WHAT IT DOES

What sample_probe does on CoWork OS

AI agents use sample_probe 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.

RISK

Why sample_probe is rated Medium

An AI agent can call sample_probe faster than any human can review: one bad instruction and it creates or modifies resources in CoWork OS by the hundred, each call as confident as the last.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs sample_probe 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 sample_probe, this is the rule to start with:

sample_probe Rate-limited

sample_probe 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.

How do I enforce a policy on sample_probe? +

Register the CoWork OS MCP server in PolicyLayer and add a rule for sample_probe: 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.

What risk level is sample_probe? +

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

Can I rate-limit sample_probe? +

Yes. Add a rate_limit block to the sample_probe 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 sample_probe completely? +
