Remove links from a Perspective by source, predicate, and/or target filter. Returns count of matched and removed links. Use to clean up outdated or incorrect memory entries.
AI agents call ad4m_delete_memory to permanently remove resources in Mcp Ad4m — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (memory links) from a persistent graph structure. Although the deletion is filtered (by source, predicate, target) rather than wholesale, it cannot be undone and represents a destructive operation.
From the tool's definition Tool description explicitly states 'Remove links from a Perspective' and 'matched and removed links'. The verb 'delete' in the tool name combined with 'remove' in the description indicates irreversible deletion of memory entries.
Attacks that exploit this kind of access
Remove links from a Perspective by source, predicate, and/or target filter. Returns count of matched and removed links. Use to clean up outdated or incorrect memory entries. It is categorised as a Destructive tool in the Mcp Ad4m MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp Ad4m MCP server in PolicyLayer and add a rule for ad4m_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 Mcp Ad4m. Nothing to install.
ad4m_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 ad4m_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 ad4m_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.
ad4m_delete_memory is provided by the Mcp Ad4m MCP server (thefranceway/mcp-ad4m). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
