mostlyright-data
Browse datasets built by our community or create your own with agents that find the sources and configure the pipeline. Mostly Right keeps the dataset live.
mostlyright-data is the command-line client. It opens hosted research sessions, starts and
follows hosted dataset runs, and downloads verified datasets after they finish.
Requirements
Use CPython 3.13.
Install
python -m pip install mostlyright-data
The default install is the hosted client. It works on Linux, macOS, and Windows.
Sign in
mr-data login
mr-data whoami
login stores a device key on the current machine. whoami checks that key.
Check the installation
mr-data --version
mr-data --help
Use mr-data research-open, mr-data research-status, and mr-data research-close for hosted
research sessions. research-status shows the current state.
Local execution
The local execution lane runs only on Linux:
python -m pip install "mostlyright-data[local]"
It is not required for the hosted client, and it is off by default: mr-data sends that work to
the backend. What still runs on this computer is catalog authoring, the search index, and the
commands that check a document or a run folder. A command with no backend lane refuses by name and
says why.
Documentation
Use mr-data --help for the full command list and options. Commands that support
--json write one JSON object.
--input-root and --output may use relative paths.
Behavior and limits
mr-data review RUN_DIR --localruns the deterministic checks and writes no review decision. It exits 1 when a check fails. Write the flag after the command name; before it,--localis the lane selector.mr-data review RUN_DIR --report REPORTseals a review decision from signed reviewer reports.- The weather reader accepts one extracted GRIB2 record. It refuses a multi-record GFS or HRRR file.
- Hosted credential-free acquisition supports one single-address public HTTPS object. Bounded collections require both local attestations.
Verification
make test-fast
make test-fast is non-authoritative and is useful while editing. make verify is required
before review or merge.
Development
uv sync --locked --extra dev
The local test suite requires Linux for worker-boundary tests. The hosted client is tested on Linux, macOS, and Windows.
