Look up airport IATA codes by city name, airport name, or partial code. Use this to find the correct airport code before calling search_flights or get_date_grid. Returns matching airports with their IATA code, full name, city, and country.
AI agents call find_airport_code to retrieve information from Playwright Stealth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a lookup/query operation that retrieves airport information from a database. It performs no modifications, deletions, executions, or financial operations. The tool is explicitly positioned as preparatory for other flight operations (search_flights, get_date_grid), making its read-only nature clear.
From the tool's definition Tool description states it 'Look[s] up airport IATA codes' and 'Returns matching airports' — pure data retrieval with no side effects.
Documented attack patterns abuse exactly the kind of access find_airport_code gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright Stealth, and nothing reaches the server without passing your rules. This is the rule we recommend for find_airport_code:
{
"version": "1",
"default": "deny",
"tools": {
"find_airport_code": {}
}
}find_airport_code is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Look up airport IATA codes by city name, airport name, or partial code. Use this to find the correct airport code before calling search_flights or get_date_grid. Returns matching airports with their IATA code, full name, city, and country. It is categorised as a Read tool in the Playwright Stealth MCP Server, which means it retrieves data without modifying state.
Register the Playwright Stealth MCP server in PolicyLayer and add a rule for find_airport_code: 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 Playwright Stealth. Nothing to install.
find_airport_code 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 find_airport_code 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 find_airport_code. 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.
find_airport_code is provided by the Playwright Stealth MCP server (pulsemcp/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Playwright Stealth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
