Use when the user needs to run isolated code remotely — a disposable container, optional GPU access (T4 → H100), or a safer place for untrusted / heavy code. Prefer local execution for normal repo work; use Modal sandboxes for isolation, hardware access, or one-shot heavy compute.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modal Sandboxes
Disposable remote containers (with optional GPU) via Modal, paid per call in USDC. No Modal account, no GPU procurement.
**Base only in wallet mode; fine on an API key.** `sol.blockrun.ai` carries the `/v1/modal/*` routes but has no Modal backend
configured, so every action — create, exec, status, terminate — answers `503`. That reads
as "the sandbox service is down" rather than "wrong chain", which is exactly the wrong
conclusion to act on: retrying will not help. The tool checks the active chain first and
says so. Switch with `blockrun_wallet action:"chain" chain:"base"`. Prices below are Base
prices and include its per-transaction fee.
## READ THIS BEFORE SETTING `timeout`
**`timeout` is the BILLED lifetime, charged upfront in full, and never refunded — not an idle timeout.** Above 300s the price switches from a flat rate to **per-hour billing for the entire duration you ask for**, whether you use it or not. Terminating early refunds nothing.
That makes `timeout` the single most expensive field in this MCP:
| what you ask for | what you pay |
|---|---|
| `{ timeout: 300 }` | **$0.0110** |
| `{ timeout: 300, gpu: "A100" }` | **$0.2010** |

How to install
mdr add blockrunai/blockrun-mcp/modal@sha256:4c2404547ab6eed0The line at the top of this page pins the label git:20260905.a5f248d, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
