forget_memory
AI agents call forget_memory to permanently remove resources in MemoryMesh — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The prefix 'forget' in the context of a memory/knowledge system typically means removing or purging stored information. Combined with the sibling tool 'forget_source' (which appears to delete indexed sources), this tool likely irreversibly removes memory records.
From the tool's definition Tool name 'forget_memory' strongly implies irreversible deletion of stored memory/data. The description is empty and uninformative, which lowers confidence, but the naming convention alongside sibling tools like 'forget_source' (which likely deletes indexed…
Attacks that exploit this kind of access
forget_memory. It is categorised as a Destructive tool in the MemoryMesh MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the MemoryMesh 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 MemoryMesh. Nothing to install.
forget_memory is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
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.
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.
forget_memory is provided by the MemoryMesh MCP server (kilhubprojects/memory-mesh). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
