## Why oecd-get-datastructure is rated Low

This tool retrieves structural metadata about OECD datasets—essentially querying a definition or schema. It produces no side effects, does not modify data, does not execute code or external operations, and does not delete anything. The action is purely informational retrieval from an open data API, consistent with the 'Read' category (get/fetch/query).

From the tool's own definition: "Tool name 'oecd-get-datastructure' and description 'Get an OECD data-structure definition (DSD) describing dimensions and attributes' indicate retrieval of schema/metadata from a public API with no modification or execution capability."

## Use case

AI agents call oecd-get-datastructure to retrieve information from Meta Data Mcp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Meta Data Mcp:

```json
