Class CheckConnectionTool

java.lang.Object

org.gridgain.internal.mcp.tools.CheckConnectionTool

public class CheckConnectionTool
extends Object

MCP tool for validating GridGain database connectivity and health.

This tool performs a quick connection check by executing a simple SELECT 1 query against the configured GridGain cluster. It supports flexible connection configuration through a three-tier fallback mechanism: tool arguments, environment variables, and defaults.

Connection Configuration Priority

1. Tool Arguments: Connection parameters explicitly passed by the LLM
2. Environment Variables: Server-level configuration (GRIDGAIN_HOST, GRIDGAIN_PORT, etc.)
3. Default Values: Localhost defaults for development
