WHAT IT DOES

What ovapi-gtfs-feeds does on Meta Data Mcp

AI agents call ovapi-gtfs-feeds to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why ovapi-gtfs-feeds is rated Low

This tool performs a read-only operation (list) against open data APIs to retrieve information about available GTFS (General Transit Feed Specification) feed files. It has no side effects, does not execute code, does not modify data, and poses minimal risk if called by an AI agent. The blast radius is confined to data retrieval.

From the tool's definition Tool description states 'List the bulk GTFS zip and GTFS-RT protobuf feed files published' — a list operation that retrieves/queries publicly available transit data feeds without modifying or executing anything.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs ovapi-gtfs-feeds safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Meta Data Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For ovapi-gtfs-feeds, this is the rule to start with:

ovapi-gtfs-feeds Allowed

ovapi-gtfs-feeds is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "ovapi-gtfs-feeds": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every ovapi-gtfs-feeds call is checked against it from then on.
