Bernstein is an open-source governance layer for AI agents, distributed as an MCP server over stdio. It orchestrates multiple CLI coding agents through YAML-declared runs with phases, roles, and dependencies, and records byte-identical run receipts for audit.
Reach for it when you need deterministic, auditable orchestration of a crew of coding agents rather than running them ad hoc.
Use it to
- Declare multi-phase agent runs in YAML and execute them deterministically
- Enable audit mode and verify recorded run receipts
- Automate PRs, schedules, and chat bridges via operator commands
- Mark issues as open to volunteer compute for account-free contribution
- Run in an air-gapped environment
