List available themes/categories in datos.gob.es (e.g., medio-ambiente, economia, salud, educacion).
AI agents call list_open_data_themes 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 and enumerates metadata (theme categories) from a public Spanish open data portal. It performs no creation, modification, deletion, code execution, or financial operations. The data accessed is already public and immutable. Misuse would have minimal impact—an agent could only enumerate available categories, which is informational. Classification as Read with low severity is appropriate.
From the tool's definition Tool name 'list_open_data_themes' and description state it 'List[s] available themes/categories' from a public data catalog. The verb 'list' combined with 'available themes' indicates a read-only query operation with no side effects.
