## Facts

- Tool: `get_user_id`
- Server: Cryptosense (`josephibra/cryptosense-mcp`) — https://policylayer.com/tools/josephibra-cryptosense-mcp.md
- Homepage: https://github.com/josephibra/cryptosense-mcp
- Risk category: Read (Low risk)

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

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

## Why get_user_id is rated Low

The tool appears to retrieve or query user identity information with no apparent side effects. While the empty description reduces confidence slightly, the naming convention strongly suggests a Read operation. Even if this retrieves user context for subsequent operations, retrieval itself is non-destructive and fits the Read category.

From the tool's own definition: "Tool name 'get_user_id' indicates retrieval of a user identifier. No description provided to suggest write, delete, execute, or financial operations."

## Use case

AI agents call get_user_id to retrieve information from Cryptosense 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 Cryptosense:

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