Groundline Overview

Groundline MCP server exposes engine-test analysis through five MCP tools for opening runs, selecting analyses, verifying findings, and writing HTML reports. Deterministic analysis tools inspect phases, sensor health, redlines, valve response, oscillations, reference deviations, and pulse metrics while recording evidence. The verifier checks cited numbers, units, semantic roles, and reproducibility without exposing raw samples to an LLM. Reach for it when engine hot-fire or bench-test results need traceable, repeatable analysis.
