Get Git commits/changes for a build
AI agents call jenkins_get_build_changes to retrieve information from Mcp Jenkins without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical Git commit/change information associated with a Jenkins build. It queries existing data without modifying, deleting, or executing anything. The 'Get' verb and read-only nature of accessing build metadata classify it as Read category with low severity, as misuse would only expose information already in the system.
From the tool's definition Tool name is 'jenkins_get_build_changes' and description states 'Get Git commits/changes for a build' — both indicate a retrieval operation with no side effects.
