Floor Area Ratio Calculator MCP Connector for Claude

Building Development Feasibility Analysis

The process of developing a property is complex. It requires coordinating multiple, often conflicting, zoning constraints--from how much ground area you can cover (Site Coverage) to the total bulk allowed over all floors (FAR), and ensuring enough space for water absorption (Permeability).

The Problem: Traditional planning assessments are manual, slow, and require an expert to track these three distinct metrics simultaneously. A developer might calculate a high FAR but fail because they neglected minimum permeable area requirements, or vice versa.

The Mechanism: This MCP connects your AI agent directly to the core formulas of urban planning law. It uses three specialized functions to assess viability:

1. max_site_coverage: Determines the maximum ground footprint allowed by zoning occupancy limits for a given plot size.
2. max_total_area: Calculates the total permitted floor area (FAR) across all stories, ensuring overall density compliance.
3. calculate_permeability: Verifies that enough open, non-impervious space remains after accounting for building foundations and meeting minimum green space mandates.

By chaining these tools, your agent can perform a complete, multi-faceted feasibility check in one workflow, identifying the most restrictive constraint immediately.

The Advantage: You get instant, quantitative compliance checks against complex municipal codes. This moves development planning from guesswork to guaranteed calculation support.
