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

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

## Why pip-list is rated Low

This is a read-only operation that queries the local Python environment to list installed packages. It has no side effects, cannot modify data, and does not execute arbitrary code or external operations. The blast radius of misuse is minimal—an attacker gains visibility into the Python environment but cannot install, remove, or execute packages.

From the tool's own definition: "Tool 'pip-list' runs pip list command which retrieves and returns a structured list of installed packages with no modification or execution of external operations."

## Use case

AI agents call pip-list to retrieve information from Http 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 Http:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "pip-list": {}
  }
}
```

## 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`
