WHAT IT DOES

What workflows_featured_set does on Slack

AI agents use workflows_featured_set 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 workflows_featured_set is rated Medium

The tool name strongly suggests a write operation that modifies which workflows are featured in a Slack workspace. While the description is empty (reducing confidence), the naming convention and server context (full Slack access) indicate this creates or modifies workspace configuration. This is Write rather than Execute because it appears to set a configuration property rather than run arbitrary code.

From the tool's definition Tool name 'workflows_featured_set' suggests setting or modifying featured workflows in Slack. The parent server provides 'full access to Slack' including channels, messages, and workflows.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

workflows_featured_set Rate-limited

workflows_featured_set 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.
