Run shell commands and Python in a sandbox, to compute results from files rather than estimating them, with read-only access to uploaded files and a working directory to write to.
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
# Sandbox
Run code to compute results from files. What is mounted, how much is in
each mount, and which packages are installed are described separately, per
request.
## When to use the sandbox
Use it if **any** of these is true:
- The task references uploaded files.
- The task asks for a number, count, table, or other value derived from
data.
- You were about to state a computed result without actually computing it.
Do NOT use it if **any** of these is true:
- The question is about definitions, explanations, or concepts.
- The answer is already stated in the conversation.
- The task is to write code for the user to run, not to execute code
yourself.
- The task is vague ("analyze the files", "take a look") with no concrete
question. Ask the user what they want to know before running anything.
## Tools
- `run(command)` — run a shell command. `command` is either a single
string (run via `sh -c`) or a list of strings (executable first, then
one element per argument).
- `run_python(script)` — run a Python script. `script` is the full source
as one string.
- `read_image(path)` — look at an image in the sandbox. Only in rooms

How to install
mdr add soliplex/soliplex/bwrap_sandbox@sha256:b569ce1628ca0964The line at the top of this page pins the label git:20260928.9f44fd2, 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.
