forget_memory

THE RISK

Critical Risk

This tool permanently deletes stored memory data and associated index entries without apparent undo capability. While the blast radius is limited to indexed memories within a codebase intelligence system (not production data or financial systems), the irreversible nature of deletion and potential impact on code understanding workflows justifies the Destructive category.

From the tool's definition Tool description states 'Delete a memory by name. Removes the file and its index entries.' The verbs 'delete' and 'removes' directly indicate irreversible data deletion.

HOW TO CONTROL FORGET_MEMORY

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

policy.json

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

forget_memory 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 Reporecall — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

What does the forget_memory tool do? +

Delete a memory by name. Removes the file and its index entries. It is categorised as a Destructive tool in the Reporecall 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 forget_memory? +

Register the Reporecall MCP server in PolicyLayer and add a rule for forget_memory: 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 Reporecall. Nothing to install.

What risk level is forget_memory? +

forget_memory 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 forget_memory? +

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

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

forget_memory is provided by the Reporecall MCP server (proofofwork-agency/reporecall). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Reporecall tool call.
