Permanently delete one or more memories. This is irreversible: all stored data for that memory is removed. Returns the count of deleted memories.
AI agents call ragionex_delete_memory to permanently remove resources in Ragionex Memory MCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data with no recovery mechanism. While the blast radius is limited to memory records rather than financial or system-critical assets, the irreversible destruction of potentially important contextual data warrants a 'high' severity classification. Confidence is very high due to explicit destructive language in the description.
From the tool's definition Tool description explicitly states: 'Permanently delete one or more memories. This is irreversible: all stored data for that memory is removed.' The words 'permanently delete', 'irreversible', and 'all stored data...is removed' directly indicate destructive…
Attacks that exploit this kind of access
Permanently delete one or more memories. This is irreversible: all stored data for that memory is removed. Returns the count of deleted memories. It is categorised as a Destructive tool in the Ragionex Memory MCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Ragionex Memory MCP server in PolicyLayer and add a rule for ragionex_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 Ragionex Memory MCP. Nothing to install.
ragionex_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 ragionex_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 ragionex_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.
ragionex_delete_memory is provided by the Ragionex Memory MCP server (ragionex/memory-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
