Why download_workflow_artifacts needs a policy

This tool retrieves pre-built artifacts from GitHub workflows, which is a read-only operation with no side effects. The artifact already exists and the action merely fetches it. While artifacts are outputs of executed workflows, the tool itself does not execute code or trigger operations—it only accesses and downloads existing data.

From the tool's definition Tool name 'download_workflow_artifacts' and description 'Download build artifacts' indicate retrieval of existing data with no modification, deletion, or execution.

POLICY

How to control download_workflow_artifacts

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 download_workflow_artifacts:

policy.json

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

download_workflow_artifacts 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.
