Switzerland Land & Woodland MCP

Swiss land law, forest protection, and spatial planning via the Model Context Protocol. Query BGBB land acquisition rules, Waldgesetz forest duties, RPG building zones, Fruchtfolgeflaechen quotas, and agricultural leases -- all from your AI assistant.

Part of Ansvar Open Agriculture.

Why This Exists

Swiss land and woodland law is spread across multiple federal acts (BGBB, WaG, RPG, LPG) and cantonal regulations. Farmers, notaries, and spatial planners need quick access to acquisition restrictions, forest clearing rules, building permits in agricultural zones, farmland protection quotas, and lease conditions. This MCP server makes all of it searchable.
