AI agents call list_sites to retrieve information from RevenueScope: Japanese EC RPS Benchmarks without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though list_sites only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access list_sites gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Return the sites available to this caller: my_sites (the authenticated user's own sites with display name + domain, so the assistant can match references like "the production site" or "revenuescope.jp" without the user copying a UUID) AND demo_sites (operator-provided showcase sites for exploring RevenueScope without connecting your own). When OAuth-authenticated, prefer my_sites and default analytics tools to the is_primary=true site when site_id is omitted. When NOT authenticated, my_sites is empty and you should use a demo_sites site_id (tell the user you are analyzing a sample/example site, not their own).. It is categorised as a Read tool in the RevenueScope: Japanese EC RPS Benchmarks MCP Server, which means it retrieves data without modifying state.
Register the RevenueScope: Japanese EC RPS Benchmarks MCP server in PolicyLayer and add a rule for list_sites: 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 RevenueScope: Japanese EC RPS Benchmarks. Nothing to install.
list_sites 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 list_sites 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 list_sites. 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.
list_sites is provided by the RevenueScope: Japanese EC RPS Benchmarks MCP server (https://mcp.revenuescope.jp/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
