AI agents call memcp_clear_context to permanently remove resources in Memcp — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly removes stored data (contexts and chunks). Deletion is a destructive action that cannot be undone. The blast radius is high because an AI agent with access could erase all persistent memory for a given context, eliminating historical knowledge and forcing loss of organized information.
From the tool's definition Tool name includes 'clear' and description states 'Delete a stored context and its chunks' — explicit deletion operation with no undo mechanism.
Documented attack patterns abuse exactly the kind of access memcp_clear_context gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Memcp, and nothing reaches the server without passing your rules. This is the rule we recommend for memcp_clear_context:
{
"version": "1",
"default": "deny",
"hide": [
"memcp_clear_context"
]
}memcp_clear_context disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a stored context and its chunks. It is categorised as a Destructive tool in the Memcp MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Me MCP server in PolicyLayer and add a rule for memcp_clear_context: 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 Memcp. Nothing to install.
memcp_clear_context 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 memcp_clear_context 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 memcp_clear_context. 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.
memcp_clear_context is provided by the Me MCP server (maydali28/memcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Memcp, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
