Cross exchange rate between two SEK currency-fixing series over a date range. series1 is the base, series2 the quote; the result is series1/series2 per day.

AI agents invoke cross_rates to trigger processes or run actions in Riksbank Se. Execute operations can have side effects beyond the immediate call -- triggering builds, sending notifications, or starting workflows. Rate limits and argument validation are essential to prevent runaway execution.
cross_rates can trigger processes with real-world consequences. An uncontrolled agent might start dozens of builds, send mass notifications, or kick off expensive compute jobs. PolicyLayer enforces rate limits and validates arguments to keep execution within safe bounds.
Execute tools trigger processes. Rate-limit and validate arguments to prevent unintended side effects.

These attack patterns abuse exactly the kind of access cross_rates gives an agent. Each links to the full case and the policy that stops it:
Other execute tools across the catalogue. The same approach applies to each: rate-limit and validate the arguments.
Cross exchange rate between two SEK currency-fixing series over a date range. series1 is the base, series2 the quote; the result is series1/series2 per day. Example: series1 "SEKEURPMI", series2 "SEKUSDPMI" gives EUR/USD derived from the SEK fixings. Provide from (required) and optionally to (both YYYY-MM-DD); omit to to run through the latest date. Use SEK currency series IDs ending in "PMI" (see list_series).. It is categorised as a Execute tool in the Riksbank Se MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Riksbank Se MCP server in PolicyLayer and add a rule for cross_rates: 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 Riksbank Se. Nothing to install.
cross_rates is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the cross_rates 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 cross_rates. 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.
cross_rates is provided by the Riksbank Se MCP server (https://gateway.pipeworx.io/riksbank-se/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
