Tester's MCP bulk edit wiped 104 test cases' screenshot evidence; 12-hour recovery

A software tester recounts the scariest day of their career after using MCP to bulk-fix test records in Jira/Xray.
After the team's AI review flagged 104 completed SIT test cases where expected results had been copied into actual results, the author used MCP to batch-correct them—only for the operation to delete all attached screenshot evidence. Jira rollback failed and the lead gave two days to redo everything manually. salvation came from Windows retaining local screenshots: by matching them against Jira audit log timestamps, the author restored all 104 test cases in about 12 hours. Lesson, in their words: never touch test execution data with MCP again without a backup—a cautionary tale for anyone letting agents bulk-edit production data.
