## Why subscribeDcp is rated Low

Subscribing to DCP (likely a market data stream) is a Read operation that retrieves real-time information with no side effects. While authentication is required, the tool does not execute trades, modify positions, transfer funds, or delete data. The blast radius of accidental misuse is low—an agent subscribing to unwanted data streams causes no financial or operational harm.

From the tool's own definition: "Tool name 'subscribeDcp' indicates subscription to data streams; description translates to 'Subscribe to DCP changes (requires authentication)' — suggests real-time data subscription rather than action execution."

## Use case

AI agents call subscribeDcp to retrieve information from Bybit 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 Bybit MCP Server:

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