Eiffel Structural Prover MCP Connector for Claude

AI agents design structures that collapse under real-world loads. They design for the happy path. They estimate instead of calculating. They build monoliths and test nothing in isolation.

The Problem

LLMs commit five structural failures:

• Load Unanalyzed — 'Additional capacity will handle it.' Handle what? 4x normal volume during peak season? 10x when a major contract launches? What is the yield point of your processing capacity? At what concurrent workload does your cycle time breach the service commitment? Eiffel calculated wind force at every height of the tower — 7 tons per square meter at the summit. He did not say 'the structure should handle wind.'
• Modularity Absent — 'We run the entire operation as one unit.' A monolith. When one function fails, everything fails. When you need to update the verification step, you halt the entire workflow. The Eiffel Tower is 18,038 iron pieces — each manufactured off-site to 0.1mm tolerance, tested individually, assembled on-site. Can you test YOUR verification step without halting YOUR entire production line?
• Environment Ignored — 'Under normal conditions, the operation performs well.' Normal conditions are not the system. The Eiffel Tower's curved shape is an exponential function — calculated to minimize WIND force. Wind is the force nobody plans for until it bends the structure. Volume spikes (wind), seasonal variation (temperature), accumulated inefficiencies (corrosion), regulatory changes (seismic) — these are the forces that break structures. The happy path is not the architecture.
• Rigor Missing — 'The capacity should be big enough.' Based on what? Measured data or gut feeling? Eiffel calculated the position of every rivet. The tower deflects within centimeters of prediction. 'Should be enough' and 'roughly estimated' are not structural proof. Show: queuing theory for throughput, Amdahl's Law for parallelism limits, capacity model with measured inputs.
• Stakeholder Blind — 'This is too technical for the leadership team to understand.' When 300 artists signed a petition calling the tower a disgrace, Eiffel published his structural calculations in Le Temps newspaper. He showed the math. He translated engineering into public understanding. 'Trust us' is not stakeholder alignment.

How It Works

5 Decision Pivots following Eiffel's methodology:

1. loadAnalyzed — Static baseline, dynamic peaks, force concentration, structural limits per component.
2. modularityDesigned — Independent components with interfaces, testable in isolation, replaceable without rebuild.
3. environmentalForcesAccounted — Wind (spikes), temperature (seasonal), corrosion (accumulated debt), seismic (regulatory).
4. mathematicallyProven — Calculations with measured inputs, numeric results, safety margins.
5. stakeholderAligned — Bold decisions translated into business terms with evidence.

The Verdict Matrix

First Failing Pivot	Verdict	Meaning
loadAnalyzed = false	LOAD_UNANALYZED	Built without understanding forces.
modularityDesigned = false	MODULARITY_ABSENT	Monolith. Cannot test in isolation.
environmentalForcesAccounted = false	ENVIRONMENT_IGNORED	Happy path only. No storm planning.
mathematicallyProven = false	RIGOR_MISSING	Gut feeling, not calculation.
stakeholderAligned = false	STAKEHOLDER_BLIND	"Too technical to explain."
All pivots pass	STRUCTURE_PROVEN	Load-proven. Modular. Storm-tested. Calculated. Communicated.

Why It Works

• Tool calls are obligations. The agent cannot propose a structure without quantifying loads, defining modular boundaries, accounting for environmental forces, showing calculations, and demonstrating stakeholder alignment.
• Consistency engine catches contradictions. If the agent claims loadAnalyzed=true but says 'additional capacity will handle it,' the engine rejects — delegation is not analysis.
• Semantic traps detect structural laziness. 'Should be enough,' 'happy path,' 'gut feeling,' and 'too technical to explain' trigger automatic rejection.
