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.\n\n**Muse Code.** Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.\n\n## Before you call either\n\n### Kiro CLI\n\n1. Set `KIRO_API_KEY` and pass `--no-interactive` with `--trust-tools=\u003clist\u003e` in pipelines. Keep `--trust-all-tools` for disposable environments\n2. Pass `--require-mcp-startup` when a run depends on MCP tools. Without it a failed server is logged and the run continues\n3. Pass `--no-interactive` whenever input is piped from a source you don't control, and run 2.10.0 or later on Windows\n4. Run `kiro-cli settings telemetry.enabled false` and turn off content collection on Free and individual plans. Both are on by default\n5. 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\n\n### Muse Code\n\n1. Set `META_API_KEY` for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts\n2. Gate on your own test command, not the exit code. `muse exec` returns 0 when the turn completes even if tests still fail\n3. Pass `--max-model-steps` on unattended runs so a stuck task can't loop\n4. Prefer `--disable-approval` to `--yolo` in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build\n5. Turn Contributor mode off in `/settings` before a subscription session touches private code\n\n## Questions\n\n### Which is better for AI agents, Kiro CLI or Muse Code?\n\nMuse Code scores 61.3 (C) on agent readiness against Kiro CLI's 59.9 (C), and leads in 4 of 7 scored categories. Kiro CLI leads on reliability, payments \u0026 pricing and transparency \u0026 trust.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/kiro-cli-vs-muse-code.json, and with the fewest tokens: https://www.anchorterminal.com/compare/kiro-cli-vs-muse-code.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"kiro-cli\", \"b\": \"muse-code\"}`.
