WHAT IT DOES

What news does on MetaTrader5 MCP Server

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.

RISK

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 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.

RECOMMENDED RULE

The rule that runs news safely

PolicyLayer is an MCP gateway: it sits between your AI agents and MetaTrader5 MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For news, this is the rule to start with:

news Allowed

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

View as policy code

policy.json

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

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

The button opens the PolicyLayer dashboard: create your workspace, connect MetaTrader5 MCP Server, apply this rule, and every news call is checked against it from then on.
