ask-openai · OpenAI Assistant MCP Server MCP: Risk & Policy

WHAT IT DOES

What ask-openai does on OpenAI Assistant MCP Server

AI agents invoke ask-openai to trigger actions in OpenAI Assistant 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.

WHY IT NEEDS A POLICY

Why ask-openai needs a policy

This tool sends queries to an external AI service (OpenAI's Chat Completion or Assistants API), which constitutes executing an external operation. The effects depend entirely on the arguments passed. While it is primarily a read-like operation (getting a response), it triggers real external API calls that may consume API credits and could be used to exfiltrate data or generate harmful content.

From the tool's definition "Ask my assistant models a direct question" — triggers an external API call to OpenAI's GPT models, executing a live inference operation with effects determined by the query arguments.
