- The working repository sits in Katonic's GitHub Enterprise organisation, which cannot host public repositories; changes are merged there first.
- The public mirror is katonic-dev/leadgreen-ai: master is pushed there after every merge, GitHub Pages serves leadgreen.ai from it, and it is where issues and pull requests from outside are opened. A change accepted there is merged into the working repository and reaches the mirror on the next push.
- The project's other homes (the Hugging Face dataset, the Zenodo DOI, Wikidata) are set in build/projecttext.py; the build writes them into the pages' JSON-LD sameAs, CITATION.cff and .zenodo.json. build/hfdataset.py assembles and pushes the dataset.
Build
From this folder:
python build/build.pyIt renders every page and API file in memory first and refuses to write anything if a single {{PLACEHOLDER}} is unfilled or an em or en dash appears. Numbers on pages come only from build/data through placeholders defined in build/build.py; never type a figure into a page.
After any change to leadgreen-mcp/ or to the data, rebuild the wheel:
python -m pip wheel ./leadgreen-mcp -w dist --no-depsThe MCP server works with the mcp Python SDK 1.x and 2.x (guarded import in server.py). To exercise it, run any MCP client against python -m leadgreenmcp.server with PYTHONPATH=leadgreen-mcp and LEADGREENAPI_BASE set to the api/v1 folder; an example client script that checks the worked example (50 million tokens of Qwen 3 32B on H100 in Serbia = about 3,173 Wh and 2.12 kg CO2e) is described in the handover.
Preview: serve the folder locally, for example python -m http.server 8171 from the site root, so folder-style links resolve; opening the files directly also works for single pages.

Shortened. The full README is on GitHub.
