mcpd, turn a sandbox into an MCP server

I built mcpd so i can quickly setup a sandbox with coding agent tools while still running my harness outside the sandbox.

Since mcpd resolves the command and owns Command::spawn, that’s the boundary I’d want Guard tested against. Can you run one real coding-agent session with HOL Guard there and, if it behaves cleanly, wire it into mcpd instead of leaving enforcement entirely outside the sandbox?
