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

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "cern-search-records",
    "arguments": {}
  }
}
```

## Why cern-search-records is rated Low

This tool retrieves and queries publicly available data from CERN's open data repository. It has no side effects, cannot modify or delete data, and does not execute code or trigger external operations. It is a straightforward read-only search interface. The low severity reflects that misuse would only expose publicly available scientific data, with no blast radius.

From the tool's own definition: "Tool name includes 'search' and description states it 'Search[es] the CERN Open Data Portal for datasets, software, and documentation' — a pure query operation with no modification, deletion, or execution capability."

## Use case

AI agents call cern-search-records to retrieve information from Meta Data Mcp 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 Meta Data Mcp:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
