## MCP tools (2)

### `run_python` (~172 tokens)

Run Python in a micro-VM

Run Python code in a sandbox: a local Hyperlight micro-VM, isolated from this machine by a hypervisor.
Variables, imports and functions persist from one call to the next, as in a notebook, until reset_sandbox. The result is what the code prints, then the value of a trailing expression after `Out:`.
The sandbox has CPython 3.12 with numpy, pandas, scipy, scikit-learn, matplotlib, pillow and requests.
Network: none, every connection is refused.
Files: the sandbox has its own filesystem, and none of this machine's files.
A call that runs longer than 30 seconds is stopped. That, or a crash, restarts the sandbox, and the variables of earlier calls are lost.

Input parameters:

- `code` (string, required): The Python code to run

### `reset_sandbox` (~72 tokens)

Reset the sandbox

Replace the sandbox with a fresh one, in milliseconds: variables and imports are gone. It first waits for calls still running or sent before it, each of which runs for at most 30 seconds, then for the restart one that ran out of time needs; longer while the sandbox first starts, its image pulled.

## Common questions

### What is the Hyperlight MCP server?

Hyperlight is an MCP server listed in the public MCP registry as io.github.hyperlight-dev/mcp-server-hyperlight. Runs Python in a local, hardware-isolated micro-VM that keeps its state between calls. This page covers its PyPI package (mcp-server-hyperlight).

### Is the Hyperlight MCP server safe to use?

Hyperlight scores 73 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 4 November 2026. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Hyperlight MCP server expose?

Hyperlight exposes 2 tools: run_python, reset_sandbox. Their descriptions and schemas cost roughly 244 tokens of context every time the server is loaded.

### Is the Hyperlight MCP server still maintained?

Hyperlight is still listed as active in the MCP registry. We last reached this channel on 4 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Hyperlight MCP server under?

Hyperlight declares the Apache-2.0 licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
