venice_responses

THE RISK

High Risk

This tool wraps an AI responses API that includes tool/function-calling support, meaning it can invoke external tools and operations dynamically based on model outputs. This goes beyond a simple read or write — it can execute arbitrary downstream actions depending on what tools are registered and called.

From the tool's definition 'OpenAI-compatible Responses API. Single-turn or multi-turn with tool support' — the tool supports executing multi-turn interactions with tool use, meaning it can trigger external operations depending on arguments passed

HOW TO CONTROL VENICE_RESPONSES

PolicyLayer is an MCP gateway — it sits between your AI agents and Venice MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for venice_responses:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "venice_responses": {
      "limits": [
        {
          "counter": "venice_responses_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

venice_responses 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.

Create a free account and register Venice MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
