Search EU Regulations (EUR-Lex)
AI agents call search_eu_regulations to retrieve information from Open Legal Compliance MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though search_eu_regulations only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
