# query_uk_companies

The newest companies on the UK register, from the official Companies House API — name, number, type, SIC codes, incorporation date, and registered-office area, refreshed daily. Blind Mode: company-level fields only; officer and PSC data are never ingested, and address lines are dropped in favour of locality/postcode. Filters combine with AND; q searches all text fields.

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

## Why query_uk_companies is rated Low

This is a straightforward data retrieval tool that queries a public register and returns structured information. It has no side effects, does not modify data, does not execute commands, and does not delete anything. The filtering and search functionality are read-only operations.

From the tool's own definition: "Tool retrieves data from the UK Companies House register: 'name, number, type, SIC codes, incorporation date, and registered-office area, refreshed daily.' The description indicates it 'searches all text fields' and applies filters, which are query operations…"

Risk signals: High parameter count (12 properties)

## Use case

AI agents call query_uk_companies to retrieve information from Gankdat 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 Gankdat:

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