WHAT IT DOES

What vector-store-file-batch-cancel does on Universal OpenAI Vector Store MCP Server

AI agents invoke vector-store-file-batch-cancel to trigger actions in Universal OpenAI Vector Store MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

THE RISK

High Risk

Why vector-store-file-batch-cancel needs a policy

Cancelling a file batch is an active operation that triggers an external state change (stopping/aborting an in-progress batch operation) via the OpenAI API. It is not purely destructive (no data is deleted), but it executes an action with side effects on an external system. The blast radius is medium since cancelling a batch could interrupt ongoing operations and lose progress.

POLICY

How to control vector-store-file-batch-cancel

PolicyLayer is an MCP gateway — it sits between your AI agents and Universal OpenAI Vector Store MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for vector-store-file-batch-cancel:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "vector-store-file-batch-cancel": {
      "limits": [
        {
          "counter": "vector-store-file-batch-cancel_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

vector-store-file-batch-cancel stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
