What snow_blast_radius_dependents does on Serac
AI agents call snow_blast_radius_dependents to retrieve information from Serac without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why snow_blast_radius_dependents is rated Low
The tool retrieves dependency relationships across the ServiceNow instance. It reads and reports which artifacts depend on a given artifact, but does not modify, delete, or execute anything. Severity is medium because it exposes a broad map of system interdependencies, which could inform targeted attacks or misuse, but the tool itself causes no harm.
From the tool's definition 'Find every artifact across the instance that uses, calls, or depends on a given artifact' — this is a discovery/query operation with no side effects

The rule that runs snow_blast_radius_dependents safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Serac, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For snow_blast_radius_dependents, this is the rule to start with:
snow_blast_radius_dependents is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Serac, apply this rule, and every snow_blast_radius_dependents call is checked against it from then on.

Register the Serac MCP server in PolicyLayer and add a rule for snow_blast_radius_dependents: 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 Serac. Nothing to install.
snow_blast_radius_dependents 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 snow_blast_radius_dependents 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 snow_blast_radius_dependents. 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.
snow_blast_radius_dependents is provided by the Serac MCP server (serac-labs/serac). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
