WHAT IT DOES

What session_checkpoint does on Enhanced Knowledge Graph Memory Server

AI agents use session_checkpoint 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_checkpoint is rated Medium

The tool creates/saves data (a checkpoint snapshot) in a reversible manner. It does not execute arbitrary code, delete data, move money, or read without side effects. The 'medium' severity reflects that a malicious checkpoint could capture and persist sensitive session state (memory, knowledge graph contents) for later misuse, but the operation itself is not inherently destructive or executable in scope.

From the tool's definition Tool creates a 'checkpoint snapshot of the current session state' — this is a write operation that creates a new persistent record. The description indicates state capture/storage without deletion or overwrite.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

session_checkpoint Rate-limited

session_checkpoint 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Enhanced Knowledge Graph Memory Server, apply this rule, and every session_checkpoint call is checked against it from then on.

FAQ

Questions about session_checkpoint

What does the session_checkpoint tool do? +

Create a checkpoint snapshot of the current session state for later restore. 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_checkpoint? +

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

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

Can I rate-limit session_checkpoint? +

Yes. Add a rate_limit block to the session_checkpoint 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_checkpoint completely? +

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

session_checkpoint 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.
