Get active navigational warnings from NGA Maritime Safety. Optional: navarea (I-XVI).
AI agents call intel_nav_warnings to retrieve information from Threat Intelligence MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves publicly available navigational warning data from NGA Maritime Safety. It performs a read-only query operation with optional filtering by navarea. There are no side effects, data modifications, code execution, financial transactions, or destructive actions.
From the tool's definition Tool description states 'Get active navigational warnings from NGA Maritime Safety.' This is a retrieval/query operation with no modification, deletion, or execution of external systems.
Documented attack patterns abuse exactly the kind of access intel_nav_warnings gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Threat Intelligence MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for intel_nav_warnings:
{
"version": "1",
"default": "deny",
"tools": {
"intel_nav_warnings": {}
}
}intel_nav_warnings is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get active navigational warnings from NGA Maritime Safety. Optional: navarea (I-XVI). It is categorised as a Read tool in the Threat Intelligence MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Threat Intelligence MCP Server MCP server in PolicyLayer and add a rule for intel_nav_warnings: 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 Threat Intelligence MCP Server. Nothing to install.
intel_nav_warnings 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 intel_nav_warnings 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 intel_nav_warnings. 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.
intel_nav_warnings is provided by the Threat Intelligence MCP Server MCP server (marc-shade/world-intel-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Threat Intelligence MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
