WHAT IT DOES

What get_streams does on Ncp

AI agents call get_streams to retrieve information from Ncp without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why get_streams is rated Low

This tool queries and retrieves information about live Twitch streams. It performs a read-only operation with no ability to modify data, execute code, delete resources, or trigger financial transactions. The blast radius of misuse is minimal—an agent could only retrieve stream information that is already publicly available.

From the tool's definition Tool name 'get_streams' and description 'Get live Twitch streams' indicate data retrieval with no modification or side effects.

RECOMMENDED RULE

The rule that runs get_streams safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Ncp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For get_streams, this is the rule to start with:

get_streams Allowed

get_streams is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_streams": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Ncp, apply this rule, and every get_streams call is checked against it from then on.
