WHAT IT DOES

What oecd-list-codelist does on Meta Data Mcp

AI agents call oecd-list-codelist 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.

RISK

Why oecd-list-codelist is rated Low

This tool queries an OECD API to retrieve reference data (controlled vocabularies/codelists). It performs a simple data retrieval with no capability to modify, delete, execute code, or trigger external operations. The blast radius of misuse is minimal—an agent could only retrieve unwanted reference data, which poses no security risk.

From the tool's definition Tool name 'oecd-list-codelist' and description 'Fetch a codelist (controlled vocabulary) from the OECD SDMX API' indicate a retrieval operation.

RECOMMENDED RULE

The rule that runs oecd-list-codelist safely

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

oecd-list-codelist Allowed

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

  "tools": {
    "oecd-list-codelist": {}
  }
}

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

The button opens the PolicyLayer dashboard: create your workspace, connect Meta Data Mcp, apply this rule, and every oecd-list-codelist call is checked against it from then on.
