THE RISK

Critical Risk

Why secret-delete needs a policy

This tool irreversibly removes GitHub Actions secrets, which are sensitive credentials stored in a repository or organization. Deletion cannot be reversed without manual re-creation. The blast radius is critical: an agent misusing this could remove all authentication secrets, breaking CI/CD pipelines and causing operational outages. This is a destructive operation with no undo capability.

From the tool's definition Tool name 'secret-delete' and description states 'Deletes a repository, organization, or environment GitHub Actions secret' — deletion is irreversible and cannot be undone.

POLICY

How to control secret-delete

PolicyLayer is an MCP gateway — it sits between your AI agents and Test, and nothing reaches the server without passing your rules. This is the rule we recommend for secret-delete:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "secret-delete"
  ]
}

secret-delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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

FAQ

Questions about secret-delete

What does the secret-delete tool do? +

Deletes a repository, organization, or environment GitHub Actions secret. It is categorised as a Destructive tool in the Test MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on secret-delete? +

Register the Test MCP server in PolicyLayer and add a rule for secret-delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Test. Nothing to install.

What risk level is secret-delete? +

secret-delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit secret-delete? +

Yes. Add a rate_limit block to the secret-delete rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block secret-delete completely? +

Set action: deny in the PolicyLayer policy for secret-delete. 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.

What MCP server provides secret-delete? +

secret-delete is provided by the Test MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Test tool call.

Start from Test, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
