WHAT IT DOES

What discussion-list does on Docker

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

RISK

Why discussion-list is rated Low

This tool queries GitHub's GraphQL API to retrieve discussion metadata (discussion number, title, author, category, answered status, comment count). It performs a read-only operation that retrieves existing data without creating, modifying, deleting, or executing any actions.

From the tool's definition Tool description states it 'Lists GitHub Discussions for a repository' and 'Returns structured list' — purely retrieving and presenting data with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs discussion-list safely

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

discussion-list Allowed

discussion-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": {
    "discussion-list": {}
  }
}

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

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