memory_unrelate

THE RISK

Critical Risk

This tool removes/deletes a relationship between two memories. Removing a relationship is a destructive action — it irreversibly severs a link that may not be easily reconstructed, especially in a vector/graph-based memory system. While it doesn't delete the memories themselves, the relationship metadata is deleted, which qualifies as Destructive rather than Write.

From the tool's definition UNRELATE UNLINK DISCONNECT - Remove a relationship between two memories. Keywords: unrelate, unlink, disconnect, detach, unbind, separate

HOW TO CONTROL MEMORY_UNRELATE

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP AI Memory, and nothing reaches the server without passing your rules. This is the rule we recommend for memory_unrelate:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "memory_unrelate"
  ]
}

memory_unrelate disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register MCP AI Memory — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

What does the memory_unrelate tool do? +

UNRELATE UNLINK DISCONNECT - Remove a relationship between two memories. Keywords: unrelate, unlink, disconnect, detach, unbind, separate. It is categorised as a Destructive tool in the MCP AI Memory MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on memory_unrelate? +

Register the MCP AI Memory MCP server in PolicyLayer and add a rule for memory_unrelate: 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 MCP AI Memory. Nothing to install.

What risk level is memory_unrelate? +

memory_unrelate is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit memory_unrelate? +

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

Set action: deny in the PolicyLayer policy for memory_unrelate. 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.
