AI agents call incoterms_lookup to retrieve information from FreightUtils MCP Server 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 incoterms_lookup 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.

Look up Incoterms 2020 trade rules. Incoterms define who pays for what in international trade — transport, insurance, customs clearance, and risk transfer. There are 11 rules: 7 for any transport mode (EXW, FCA, CPT, CIP, DAP, DPU, DDP) and 4 for sea/inland waterway only (FAS, FOB, CFR, CIF). Use this tool when you need to: - Explain what an Incoterm means (e.g., "What does FOB mean?") - Compare seller vs buyer responsibilities - Determine risk and cost transfer points - Check which Incoterms apply to sea freight vs any mode. It is categorised as a Read tool in the FreightUtils MCP Server MCP Server, which means it retrieves data without modifying state.
Add a rule in your Intercept YAML policy under the tools section for incoterms_lookup. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the FreightUtils MCP Server MCP server.
incoterms_lookup 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 incoterms_lookup rule in your Intercept 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 Intercept policy for incoterms_lookup. 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.
incoterms_lookup is provided by the FreightUtils MCP Server MCP server (freightutils-mcp). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
