What it does
AX (Agent Executor) is a self-hosted distributed harness runtime from Google. It provisions isolated environments from suspendable/resumable images, runs harnesses and agents, and keeps durable execution state in an event log so work can resume after failure. It is compute-agnostic, with the best-documented path on Kubernetes via Agent Substrate. Official text says AX is not a managed service and not an agentic framework.
Agent-facing interfaces
- Interaction pattern: CLI + optional gRPC server
- Catalog protocols: GRPC, CLI
- MCP: ⚠️ Consumer, not a published MCP server
- Agent Skill: ⚠️ Hosted by the harness, not a published npx skills add package
- Onboarding type:
cli
How agents onboard
Interaction pattern: CLI + optional gRPC server
go install github.com/google/ax/cmd/ax@latest
ax --help
# Local built-in Antigravity harness (needs GEMINI_API_KEY or Vertex ADC)
ax --input "Can you list this directory?"
# Resume
ax --conversation <id> --input "Show me the contents of README.md"
ax --conversation <id> --resume
See the full onboarding section in the dossier.
