AI agents call get_route_static to retrieve information from Lviv Public Transport without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though get_route_static only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_route_static gives an agent. Each links to the full case and the policy that stops it:
Other read tools across the catalogue. The same approach applies to each: allow, with a rate cap to control cost.
Returns static route metadata: short and long name, vehicle type, brand colour, ordered stop lists for both directions, and route polylines (shapes) for map rendering. Use when the user asks which stops a route serves, what a route looks like on a map, or what the scheduled departure times are. Do NOT use this when live vehicle positions are needed — use get_route_realtime instead. Requires a route short name (e.g. "T30", "32A") or numeric external ID; call get_stops_around_location first if you only know a location and need to discover which routes serve it.. It is categorised as a Read tool in the Lviv Public Transport MCP Server, which means it retrieves data without modifying state.
Register the Lviv Public Transport MCP server in PolicyLayer and add a rule for get_route_static: 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 Lviv Public Transport. Nothing to install.
get_route_static 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 get_route_static 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 get_route_static. 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.
get_route_static is provided by the Lviv Public Transport MCP server (https://api.lad.lviv.ua/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
