AI agents call get_actor_roles to retrieve information from Velvoite — EU Financial Regulatory Compliance without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_actor_roles only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Get available actor roles per regulation with obligation counts. Actor roles define WHO an obligation applies to within a specific regulation (e.g. 'credit_institution', 'significant_institution' for CRD/CRR, or 'ai_provider', 'high_risk_deployer' for AI Act). Use this to discover which roles exist before filtering obligations with get_obligations(actor_role=...). Returns roles grouped by regulation, sorted by obligation count. Each role includes a human-readable label and description. Args: regulation: Filter to a specific regulation code (e.g. 'dora', 'ai_act'). If omitted, returns roles for all regulations.. It is categorised as a Read tool in the Velvoite — EU Financial Regulatory Compliance MCP Server, which means it retrieves data without modifying state.
