Why list_taxes needs a policy

This tool performs a data retrieval operation with optional filtering/search and pagination—classic read semantics. There are no side effects, no code execution, no data modification, and no financial transactions. The word 'list' combined with 'pagination and optional search' confirms this is a query operation.

From the tool's definition Tool name 'list_taxes' and description 'List aviation taxes with pagination and optional search' indicate a read-only operation that retrieves and presents tax information without modifying, executing code, or causing destructive effects.

POLICY

How to control list_taxes

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_taxes:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_taxes": {}
  }
}

list_taxes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Aviationstack MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
