What lookup_airport does on Tanod
AI agents call lookup_airport to retrieve information from Tanod without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
code | object | — | ICAO, IATA or airport ident (such as RPLL, MNL or KSFO). Send code or query. |
limit | integer | — | Most query results (1-20). |
query | object | — | Name or city search (at most 100 characters). Send code or query. |
country | object | — | ISO 3166-1 alpha-2 country filter for query (such as PH). |
Parameters from the server's own tool schema.
Why lookup_airport is rated Low
Even though lookup_airport only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Risk signalsAccepts freeform code/query input (code)
Attacks that exploit this kind of access
The rule that runs lookup_airport safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Tanod, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For lookup_airport, this is the rule to start with:
lookup_airport is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Tanod, apply this rule, and every lookup_airport call is checked against it from then on.
Questions about lookup_airport
skypeek: Look up an airport by ICAO or IATA code or by name. For the distance between two use airport_distance. Returns an airport by ICAO, IATA or ident code (with runways: ends, length, width, surface, lighting, true headings; and radio frequencies), or up to 20 matches of a name or city search, optionally in one country: name, codes, type, position, elevation, country, region and municipality. Informational only: not for flight planning or navigation. Airports: OurAirports (public domain); the data may contain errors and no endorsement is implied. Answered from a bundled copy (no upstream call). A code with no airport is a 404 airport_not_found (not charged). Typically under 0.1 s (first call about 2 s). Price: USD 0.001. Free: 5 skypeek calls per IP per UTC day. Docs: https://tanod.dev/learn/airport-lookup-flight-distance-api.html. It is categorised as a Read tool in the Tanod MCP Server, which means it retrieves data without modifying state.
lookup_airport accepts 4 parameters: code, limit, query, country. The full parameter table on this page comes from the server's own tool schema.
Register the Tanod MCP server in PolicyLayer and add a rule for lookup_airport: 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 Tanod. Nothing to install.
lookup_airport 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 lookup_airport 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 lookup_airport. 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.
lookup_airport is provided by the Tanod MCP server (https://tanod.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
