"Hearth" matching MCP servers:

Enables ChatGPT to run a durable, sandboxed Windows workspace from a local MCP endpoint: spawning bounded commands, reading, writing, patching and undoing files with receipts, storing large output as artifacts, scheduling and waiting on durable jobs and closed typed scatter flows with per-conversation mailboxes, and driving desktop UI Automation. It also supports recipes, checkpoints, append-only event logs, and continuations, all backed by a single local SQLite database with strict schemas and localhost-only binding.
