AI agents call get_breakdown 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 get_breakdown 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 get_breakdown gives an agent. Each links to the full case and the policy that stops it:

Consolidated breakdown tool. Pick dimension: 'channel' returns per-channel sessions/revenue/RPS plus engagement (visitors, avg dwell seconds, bounce rate) and bot_excluded_count (bot sessions removed from human metrics; a channel with sessions=0 but bot_excluded_count>0 is bot-only traffic, kept so it is not mistaken for 'no traffic') and — when ad spend is connected (Path B) — spend/ROAS/saturation; plus an 'Unattributed' row (is_unattributed=true) for purchase revenue not tied to any channel, with a revenue_breakdown summary (total_event_jpy/attributed_jpy/unattributed_jpy); pass filter.channel (e.g. 'google','meta','organic_search') to drill into that channel's campaigns (utm_campaign) with RPS/AOV/CVR. 'page' returns per-page pageviews/unique visitors/avg time/bounce ranked by pageviews (limit default 20, max 200; query strings stripped, bots excluded). 'session_attribute' returns the device / time-of-day (4h JST) / day-of-week (ISO) / new-vs-returning breakdowns in one call. site_id is OPTIONAL when OAuth-authenticated. Default period is the last 30 days; pass period='today'/'7d'/'90d' or a raw day count (1-365). filter only applies to dimension='channel'; limit only applies to dimension='page'.. 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 get_breakdown: 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.
get_breakdown 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 get_breakdown 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 get_breakdown. 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.
get_breakdown 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.
