WHAT IT DOES

What list_gists does on GitHub

AI agents call list_gists 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_gists is rated Low

Listing Gists is a read-only retrieval operation with no side effects. It queries existing data and returns results without altering state, triggering workflows, or affecting resources. The blast radius of misuse is minimal—an AI agent could enumerate gists but cannot modify, delete, or execute them via this tool alone.

From the tool's definition Tool name is 'list_gists' and description states 'List Gists' — a query operation that retrieves and enumerates Gists without modification, deletion, or execution.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_gists Allowed

list_gists 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": {
    "list_gists": {}
  }
}

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_gists call is checked against it from then on.
