AI agents may call recall to permanently remove or destroy resources in Datos Cl. Without a policy, an autonomous agent could delete critical data in a loop with no way to undo the damage. PolicyLayer blocks destructive tools by default and requires explicit human approval before enabling them.

Without a policy, an AI agent could call recall in a loop, permanently destroying resources in Datos Cl. There is no undo for destructive operations. PolicyLayer blocks this tool by default and only allows it when a human explicitly approves the action.

Destructive tools permanently remove data. Block by default. Only enable with explicit approval workflows.

These attack patterns abuse exactly the kind of access recall gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so recall only ever does what you allow.

What does the recall tool do? +

Retrieve a value previously saved via remember, or list all saved keys (omit the key argument). Use to look up context the agent stored earlier — the user's target ticker, an address, prior research notes — without re-deriving it from scratch. Scoped to your identifier (anonymous IP, BYO key hash, or account ID). Pair with remember to save, forget to delete.. It is categorised as a Destructive tool in the Datos Cl MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on recall? +

Register the Datos Cl MCP server in PolicyLayer and add a rule for recall: 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 Datos Cl. Nothing to install.

What risk level is recall? +

recall is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit recall? +

Yes. Add a rate_limit block to the recall 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.

How do I block recall completely? +

Set action: deny in the PolicyLayer policy for recall. 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.

What MCP server provides recall? +

recall is provided by the Datos Cl MCP server (https://gateway.pipeworx.io/datos-cl/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Datos Cl tool call.
