LCA Skills runtime adapters

CLI and MCP operations for deterministic study checks plus bounded openLCA, Brightway, and GREET adapters.

Install the optional runtime

bash

python -m pip install -e .
python -m pip install -e ".[openlca]"
python -m pip install -e ".[brightway]"

Install only the adapters needed by the environment. The portable skills do not require the optional scientific packages.

Bundled MCP server

bash

python lca_tools/mcp_server.py

The bundled stdio server advertises 13 deterministic tools covering study creation/validation, balances, claims, result comparison, openLCA, Brightway, and GREET provenance/result ingestion.

Adapter boundaries

openLCA v0.2.0 adapter is read-oriented and does not create/mutate database entities.
Brightway adapter calculates existing activity/database identities and does not import databases or mutate exchanges.
GREET adapter creates provenance manifests and normalizes exported results; it is not a universal GREET execution engine.

Note

Runtime success is software evidence. It is not scientific qualification of the study.
