Run the demo
The repository includes a small Model Context Protocol server under demo/. It is intentionally
messy so a check has real findings. MCMR does not change it unless you request repairs.
Install MCMR and clone the repository with standard Python 3.14+.
pip install mcmrgit clone https://github.com/phvv-me/mcmr.gitRun every enabled lane and write the results to a local DataHub instance.
OPENROUTER_API_KEY="..." \DATAHUB_GMS_URL="http://localhost:8080" \mcmr check mcmr/demo --contextual --external --writeback --report-onlyRun the same command again to add another point to each assertion timeline. Then read the history.
mcmr history mcmr/demoUse --no-contextual when you want a fast and repeatable local run. The demo README contains its
smoke command and prepared stages. The DataHub pages explain
what writeback stores.
