Measix Runcove: persistent MCP workspaces built on microsandbox

[topabomb]

Hi microsandbox community! I'm sharing Measix Runcove, a project I maintain whose source repository has just become public:

https://github.com/topabomb/measix-runcove

Runcove Server uses microsandbox as the engine for persistent user workspaces. It provides a Rust service layer for MCP clients, with:

• Persistent spaces, VM lifecycle management, idle shutdown and wake-up, and an administration API for users, credentials and resources.
• Command and file tools, browser automation, and a web desktop where a person can view the same browser and take control through a shared control lease.
• Access to the same workspace through MCP, the desktop file panel and WebDAV, plus temporary web publishing for files and applications.
• Docker/Compose deployment, offline packaging, backup and recovery procedures, and documented build provenance and verification results.

The repository also includes Runcove Standalone: one user and one workspace in a single container, sharing the application core but running without microsandbox or KVM. The microsandbox integration described here is the Server deployment.

A few boundaries: the currently validated image platform is Linux/amd64, and Server requires KVM. Server currently pins microsandbox 0.7.2 with documented downstream lifecycle and relay patches; compatibility with newer releases is not being claimed. The runtime notes describe those patches and their removal criteria. Documentation is currently in Chinese, with deployment instructions and version-specific validation records.

Thank you to the microsandbox maintainers and contributors for the microVM foundation and for your work on upstream fixes. I hope this is a useful example of building persistent agent workspaces on microsandbox. Feedback from others working on similar integrations would be very welcome!
