AI agents call scf_get_control 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 tool retrieves and queries control metadata from a reference catalog. No data is created, modified, deleted, or executed. The operation is read-only with no side effects, making it a straightforward Read category with low severity risk.
From the tool's definition Tool name 'scf_get_control' and description 'Get a single SCF control by ID. Returns description, mapped frameworks, assessment objectives, and linked evidence items' — uses 'Get' and 'Returns', indicating retrieval without modification.
Attacks that exploit this kind of access
Get a single SCF control by ID. Returns description, mapped frameworks, assessment objectives, and linked evidence items from the reference catalog. 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_get_control: 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_get_control 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_get_control 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_get_control. 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_get_control 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.
