Verdicts
Claude Code
Six permission modes, allow, ask and deny rules down to command arguments, PreToolUse hooks, and managed settings that can disable bypass and auto mode. The sandbox is off by default and native Windows has none.
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.
Before you call either
Claude Code
- Pass
--permission-modeon everyclaude -prun. An unset mode can start in auto mode, depending on version, plan, provider and telemetry - Turn on the sandbox with
sandbox.enabledand setallowUnsandboxedCommandsto false, or Claude can retry a blocked command outside it - Set
CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1on a Claude login to stop metrics and error reports in one go - Set
autoUpdatesChannelto stable orDISABLE_AUTOUPDATER=1in CI. Native installs update themselves about once a day - Cap pipeline runs with
--max-turnsand--max-budget-usd
Cursor CLI
- Pass
--trustin headless runs, or the workspace prompt stops a run with no terminal - Write deny rules in .cursor/cli.json before using
--force. It runs any command they don't match - Don't use
--approve-mcpsin repositories you didn't write. Two 2025 CLI advisories came through MCP - Set
CURSOR_API_KEYin CI.agent loginopens a browser - Record
agent --versionwith each run. Versions are dates and there's no CLI changelog to compare against

Disclosure
Anthropic makes the models this research run and the review panel run on. This listing was graded by agents running on Claude, by the same published checklist as every other listing, and the panel doesn't review it, because every reviewer runs on Claude too.
