AI agents call getRepoDirectories to retrieve information from Github Repo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves directory information from a GitHub repository without modifying, deleting, or executing anything. It is a query/fetch operation with no side effects, fitting the Read category. Low severity due to limited blast radius—directory listings are typically non-sensitive metadata and read-only access poses minimal risk.
From the tool's definition Tool name 'getRepoDirectories' indicates it retrieves directory listings from a repository. Sibling tools 'getRepoAllDirectories' and 'getRepoFile' are clearly Read operations (fetching repo structure and file contents), suggesting this tool follows the same…
Documented attack patterns abuse exactly the kind of access getRepoDirectories gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Github Repo, and nothing reaches the server without passing your rules. This is the rule we recommend for getRepoDirectories:
{
"version": "1",
"default": "deny",
"tools": {
"getRepoDirectories": {}
}
}getRepoDirectories is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

getRepoDirectories. It is categorised as a Read tool in the Github Repo MCP Server, which means it retrieves data without modifying state.
Register the Github Repo MCP server in PolicyLayer and add a rule for getRepoDirectories: 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 Github Repo. Nothing to install.
getRepoDirectories is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the getRepoDirectories 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.
Set action: deny in the PolicyLayer policy for getRepoDirectories. 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.
getRepoDirectories is provided by the Github Repo MCP server (ryan0204/github-repo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Github Repo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
