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

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

## Why europepmc-search is rated Low

This tool queries a public biomedical literature database (Europe PMC) and returns results. It has no side effects, does not modify data, does not execute code or commands, and does not delete or move resources. It is purely informational retrieval, fitting the Read category. Severity is low as misuse would at worst result in excessive API calls or information access, with no destructive potential.

From the tool's own definition: "Tool name 'europepmc-search' and description 'Search Europe PMC biomedical literature with cursor-based pagination' indicate a retrieval-only operation."

## Use case

AI agents call europepmc-search 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": {
    "europepmc-search": {}
  }
}
```
