What distance does on EU261 Flight Compensation
AI agents call distance to retrieve information from EU261 Flight Compensation 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 |
|---|---|---|---|
to | string | Yes | Destination IATA |
from | string | Yes | Origin IATA |
Parameters from the server's own tool schema.
Why distance is rated Low
This is a read-only operation that performs a mathematical calculation based on input coordinates/airport codes and returns computed results. It has no side effects, does not modify data, does not execute external operations, and does not involve financial transactions. The low severity reflects minimal risk from misuse—an agent cannot cause harm by calculating distances.
From the tool's definition Tool 'distance' calculates great-circle distance between airports and compensation band information. Keywords: 'calculate' and 'distance' indicate a pure computation returning derived data with no modifications, deletions, or external state changes.
Attacks that exploit this kind of access
The rule that runs distance safely
PolicyLayer is an MCP gateway: it sits between your AI agents and EU261 Flight Compensation, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For distance, this is the rule to start with:
distance 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 EU261 Flight Compensation, apply this rule, and every distance call is checked against it from then on.
Questions about distance
Calculate great-circle distance between two airports and the EU261 compensation band. It is categorised as a Read tool in the EU261 Flight Compensation MCP Server, which means it retrieves data without modifying state.
distance accepts 2 parameters: to, from. Required: to, from. The full parameter table on this page comes from the server's own tool schema.
Register the EU261 Flight Compensation MCP server in PolicyLayer and add a rule for distance: 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 EU261 Flight Compensation. Nothing to install.
distance 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 distance 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 distance. 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.
distance is provided by the EU261 Flight Compensation MCP server (https://eu261.danielsuchan.dev/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
