WHAT IT DOES

What archive_memory does on Cognio

AI agents use archive_memory to create or update resources in Cognio, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Cognio environment.

RISK

Why archive_memory is rated Medium

Although archiving removes a memory from active use, it is classified as Write rather than Destructive because soft deletion is inherently reversible—the data persists and can typically be restored.

From the tool's definition Tool name 'archive_memory' and description 'Archive (soft delete) a memory by ID' indicate a reversible modification of memory state.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs archive_memory safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Cognio, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For archive_memory, this is the rule to start with:

archive_memory Rate-limited

archive_memory stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Cognio, apply this rule, and every archive_memory call is checked against it from then on.

FAQ

What risk level is archive_memory? +

archive_memory is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit archive_memory? +

Yes. Add a rate_limit block to the archive_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.

How do I block archive_memory completely? +

Set action: deny in the PolicyLayer policy for archive_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.

What MCP server provides archive_memory? +
