List airports with pagination and optional search.
AI agents call list_airports to retrieve information from Aviationstack MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries airport data with pagination and optional filtering. It performs no side effects, does not execute code or commands, does not modify data, and does not involve financial transactions. It is a straightforward read operation consistent with the 'Read' category.
From the tool's definition Tool name 'list_airports' and description 'List airports with pagination and optional search' indicate data retrieval only. No mutation, deletion, execution, or financial operations are possible.
Documented attack patterns abuse exactly the kind of access list_airports gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Aviationstack MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_airports:
{
"version": "1",
"default": "deny",
"tools": {
"list_airports": {}
}
}list_airports is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List airports with pagination and optional search. It is categorised as a Read tool in the Aviationstack MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Aviationstack MCP Server MCP server in PolicyLayer and add a rule for list_airports: 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 Aviationstack MCP Server. Nothing to install.
list_airports 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 list_airports 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 list_airports. 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.
list_airports is provided by the Aviationstack MCP Server MCP server (pradumnasaraf/aviationstack-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Aviationstack MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
