WHAT IT DOES

What rollback_operation does on Enhanced Knowledge Graph Memory Server

AI agents use rollback_operation to create or update resources in Enhanced Knowledge Graph Memory Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Enhanced Knowledge Graph Memory Server environment.

RISK

Why rollback_operation is rated Medium

Rollback restores a previous state by overwriting current data, which is a reversible write operation (it doesn't permanently delete data, it restores a snapshot). However, it does overwrite the current state, making it high severity since an AI agent misusing this could silently undo legitimate changes across the knowledge graph.

RECOMMENDED RULE

The rule that runs rollback_operation safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Enhanced Knowledge Graph Memory Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For rollback_operation, this is the rule to start with:

rollback_operation Rate-limited

rollback_operation stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about rollback_operation

What does the rollback_operation tool do? +

Reverse a specific committed operation using its audit entry ID (restores entity to before-snapshot). It is categorised as a Write tool in the Enhanced Knowledge Graph Memory Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on rollback_operation? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for rollback_operation: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Enhanced Knowledge Graph Memory Server. Nothing to install.

What risk level is rollback_operation? +

rollback_operation is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit rollback_operation? +

Yes. Add a rate_limit block to the rollback_operation rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block rollback_operation completely? +

Set action: deny in the PolicyLayer policy for rollback_operation. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides rollback_operation? +

rollback_operation is provided by the Enhanced Knowledge Graph Memory Server MCP server (danielsimonjr/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
