CrudeCode (5 stars): a free toolkit that lets Claude or ChatGPT query state well filings and run decline curves and NPV.
CrudeCode is an Apache-2.0 MCP server that lets Claude or ChatGPT query state well filings with guarded SQL and run decline forecasts, valuation and maps. The repo is small, with one maintainer. It is a working upstream tool, not a pitch.
For upstream engineers: query well data and run decline and NPV economics in plain language.
