WHAT IT DOES

What session_restore does on Enhanced Knowledge Graph Memory Server

AI agents use session_restore 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 session_restore is rated Medium

Restoring a session writes/overwrites current state with checkpoint data, which is a reversible modification (the checkpoint itself remains). This is a Write operation — it modifies the in-memory knowledge graph state — but is not Destructive since checkpoints are preserved and the action can be redone or undone by restoring a different checkpoint.

RECOMMENDED RULE

The rule that runs session_restore 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 session_restore, this is the rule to start with:

session_restore Rate-limited

session_restore 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 session_restore

What does the session_restore tool do? +

Restore a session from a previously created checkpoint. 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 session_restore? +

Register the Enhanced Knowledge Graph Memory Server MCP server in PolicyLayer and add a rule for session_restore: 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 session_restore? +

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

Can I rate-limit session_restore? +

Yes. Add a rate_limit block to the session_restore 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 session_restore completely? +

Set action: deny in the PolicyLayer policy for session_restore. 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 session_restore? +

session_restore 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.
