Switzerland Environmental Compliance MCP

Swiss environmental compliance data for agriculture via the Model Context Protocol. Water protection zones, buffer strips, ammonia emissions, biodiversity areas, nutrient loss targets, EIA thresholds, and soil contamination limits -- all from your AI assistant.

Part of Ansvar Open Agriculture.

Why This Exists

Swiss farms must comply with federal environmental regulations across several domains: Gewaesserschutz (GSchG/GSchV), ammonia emissions (LRV), Biodiversitaetsfoerderflaechen (DZV), the Pa.Iv. 19.475 nutrient loss reduction pathway, and UVP/VBBo for building permits and soil protection. These rules are published by BAFU, BLW, and Agroscope but scattered across ordinances, fact sheets, and cantonal guidance. This MCP server brings them together in a structured, searchable format.
