WHAT IT DOES

What search_save does on Slack

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

RISK

Why search_save is rated Medium

The name 'search_save' implies persisting or saving a search query or configuration, which is a Write operation. However, the empty description significantly lowers confidence. It could also be Read if it merely saves state client-side, but saving data to a server is the most likely interpretation given the Slack MCP context.

From the tool's definition Tool name 'search_save' suggests saving a search; description is empty and uninformative.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs search_save safely

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

search_save Rate-limited

search_save 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 Slack, apply this rule, and every search_save call is checked against it from then on.
