AI agents call scf_get_risk_matrix 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 queries and retrieves existing risk matrix data (a read-only reporting view) without creating, modifying, or deleting any records. It aggregates organizational risk data for display purposes only, making it a straightforward Read operation with low severity due to no action capability.
From the tool's definition Tool name 'scf_get_risk_matrix' uses 'get', and description states 'Get the 5×5 risk matrix data' — retrieves data for visualization with no modification or side effects.
Attacks that exploit this kind of access

Register the Scf MCP server in PolicyLayer and add a rule for scf_get_risk_matrix: 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_risk_matrix 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_risk_matrix 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.
