The best answer I’ve come to thus far is the model we (estuary.dev) are building out now: offering mcp.estuary.dev with tools for creating a sandbox with our CLI pre-installed, a tool for requesting that a tightly scoped access token be injected into a named sandbox file (this is the approval gate), and a tool for executing arbitrary commands in the sandbox (presumably our flowctl CLI, but let the model rip).

The intent is that anybody can drive it from Claude/ChatGPT/Pi on their phone after MCP sign-in (oauth), the model has full computer use capability, but we can also leverage it to build guided agent workflows in our own dashboard.
