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

```json
{
  "jsonrpc": "2.0",

  "method": "tools/call",
  "params": {
    "name": "list_models",
    "arguments": {}

```

## Why list_models is rated Low

This tool retrieves information about available models without modifying, executing code, deleting data, or making financial transactions. It is a straightforward query operation that returns a static list. The severity is low because misuse would only expose model names and metadata, with no blast radius for unintended operations.

From the tool's own definition: "Tool name is 'list_models' and description states it 'List available DeepSeek models' with 'no parameters'. The verb 'List' and the stated purpose of querying available models for selection and validation are read-only operations with no side effects."

## Use case

AI agents call list_models to retrieve information from DeepSeek MCP Server 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 DeepSeek MCP Server:

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

## 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`
