## Facts

- Tool: `list_processes`
- Server: Procmon (`0xhackerfren/procmon-mcp`) — https://policylayer.com/tools/0xhackerfren-procmon-mcp.md
- Homepage: https://github.com/0xhackerfren/ProcMon-MCP
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

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

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

## Why list_processes is rated Low

This tool queries system state (running processes) but does not modify, execute, or delete anything. However, severity is elevated to 'medium' rather than 'low' because process enumeration combined with the server's access to kernel traces, event logs, and PE analysis could enable reconnaissance for privilege escalation or malware analysis when chained with other tools.

From the tool's own definition: "Tool name 'list_processes' and description 'List processes with optional name or PID filter' indicate a retrieval operation with no side effects. The verb 'list' is quintessentially a read operation."

## Use case

AI agents call list_processes to retrieve information from Procmon 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 Procmon:

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

## 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`
