How to Recover When an AI Agent Changes the Wrong Roblox Instances Through MCP
Stop the agent, compare against a checkpoint, classify the accidental changes, and restore only the affected instances/scripts before continuing. Do not ask the same agent to “undo everything” from memory if you have a reliable known-good state.

First preserve the bad state for diagnosis
Save the current diff or copy before restoring. You may need it to understand which instruction or scope rule allowed the agent to touch the wrong objects. Recovery without diagnosis invites the same mistake in the next session.
Restore from an external source of truth
Prefer version control, a saved project copy, or a known-good place/version. Conversation memory is not a reliable rollback mechanism because the agent may not remember every property, connection, or hierarchy edit it made.
Classify collateral changes
- Wrong script content.
- Wrong property values.
- Moved or deleted instances.
- Changed event/signal connections.
- Unexpected generated helper objects.
Tighten the next task boundary
After recovery, restate allowed read/write paths and require an operation plan before edits. If the agent needed broader context, expand read scope without automatically expanding write scope.
Working template
INCIDENT EXPECTED TASK: [...] WRONG CHANGES: [...] KNOWN-GOOD CHECKPOINT: [...] RESTORE: only affected items from checkpoint ROOT CAUSE: scope ambiguity / wrong target / dependency confusion / other NEXT SESSION: narrower write scope + operation plan first.
