WHAT IT DOES

What register_ref does on Enhanced Knowledge Graph Memory Server

AI agents use register_ref 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 register_ref is rated Medium

This tool creates or modifies index entries by registering aliases. It is reversible (aliases can be updated or removed) and has no capability to delete data, execute code, or cause financial impact. The blast radius of misuse is minimal—registering an incorrect alias would simply create a wrong pointer that could be corrected.

From the tool's definition Tool registers or creates a stable alias pointing to an entity name in a RefIndex. The action is creating/storing a reference mapping, which is a data modification operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

register_ref Rate-limited

register_ref 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.

LIMIT THIS TOOL → Instant setup, no code required.

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

FAQ

Questions about register_ref

What does the register_ref tool do? +

Register a stable alias (ref) pointing to an entity name in the RefIndex for O(1) lookups. 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 register_ref? +

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

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

Can I rate-limit register_ref? +

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

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

register_ref 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.
