Get available variables, optionally filtered by operation.
AI agents call get_ine_variables to retrieve information from Spanish Public Data MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available variables in the Spanish National Statistics Institute (INE) database. It performs no side effects, creates no data, executes no external operations, and causes no irreversible changes. It is purely informational—listing what statistical variables exist, possibly filtered by a specific operation.
From the tool's definition Tool name 'get_ine_variables' and description 'Get available variables, optionally filtered by operation' indicate data retrieval with no modification or deletion.
