删除一条记忆。仅能删除自己的私有记忆（admin 可删除任何记忆）。
AI agents call delete_memory to permanently remove resources in Agent-Comm-Hub — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool performs irreversible deletion of memory records in a shared multi-agent communication system. Even though deletion is restricted to private memories for non-admin users, an AI agent with admin privileges or access to its own memory could permanently remove data that cannot be recovered.
From the tool's definition Tool name 'delete_memory' with description indicating deletion capability ('删除一条记忆' = 'delete a memory'). The description explicitly states memory deletion, with permission levels for private vs. admin access, confirming irreversible data removal.

删除一条记忆。仅能删除自己的私有记忆（admin 可删除任何记忆）。. It is categorised as a Destructive tool in the Agent-Comm-Hub MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Agent-Comm-Hub MCP server in PolicyLayer and add a rule for delete_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 Agent-Comm-Hub. Nothing to install.
delete_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 delete_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 delete_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.
delete_memory is provided by the Agent-Comm-Hub MCP server (liuboacean/agent-comm-hub). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
delete_memory is one line of Agent-Comm-Hub's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
