AI agents call scf_list_custom_risk_controls to retrieve information from Scf without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a query/retrieval operation that fetches existing data (controls associated with a custom risk) without modifying, executing, or deleting anything. The 'list' operation is a standard Read category action in the context of compliance control management. Low severity because unauthorized access to control metadata poses minimal immediate risk compared to actual control modification or deletion.
From the tool's definition Tool name contains 'list' and description indicates it 'returns' information about controls linked to a custom risk, with no mutation or side effects indicated.
Attacks that exploit this kind of access
List controls linked to a custom risk. Returns. It is categorised as a Read tool in the Scf MCP Server, which means it retrieves data without modifying state.
Register the Scf MCP server in PolicyLayer and add a rule for scf_list_custom_risk_controls: 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 Scf. Nothing to install.
scf_list_custom_risk_controls 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 scf_list_custom_risk_controls 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 scf_list_custom_risk_controls. 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.
scf_list_custom_risk_controls is provided by the Scf MCP server (mcp-server-scf). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
