WHAT IT DOES

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

AI agents call vector-store-file-content to retrieve information from Universal OpenAI Vector Store MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why vector-store-file-content needs a policy

This tool retrieves or queries file content from a vector store without modifying, deleting, or executing anything. It has no side effects and poses minimal risk if misused by an AI agent, as it only returns existing data. The blast radius is limited to information disclosure of files already stored in the vector store.

From the tool's definition Tool name is 'vector-store-file-content' and description states 'Get content of a specific file in a vector store' — the verb 'Get' and lack of any modification language clearly indicate a read-only retrieval operation.

POLICY

How to control vector-store-file-content

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-content:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "vector-store-file-content": {}
  }
}

vector-store-file-content is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
