MCP server for the Yerevan Municipality GIS portal — query air quality, cadastral parcels, zoning, construction and transport data from an AI agent. No API key required.
An MCP server that lets an AI agent query Yerevan's live municipal GIS data — air quality, parcels, zoning, construction, transport — with no API key.
This project wraps the Yerevan Municipality GIS portal (gis.yerevan.am) — an ArcGIS Enterprise 11.5 deployment with ~190 hosted layers and 300+ portal items — in a Model Context Protocol server, so a language model can answer real questions about the city from live data instead of guessing.
It exists because the portal is genuinely open: every layer this server touches is served anonymously, with no token, no account and no rate limit. That openness is buried behind an ArcGIS REST API with a bespoke unnamed projection, Armenian free-text categories, non-zero layer ids and numbers-encoded-as-strings. This server absorbs all of that so the model sees clean JSON, WGS84 coordinates and local timestamps.
It is intended for anyone building an AI assistant that needs to reason about Yerevan — urbanists, journalists, civic-tech developers, or a resident asking whether it is safe to go running today. Everything is read-only; the server never calls applyEdits.
