# map_controls

Map ISO 27001 or NIST CSF controls to EU regulation articles. Returns a {results, meta} envelope: one cited row per control→regulation mapping with full/partial/related coverage, the applicable articles, notes, and a source_url/publisher/license _citation (article-anchored when the mapping targets a single article, instrument-level otherwise). Group rows by control_id for a per-control view; filter by control or regulation.

## Why map_controls is rated Low

This tool retrieves and presents pre-computed mappings between ISO 27001/NIST CSF controls and EU regulation articles. It performs read-only data retrieval with filtering and grouping capabilities. There are no side effects, data modifications, code execution, financial transactions, or destructive operations.

From the tool's own definition: "Tool description states it 'Map[s]' and 'Returns' mapping results with 'cited row per control→regulation mapping' and 'applicable articles'. The verbs are query/retrieval-oriented: 'Returns', 'Group rows', 'filter by control or regulation'."

## Use case

AI agents call map_controls to retrieve information from Eu Regulations 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 Eu Regulations:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "map_controls": {}
  }
}
```
