WHAT IT DOES

What list_deploy_keys does on GitHub Repos Manager MCP Server

AI agents call list_deploy_keys to retrieve information from GitHub Repos Manager MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why list_deploy_keys needs a policy

This tool retrieves information about deploy keys (public keys used for automated deployments) without creating, modifying, or removing them. Listing configuration data is a read-only operation with no side effects. Severity is low because deploy key metadata is typically non-sensitive compared to secrets, and listing poses minimal risk even if misused by an agent.

From the tool's definition Tool name 'list_deploy_keys' and description 'List repository deploy keys' indicate retrieval/querying of existing deploy key metadata without modification or deletion.

POLICY

How to control list_deploy_keys

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_deploy_keys:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_deploy_keys": {}
  }
}

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

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