## Facts

- Tool: `list_tools`
- Server: Uefn (`quangdang46/uefn-verse-mcp`) — https://policylayer.com/tools/quangdang46-uefn-verse-mcp.md
- Homepage: https://github.com/quangdang46/uefn-verse-mcp
- 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": "list_tools",
    "arguments": {}
  }
}
```

## Why list_tools is rated Low

This is a read-only operation that enumerates registered tools. It has no side effects, does not create, modify, or delete data, and does not execute external operations. The blast radius of misuse is minimal—an AI agent learning which tools exist poses negligible risk.

From the tool's own definition: "Tool name 'list_tools' and description 'List all registered uefn_tools tools' indicate a query operation that retrieves information about available tools without modifying state."

## Use case

AI agents call list_tools to retrieve information from Uefn 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 Uefn:

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

## 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`
