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

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

## Why extract_credentials is rated Low

This is a Read operation because it retrieves/queries sensitive data (credentials) from PCAP files with no side effects or modifications to the data or system. However, severity is high rather than low because: (1) the blast radius of exposing extracted credentials to an AI agent is substantial—an agent could use them for unauthorized access, lateral movement, or credential theft; (2) credentials are inherently…

From the tool's own definition: "The tool 'extract_credentials' from network traffic analysis (PCAP files) is described as extracting potential credentials for analysis. The verb 'extract' and the passive framing 'for LLM analysis' indicate data retrieval without modification."

## Use case

AI agents call extract_credentials to retrieve information from WireMCP 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 WireMCP:

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

## 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`
