@rakyll (Jaana Dogan) announced github.com/agent-substrate/env (Apache-2.0): an isolated, snapshottable environment layer on Agent Substrate with ate-env CLI/API and guest daemon, plus a built-in MCP server exposing filesystem and shell tools so any MCP client can try Substrate without writing integration code first (API still alpha).

Key Takeaways

  • ✓Open-sourced agent-substrate/env: CLI, API, guest daemon, Go/Python clients.
  • ✓Built-in MCP for filesystem and shell — try with any MCP client.
  • ✓Substrate container actors: snapshot, schedule, multiplex idle envs; API still alpha.
