What done does on Cowork Bench
AI agents call done as a supporting operation in Cowork Bench workflows.
Why done is rated Low
This tool appears to be a signaling/completion marker used to indicate task completion in a benchmark context. It does not read, write, execute, delete data, or move money — it simply signals that the agent has finished. This falls into the 'Other' category as it has no direct data or system side effects beyond marking task state.
From the tool's definition Call this tool when the task is complete.
Attacks that exploit this kind of access
The rule that runs done safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Cowork Bench, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For done, this is the rule to start with:
done gets a rate cap, and everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Cowork Bench, apply this rule, and every done call is checked against it from then on.
Questions about done
Call this tool when the task is complete. It is categorised as a Other tool in the Cowork Bench MCP Server, which means it performs auxiliary operations.
Register the Cowork Bench MCP server in PolicyLayer and add a rule for done: 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 Bench. Nothing to install.
done is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the done 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 done. 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.
done is provided by the Cowork Bench MCP server (0717376/cowork_bench). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
