aviationweather.observation.pirep
Retrieve Pilot Reports (PIREPs) near a given ICAO station within a configurable radius and time window. PIREPs are real-time in-flight observations filed by pilots capturing actual icing severity, turbulence intensity, visibility, cloud bases and tops, and conditions at flight level. Returns deco...

What aviationweather.observation.pirep does on Apibase
AI agents call aviationweather.observation.pirep to retrieve information from Apibase 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 |
|---|---|---|---|
id | string | Yes | ICAO station identifier to use as the geographic center of the search (e.g. "KJFK", "KORD"). Pilot reports within `distance` nautical miles of this station and |
age | integer | — | How many hours back to search for pilot reports (1–24, default 2). |
distance | integer | — | Search radius in nautical miles around the station (10–200, default 100). 100 nm covers the typical terminal area plus en-route corridor. |

Attacks that exploit this kind of access
The rule that runs aviationweather.observation.pirep safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Apibase, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For aviationweather.observation.pirep, this is the rule to start with:
aviationweather.observation.pirep 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 Apibase, apply this rule, and every aviationweather.observation.pirep call is checked against it from then on.
Questions about aviationweather.observation.pirep
Retrieve Pilot Reports (PIREPs) near a given ICAO station within a configurable radius and time window. PIREPs are real-time in-flight observations filed by pilots capturing actual icing severity, turbulence intensity, visibility, cloud bases and tops, and conditions at flight level. Returns decoded fields: flight level, icing and turbulence extents, and raw PIREP text. Useful for pre-flight planning, route analysis, and verifying forecast accuracy. Source: NOAA Aviation Weather Center — US Government public domain, no auth required. It is categorised as a Read tool in the Apibase MCP Server, which means it retrieves data without modifying state.
aviationweather.observation.pirep accepts 3 parameters: id, age, distance. Required: id. The full parameter table on this page comes from the server's own tool schema.
Register the Apibase MCP server in PolicyLayer and add a rule for aviationweather.observation.pirep: 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 Apibase. Nothing to install.
aviationweather.observation.pirep 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 aviationweather.observation.pirep 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 aviationweather.observation.pirep. 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.
aviationweather.observation.pirep is provided by the Apibase MCP server (apibase-mcp-client). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
