AI agents call audit_taxonomy 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 audit_taxonomy 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.

These attack patterns abuse exactly the kind of access audit_taxonomy gives an agent. Each links to the full case and the policy that stops it:

Audit the actor role taxonomy: compare model-defined roles vs deployed roles in the database. Returns per-regulation analysis showing: - model_only: roles the enrichment model can produce but aren't in the DB yet (gap) - deployed_only: roles in the DB but not in the model (unexpected — data quality issue) - role_counts: each deployed role with obligation count - known_issues: overlaps, naming issues, investigation items Use this for QA validation of the actor role taxonomy. Requires admin API key. No parameters needed — returns full corpus audit.. It is categorised as a Read tool in the Velvoite — EU Financial Regulatory Compliance MCP Server, which means it retrieves data without modifying state.
Register the Velvoite — EU Financial Regulatory Compliance MCP server in PolicyLayer and add a rule for audit_taxonomy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Velvoite — EU Financial Regulatory Compliance. Nothing to install.
audit_taxonomy is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the audit_taxonomy rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for audit_taxonomy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
audit_taxonomy is provided by the Velvoite — EU Financial Regulatory Compliance MCP server (https://mcp.velvoite.eu/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
