What acknowledge_mention does on CoWork OS
AI agents use acknowledge_mention to create or update resources in CoWork OS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CoWork OS environment.
Why acknowledge_mention is rated Medium
This tool performs a write operation by updating the status or state of a mention (likely marking it as acknowledged). It is reversible (the acknowledgment could be removed or changed), so it does not qualify as Destructive. There are no side effects like code execution, financial transactions, or data deletion.
From the tool's definition The tool 'acknowledge_mention' creates or modifies a state/status record (acknowledgment) for an existing mention, indicating the mention has been seen and will be worked on. This is a reversible create/modify action with no irreversible consequences.
Attacks that exploit this kind of access
The rule that runs acknowledge_mention safely
PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For acknowledge_mention, this is the rule to start with:
acknowledge_mention 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 CoWork OS, apply this rule, and every acknowledge_mention call is checked against it from then on.
Questions about acknowledge_mention
Acknowledge a mention, indicating you have seen it and will work on it. It is categorised as a Write tool in the CoWork OS MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the CoWork OS MCP server in PolicyLayer and add a rule for acknowledge_mention: 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 CoWork OS. Nothing to install.
acknowledge_mention is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the acknowledge_mention 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 acknowledge_mention. 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.
acknowledge_mention is provided by the CoWork OS MCP server (CoWork-OS/CoWork-OS). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
