Legalix Engineering & Tender MCP Service

An ultra-fast, production-ready Model Context Protocol (MCP) server connecting LLMs (ChatGPT, Claude, Cursor, and custom autonomous agents) to Israeli civil engineering databases, the Interministerial General Specification ("הספר הכחול" — all 48 chapters), Dekel pricing benchmarks (2026), and the Tender Arbitrage & Unbalanced Bidding Engine.

🌟 Key Features

⚡ Sub-Millisecond In-Memory Search: Indexed access to all 48 Blue Book chapters, 4,761 pages of measurement rules, and 2026 pricing benchmarks.
🏗️ 12 Engineering Consultant Disciplines: Deep retrieval for Structural (ת"י 466), Geotechnical (ת"י 940), Electrical, Plumbing (ת"י 1205), HVAC, Fire Safety, Acoustics (ת"י 1004), Accessibility (ת"י 1918), Green Building (ת"י 5281), and Infrastructure.
📊 Enterprise Excel BOQ Parser: Automatic extraction and cleaning of multi-sheet Israeli construction tenders (.xlsx, .xlsm, .xls, .csv), filtering out subtotal and summary rows.
💰 Tender Arbitrage Engine (Unbalanced Bidding): Mathematical cross-referencing between tender quantities and actual CAD Takeoff measurements to optimize profit and win probability.
🔌 Dual Protocol: Supports both Stdio MCP (native for Claude Desktop / ChatGPT Desktop / Cursor) and HTTP/REST Gateway (for Web Custom GPTs).

🚀 Quickstart & MCP Configuration

1. Claude Desktop / ChatGPT Desktop / Cursor (Stdio MCP)

Add the following to your MCP settings file (claude_desktop_config.json or ChatGPT Developer Settings):

{
  "mcpServers": {
    "legalix-engineering": {
      "command": "python3",
      "args": [
        "/path/to/legalix-engineering-mcp-repo/legalix_engineering_mcp_server.py"
      ]
    }
  }
}

2. HTTP / REST Gateway (For Web Clients & Cloudflare Tunnels)

Start the HTTP service on port 8090:

python3 legalix_engineering_mcp_http_bridge.py

Healthcheck: GET http://localhost:8090/health
Tool Definitions: GET http://localhost:8090/tools
RPC Executions: POST http://localhost:8090/
