AI agents call get_property_price_index to retrieve information from Mcp Swiss without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves pre-computed statistical index data from a public source. It has no side effects, cannot modify data, and poses minimal risk if misused by an AI agent. The worst outcome would be unnecessary queries or information disclosure of already-public data.
