Why copilot-test-generate needs a policy

This tool generates test code (text output) for review. It reads/analyzes the provided code and produces test suggestions. It does not execute code, modify files, or have side effects — it returns generated text. Severity is low as misuse only results in unhelpful or incorrect test suggestions.

POLICY

How to control copilot-test-generate

PolicyLayer is an MCP gateway — it sits between your AI agents and GitHub Copilot MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for copilot-test-generate:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "copilot-test-generate": {}
  }
}

copilot-test-generate 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 Copilot 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.
