## Facts

- Tool: `ps`
- Server: Git (`Dave-London/Pare`) — https://policylayer.com/tools/io-github-dave-london-git.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": "ps",
    "arguments": {}
  }
}
```

## Why ps is rated Low

This tool performs a read-only operation analogous to 'docker ps', retrieving and presenting information about running containers. It has no side effects, creates no modifications, executes no code, and causes no data loss. The only risk is information disclosure of container infrastructure details, which is a low-severity concern in a controlled environment.

From the tool's own definition: "Tool name 'ps' and description 'Lists Docker containers with structured status, ports, and state information' indicate a query operation that retrieves container metadata without modification."

## Use case

AI agents call ps to retrieve information from Git 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 Git:

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

## 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`
