WHAT IT DOES

What ai_apps_list does on Slack

AI agents call ai_apps_list to retrieve information from Slack without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why ai_apps_list is rated Low

This tool retrieves a list of AI apps available in the workspace, which is a read-only operation with no side effects. However, severity is raised to 'medium' rather than 'low' because the broader server context shows extensive Slack access (messages, channels, files, canvases, lists, search) and this tool could be used to enumerate security-relevant apps or attack surface.

From the tool's definition Tool name contains 'list' and description states 'List AI apps in the workspace', indicating data retrieval with no modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

ai_apps_list Allowed

ai_apps_list is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

  "default": "deny",
  "tools": {
    "ai_apps_list": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Slack, apply this rule, and every ai_apps_list call is checked against it from then on.
