WHAT IT DOES

What drafts_list does on Slack

AI agents call drafts_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 drafts_list is rated Low

This tool retrieves draft messages that have not been sent. It has no side effects—it does not create, modify, delete, execute code, or move money. While drafts may contain sensitive information, the operation itself is purely informational.

From the tool's definition Tool name 'drafts_list' and description 'List all unsent message drafts' indicate retrieval of data with no modification or deletion. The verb 'list' is explicitly a Read operation per the classification rules.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

drafts_list Allowed

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

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "drafts_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 drafts_list call is checked against it from then on.
