WHAT IT DOES

What describe_data does on TinyFn

AI agents call describe_data to retrieve information from TinyFn without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameters from the server's own tool schema.

RISK

Why describe_data is rated Low

This tool retrieves statistical information (descriptive statistics) from a dataset. It has no side effects, does not modify data, execute code, delete anything, or involve financial transactions. It is a pure information-retrieval operation consistent with the Read category. Low severity due to minimal blast radius if misused by an AI agent.

From the tool's definition Tool name 'describe_data' and description 'Get descriptive statistics for a dataset' indicate a read-only operation that queries and analyzes data without modification, creation, or deletion.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs describe_data safely

PolicyLayer is an MCP gateway: it sits between your AI agents and TinyFn, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For describe_data, this is the rule to start with:

describe_data Allowed

describe_data is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

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

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect TinyFn, apply this rule, and every describe_data call is checked against it from then on.
