## Why search is rated Low

This tool queries multiple data sources and retrieves search results. It performs no data modifications, deletions, financial transactions, or code execution. The low severity reflects that misuse causes only information exposure, not system compromise or destructive outcomes.

From the tool's own definition: "Tool named 'search' on a server described as 'Controllable multi-source search MCP server' that searches Reddit, X, YouTube, HN, GitHub, arXiv, Polymarket, and other sources."

## Use case

AI agents call search to retrieve information from 999md 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 999md:

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