Why list_secrets needs a policy

This is a Read operation as it retrieves and queries existing data (secret names) with no side effects. The severity is medium rather than low because knowing which secrets exist in a repository could inform targeted attacks or social engineering, even though the actual secret values are not exposed ('names only'). Confidence is high due to clear Read semantics in the description.

From the tool's definition Tool description states 'List repository secrets (names only)' - the verb 'list' and phrase 'names only' indicate retrieval without modification. However, the ability to enumerate secrets is sensitive.

Documented attack patterns abuse exactly the kind of access list_secrets gives an agent:

How to control list_secrets

PolicyLayer is an MCP gateway — it sits between your AI agents and GitHub Repos Manager MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_secrets:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_secrets": {}
  }
}

list_secrets is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

  1. Create a free account and register GitHub Repos Manager MCP Server — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
