## Facts

- Tool: `render_image`
- Server: Blend Ai (`holdmybeer-gg/blend-ai`) — https://policylayer.com/tools/holdmybeer-gg-blend-ai.md
- Homepage: https://github.com/HoldMyBeer-gg/blend-ai
- Risk category: Execute (High risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Rate-limited

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

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

## Why render_image is rated High

Rendering an image in Blender triggers an external computational operation (invoking Blender's render engine), which consumes significant CPU/GPU resources and writes output files to disk. This qualifies as Execute due to triggering an external operation with effects depending on the current scene state. The description is empty, which lowers confidence.

From the tool's own definition: "Tool name 'render_image' on a Blender MCP server with 108 tools for 3D modeling, animation, and rendering."

## Use case

AI agents invoke render_image to trigger actions in Blend Ai. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Blend Ai:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "render_image": {
      "limits": [
        {
          "counter": "render_image_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}
```
