## Facts

- Tool: `news`
- Server: MetaTrader5 MCP Server (`emerzon/mt-data-mcp`) — https://policylayer.com/tools/emerzon-mt-data-mcp.md
- Homepage: https://github.com/emerzon/mt-data-mcp
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "news",
    "arguments": {}
  }
}
```

## Why news is rated Low

The tool appears to retrieve news data, consistent with the server's stated purpose of providing market data access. No side effects, modifications, deletions, or financial transactions are implied. The empty description limits confidence slightly, but the context of other Read-only tools and the general nature of news retrieval as a data lookup function supports the Read classification.

From the tool's own definition: "Tool is named 'news' and belongs to a MetaTrader5 server that primarily provides market data retrieval and analysis functionality. Sibling tools (data_fetch_candles, data_fetch_ticks, correlation_matrix, etc.) are all Read operations."

## Use case

AI agents call news to retrieve information from MetaTrader5 MCP Server 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 MetaTrader5 MCP Server:

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