AI agents call get_freight_rate_pressure to retrieve information from Risk Intelligence 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_freight_rate_pressure 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.

Returns freight rate pressure scores for major shipping and commodity indices (WCI, SCFI, BDI, CRB). Includes current values, week-over-week changes, z-score vs 52-week baseline, and mapping to trade corridors. WCI (Drewry World Container Index) tracks container rates in USD/FEU. SCFI (Shanghai Containerized Freight Index) tracks export rates from Shanghai. BDI (Baltic Dry Index) tracks dry bulk shipping rates. CRB (CRB Commodity Index) tracks broad commodity pressure. Pressure scoring: 0-35 STABLE, 36-55 ELEVATED, 56-69 VOLATILE, 70-84 SURGING, 85-100 EXTREME.. It is categorised as a Read tool in the Risk Intelligence MCP Server, which means it retrieves data without modifying state.
Register the Risk Intelligence MCP server in PolicyLayer and add a rule for get_freight_rate_pressure: 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 Risk Intelligence. Nothing to install.
get_freight_rate_pressure 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_freight_rate_pressure 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_freight_rate_pressure. 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_freight_rate_pressure is provided by the Risk Intelligence MCP server (https://www.supplymaven.com/api/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
