Which one, for what

Cursor CLI F

Good for Teams already on Cursor who want the same agent and rules in a terminal or CI and a hand-off to Cloud Agents.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

No CLI changelog, and versions are dates

Kiro CLI C

Good for Teams on AWS that want one agent configuration across terminal, IDE and web, with central permission policy, prompt logging to their own S3 bucket and IAM Identity Centre sign-in.

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.

Kiro CLI

Permission rules follow deny over ask over allow, cloned repositories can't add rules, and a headless session treats every ask as a deny. Content from Free and individual paid accounts is used for service improvement, including model training, unless the user opts out, and API keys for pipelines need a paid plan.

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

Kiro CLI

  1. Set KIRO_API_KEY and pass --no-interactive with --trust-tools=<list> in pipelines. Keep --trust-all-tools for disposable environments
  2. Pass --require-mcp-startup when a run depends on MCP tools. Without it a failed server is logged and the run continues
  3. Pass --no-interactive whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows
  4. Run kiro-cli settings telemetry.enabled false and turn off content collection on Free and individual plans. Both are on by default
  5. Export variables in the shell before starting. Since 2.24.0 a project .env file is no longer loaded into sessions, MCP servers or tools

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
