- Seamless MCP server integration set up entirely from phone
- Automatic sync across devices via Git without separate sync management
- Cloud-native architecture keeps phone lightweight while running heavy jobs
| - Import-first approach: reads existing configs from all your tools and converges them before you write YAML
- No marketing gloss: capability table generated at build time from actual adapter code, not hand-maintained
- Portable across tools: single harness.yaml travels with you to every machine and tool
- Open source and free: no cost beyond existing Claude subscription
- Based on open specification: Harness Protocol is vendor-neutral and JSON Schema validated
