## Facts

- Tool: `list_distribution_policies`
- Server: Mcpg (`pypi:mcpg`) — https://policylayer.com/tools/io-github-devopam-mcpg.md
- Install: `npx -y pypi:mcpg`
- Homepage: https://github.com/devopam/MCPg
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified

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

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

## Why list_distribution_policies is rated Low

The 'list_' prefix strongly indicates a read-only operation that retrieves or queries data about distribution policies. No side effects or modifications are implied. While the description is empty, the naming convention and context (PostgreSQL metadata introspection) support classification as Read with medium-high confidence.

From the tool's own definition: "Tool name 'list_distribution_policies' follows the 'list_*' pattern, which is a standard retrieval operation. The sibling tools show this server performs analytical and configuration functions on PostgreSQL."

## Use case

AI agents call list_distribution_policies to retrieve information from Mcpg 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 Mcpg:

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

## 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`
