WHAT IT DOES

What secret-list does on Cargo

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

RISK

Why secret-list is rated Low

This tool retrieves secret metadata (names and associated information) without exposing actual secret values or modifying any data. However, secret names themselves can be sensitive reconnaissance data that reveals infrastructure details, authentication mechanisms, or integration points. An AI agent misusing this to enumerate secrets could inform targeted attacks, though the lack of value exposure limits damage.

From the tool's definition Tool description states 'Lists repository, organization, or environment secret names and metadata' - a retrieval operation. Explicitly notes 'Secret values are not exposed by GitHub', confirming no write or destructive capability.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs secret-list safely

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

secret-list Allowed

secret-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": {
    "secret-list": {}
  }
}

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

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

Can I rate-limit secret-list? +

How do I block secret-list completely? +

Set action: deny in the PolicyLayer policy for secret-list. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
