Lemma — Python SDK

Pure-Python SDK for the Lemma verification substrate. Ships as artano-lemma. Parallel to the Node distribution at ../mcp-server/ (@artano-ai/mcp-server). Both packages read the same shared cards/ corpus and the same schema/card.v0.1.json.

Why a Python SDK

Scientific researchers already work in Python (NumPy, SciPy, Jupyter, conda). A Python SDK lets a notebook call Lemma without spinning up a separate Node process and without going through the MCP protocol when in-process verification is enough.

Install

pip install artano-lemma            # from PyPI
pip install -e ".[dev]"             # local development

Commands

lemma paths        # show where cards/ and schema resolve
lemma list         # list every card
lemma show <id>    # print one card as JSON
