WHAT IT DOES

What add_slide does on Cowork Bench

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

RISK

Why add_slide is rated Medium

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

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_slide Rate-limited

add_slide 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.
