AI agents call get_disruptions to retrieve information from NS Travel Information MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries the NS railway network's disruption data and returns informational results. It has no side effects—it does not create, modify, delete, or execute operations. The read-only nature and purely informational purpose place it squarely in the Read category with low severity, as misuse would only expose existing public transit information.
From the tool's definition Tool retrieves information about disruptions ('Get comprehensive information about current and planned disruptions'); no modification, deletion, or execution of external operations.

PolicyLayer is an MCP gateway — it sits between your AI agents and NS Travel Information MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_disruptions:
{
"version": "1",
"default": "deny",
"tools": {
"get_disruptions": {}
}
}get_disruptions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
