WHAT IT DOES

What get_schema does on StarTree MCP Server for Apache Pinot

AI agents call get_schema to retrieve information from StarTree MCP Server for Apache Pinot 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 get_schema needs a policy

This tool retrieves schema metadata from an Apache Pinot cluster. The verb 'Fetch' and the read-only nature of schema retrieval place it squarely in the Read category. There is no data modification, deletion, or execution of arbitrary operations. The severity is low because schema metadata is typically non-sensitive configuration information, and misuse poses minimal risk.

From the tool's definition Tool name 'get_schema' and description 'Fetch a schema by name' indicate a retrieval operation with no side effects.

POLICY

How to control get_schema

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_schema": {}
  }
}

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