# Superserve

Gives your agent isolated Firecracker microVMs: create a sandbox, run a command, move files around. Useful when code has to run off your own machine.

## What it does

Superserve plugs into an MCP client and drives Superserve sandboxes. Locally it runs over stdio through `npx`, and each call targets a sandbox by `id`. There is also a hosted endpoint at `https://mcp.superserve.ai` over Streamable HTTP, so no local install is needed and the key travels as a bearer token.

The tool set is broad. `sandbox_create` spins up a sandbox and returns its `id`, `sandbox_exec` runs a shell command and hands back stdout, stderr and the exit code, while `sandbox_files_read` and `sandbox_files_write` handle files. `sandbox_computer` is the odd one out: it drives a GUI desktop with screenshots, mouse, keyboard, scroll and a live viewer URL. Pause, resume, kill, port publishing via `sandbox_preview_url` and outbound connection auditing are all there too.

Clients do not inherit `SUPERSERVE_API_KEY` from your shell, so it has to go into the `env` block of the config. The hosted endpoint takes a static bearer, but Claude.ai, the Custom Connector UI in Claude Desktop and ChatGPT developer mode expect OAuth, which it does not support yet. File reads reject anything over 1 MiB, and downloading a directory as a ZIP is capped at 10 MiB.

## Requirements
- Needs: Node.js (commands run via npx)
- Remote server: `https://mcp.superserve.ai`
- Environment variables: `SUPERSERVE_API_KEY`, `SUPERSERVE_BASE_URL` — keys and tokens: ask the human for the values, never commit them or put them in shared files.

## When to use it
- run untrusted code away from your own machine
- execute a shell command and capture its output
- read or write a file inside a sandbox
- publish a port and get a preview URL
- audit a sandbox's outbound connections

## Example prompts
- Create a sandbox and run `npm test` in it
- Write this script to a file in the sandbox and execute it
- Take a screenshot of the sandbox desktop and tell me what's on screen
