THE RISK

What can go wrong

✕

Even read-only tools carry cost. An agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up bills.

POLICY

How to control Vtkapi

PolicyLayer is an MCP gateway — it sits between your AI agents and Vtkapi, and nothing reaches the server without passing your rules. These are the rules we recommend:

Cap read operations
{
  "vtk_get_class_action_phrase": {
    "limits": [
      {
        "counter": "vtk_get_class_action_phrase_per_minute",
        "window": "minute",
        "max": 60,
        "scope": "grant"
      }
    ]
  }
}

Controls API costs and prevents retry loops from exhausting upstream rate limits.

  1. Create a free account and register Vtkapi — nothing to install.
  2. Add these rules — paste them, or build them visually. Tune the limits to your setup.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about Vtkapi

Is the Vtkapi MCP server safe to use without restrictions? +

The Vtkapi server is primarily read-only with 18 read tools. While it cannot modify data, an agent in a retry loop can make thousands of API calls per minute, exhausting rate limits and running up costs. Rate limiting is still recommended.

How many tools does the Vtkapi MCP server expose? +

18 tools across 1 categories: Read. 18 are read-only. 0 can modify, create, or delete data.

How do I enforce a policy on Vtkapi? +

Register the Vtkapi MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.

Enforce policy on every Vtkapi tool call.

Deterministic rules across all 18 Vtkapi tools. Per-identity grants. Full audit log. Live in minutes. Nothing to install.
