  "summary": "Local sandbox for Mac that runs AI agents and their code in an isolated Apple container VM, exposed to clients as an MCP server.",
  "description": "Needs macOS on Apple Silicon and Python 3.10+; install by cloning the repo and running `./install.sh`. The MCP server is at http://coderunner.local:8222/mcp (or http://127.0.0.1:8222/mcp in no-network mode). Claude Code can run inside the sandbox, and there is a proxy for Claude Desktop. Sandboxed code has unrestricted network access by default; set `CODERUNNER_NETWORK=none` at install time to cut it off. The container can be stopped and resumed with its files and packages kept. Apache-2.0. Made by InstaVM, which also offers hosted VMs for agents.",
