  "jsonrpc": "2.0",

## 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 own 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."

## Use case

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.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Slack:

```json

  "version": "1",
  "default": "deny",
  "tools": {
    "workflows_featured_set": {
      "limits": [
        {

          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
