Show disk usage of Screaming Frog's internal crawl storage.
AI agents call storage_summary to retrieve information from Screaming Frog without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns disk usage statistics about existing crawl storage. It retrieves data without side effects, making it a Read operation. The severity is low because disk usage information is non-sensitive operational metadata that cannot be exploited to cause damage.
From the tool's definition Tool description states 'Show disk usage of Screaming Frog's internal crawl storage' — purely informational retrieval with no modification, deletion, or execution capability.
Attacks that exploit this kind of access
Show disk usage of Screaming Frog's internal crawl storage. It is categorised as a Read tool in the Screaming Frog MCP Server, which means it retrieves data without modifying state.
Register the Screaming Frog MCP server in PolicyLayer and add a rule for storage_summary: 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 Screaming Frog. Nothing to install.
storage_summary 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 storage_summary 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 storage_summary. 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.
storage_summary is provided by the Screaming Frog MCP server (marykovziridze/screaming-frog-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
