WHAT IT DOES

What pt_upload_video does on Crow

AI agents use pt_upload_video to create or update resources in Crow — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Crow environment.

THE RISK

Medium Risk

Why pt_upload_video needs a policy

This tool creates and stores new video data in a project management system, modifying the state of the channel by adding persistent media content. This is a Write operation (reversible via deletion) rather than Destructive.

From the tool's definition Tool description explicitly states 'Upload a video file', which creates new media data. Parameters include 'file_path or file_base64+filename', confirming file creation/upload capability.

POLICY

How to control pt_upload_video

PolicyLayer is an MCP gateway — it sits between your AI agents and Crow, and nothing reaches the server without passing your rules. This is the rule we recommend for pt_upload_video:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "pt_upload_video": {
      "limits": [
        {
          "counter": "pt_upload_video_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

pt_upload_video stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

How do I enforce a policy on pt_upload_video? +

Register the Crow MCP server in PolicyLayer and add a rule for pt_upload_video: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Crow. Nothing to install.

What risk level is pt_upload_video? +

pt_upload_video is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit pt_upload_video? +

Yes. Add a rate_limit block to the pt_upload_video rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block pt_upload_video completely? +

Set action: deny in the PolicyLayer policy for pt_upload_video. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides pt_upload_video? +
