## Facts

- Tool: `env`
- Server: Test (`Dave-London/Pare`) — https://policylayer.com/tools/io-github-dave-london-pare-test.md
- Homepage: https://github.com/Dave-London/Pare
- 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": "env",
    "arguments": {}
  }
}
```

## Why env is rated Low

The tool retrieves system configuration data (Go environment variables) without creating, modifying, deleting, or executing anything. It has no side effects. While environment variables could theoretically contain sensitive information, the baseline capability is passive information retrieval.

From the tool's own definition: "Tool description states it 'Returns Go environment variables' and optionally allows requesting 'specific variables'. These are read-only operations that query environment state without modification."

## Use case

AI agents call env to retrieve information from Test 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 Test:

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

## 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`
