AI agents call compute_metric to retrieve information from Pensiata - Bulgarian Pension Fund Analytics 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 compute_metric 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 compute_metric gives an agent. Each links to the full case and the policy that stops it:

Compute a metric for Bulgarian pension funds or benchmark targets. Supports returns, drawdown, volatility, Sharpe/Sortino/Calmar, correlation, and benchmark-aware metrics over configurable period and frequency. Data freshness: computed from latest ingested FSC NAV and benchmark data.. It is categorised as a Read tool in the Pensiata - Bulgarian Pension Fund Analytics MCP Server, which means it retrieves data without modifying state.
Register the Pensiata - Bulgarian Pension Fund Analytics MCP server in PolicyLayer and add a rule for compute_metric: 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 Pensiata - Bulgarian Pension Fund Analytics. Nothing to install.
compute_metric 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 compute_metric 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 compute_metric. 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.
compute_metric is provided by the Pensiata - Bulgarian Pension Fund Analytics MCP server (https://mcp.pensiata.me/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
