Description

Headless Eclipse Memory Analyzer Tool integration for Java heap dump analysis. Provides 6 core tools: healthcheck validation, predefined report generation (leak suspects, system overview, top components), OQL query execution with inline results, index status checking, generic command execution across 56 built-in MAT commands, and OQL syntax guidance. Features comprehensive security controls including path allowlists, query size limits, and process timeouts. Executes MAT via direct Java launcher invocation to avoid GUI dependencies.
