meok-bs7121-mcp

BS 7121 lift-plan compliance for UK crane + hiab operators. Parts 1/3/4/5/7 clause lookup, AP competence, CPA Contract-Lift vs Hire triage, GBP calc, LOLER scheduling. By MEOK AI Labs.

Why this exists

BS 7121 is the UK lift-planning bible. Five parts most operators reference daily. Plus LOLER, PUWER, CDM 2015, CPCS. Mobile, tower, crawler, lorry-loader — every category has its own triage.

Real UK cases this MCP exists to prevent:

Brand Energy & Infrastructure Services UK — £1.6m HSE fine (Nov 2024). Jack Phillips (24) killed Eastbourne. Expired sling + missing exclusion zone.
Baldwins Crane Hire v Vision Modular Systems (ongoing 2026, £951k claim). CPA Condition 9(d) — proves Contract-Lift vs Hire triage at the QUOTE stage is the £100k+ wedge.

This MCP sits ABOVE 3D Lift Plan and Lolerflow — it doesn't simulate; it validates, classifies, and produces audit-quality compliance attestations.
