Verdicts

Cursor CLI

Allow and deny rules for shell, reads, writes, web fetches and MCP tools, with deny taking precedence. No CLI changelog, and versions are dates.

GitHub Copilot CLI

Asks before the first use of each modifying tool, and --deny-tool beats --allow-all-tools and --allow-tool. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

Before you call either

Cursor CLI

  1. Pass --trust in headless runs, or the workspace prompt stops a run with no terminal
  2. Write deny rules in .cursor/cli.json before using --force. It runs any command they don't match
  3. Don't use --approve-mcps in repositories you didn't write. Two 2025 CLI advisories came through MCP
  4. Set CURSOR_API_KEY in CI. agent login opens a browser
  5. Record agent --version with each run. Versions are dates and there's no CLI changelog to compare against

GitHub Copilot CLI

  1. Pass --deny-tool for anything destructive. It wins over --allow-all-tools and --allow-tool
  2. Turn on the sandbox with /sandbox enable or --sandbox. It's off unless you opt in
  3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
  4. Run 1.0.88 or later where enterprise policy matters. Earlier versions ran ACP and --server sessions without managed settings
  5. Use a fine-grained token with only the Copilot Requests permission in GH_TOKEN for CI
