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

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

## Why ssh_list_sessions is rated Low

This tool performs a passive enumeration of active sessions and available resources. It has no side effects, does not execute code, does not modify state, and does not delete or move money. The blast radius of misuse is minimal—an agent could only learn about what sessions exist, which is informational. Classified as Read with low severity.

From the tool's own definition: "Tool name 'ssh_list_sessions' and description 'List all active SSH sessions and remaining connection slots' indicate a read-only query operation that retrieves status information about existing sessions without modifying or executing anything."

## Use case

AI agents call ssh_list_sessions to retrieve information from SSH MCP Server 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 SSH MCP Server:

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

## 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`
