WHAT IT DOES

What youtube_video does on Crawlora

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

Parameter	Type	Required	Description
`id`	string	Yes	YouTube video ID (11-char code)

Parameters from the server's own tool schema.

RISK

Why youtube_video is rated Low

Even though youtube_video only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs youtube_video safely

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

youtube_video Allowed

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

View as policy code

policy.json

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

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

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