Runspace

Runspace is a command-line interface and MCP server that runs commands in disposable GitHub codespaces.

Runspace provides disposable cloud sandboxes for humans and AI agents, powered by GitHub codespaces. It executes commands, builds, and tests on a virtual machine rather than your local host machine. The tool functions as a command-line interface for users and an MCP server for AI agents, sharing the same underlying rules and commands. It handles tasks by creating a codespace, running commands, and returning outputs or patches for review. Users can create, execute, diff, copy, list, and delete sandboxes as needed.
