WHAT IT DOES

What list_discussions does on GitHub

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

RISK

Why list_discussions is rated Low

This tool queries and returns a list of discussions from a GitHub repository. It performs only a read operation—retrieving existing data without creating, modifying, deleting, or executing any operations. The blast radius of misuse is minimal, as an AI agent could only access discussion information already available to the authenticated user. No sensitive actions can be triggered through listing alone.

From the tool's definition Tool name 'list_discussions' and description 'List discussions' indicate a retrieval operation with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_discussions safely

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

list_discussions Allowed

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

  "tools": {
    "list_discussions": {}
  }
}

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

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