_NAME", "DB_USER": "YOUR_DB_USER", "DB_PASSWORD": "YOUR_PASSWORD" }, "transportType": "stdio", "disabled": false, "autoApprove": [] } // ... other servers ... } }

Usage

Once configured, the client will start the server. Use the query tool:

<use_mcp_tool> <server_name>aws-postgres-mcp-server</server_name> <tool_name>query</tool_name> <arguments> { "sql": "SELECT table_name FROM information_schema.tables WHERE table_schema = 'public';" } </arguments> </use_mcp_tool>

Notes

The server only allows read-only queries (SELECT, SHOW, etc.).
To configure clients using npx @t1nker-1220/aws-postgres-mcp-server ..., the package must first be published to npm. The configuration would still use the env object for credentials.
