Evolink Image — AI Image Generation (GPT Image, Nano Banana 2, Seedream, GPT-4o)

Security checks across malware telemetry and agentic risk

Overview

This skill is a disclosed EvoLink image-generation integration; it sends prompts and images to EvoLink and uses temporary public file URLs as part of its stated purpose.

Install only if you trust EvoLink with your prompts, source images, generated images, and API-key-backed usage. Avoid uploading confidential or personal images unless you are comfortable with temporary public URLs, and consider pinning the MCP package version instead of using @latest.

Missing User Warnings

Medium
Confidence
94% confidence
Finding
The document explicitly instructs users to upload images to a file hosting service and then use the returned `file_url` as a publicly accessible link, but it does not prominently warn that uploaded content becomes public and expires after 72 hours. This can lead users to unintentionally expose sensitive images, metadata, or proprietary content to anyone with the URL, especially in an agent context where uploads may be automated.

External Transmission

## Upload a Local File

```bash
curl -X POST https://files-api.evolink.ai/api/v1/files/upload/stream \
  -H "Authorization: Bearer $EVOLINK_API_KEY" \
  -F "file=@/path/to/image.jpg"
```
Confidence
88% confidence
Finding
This documentation directs an agent or user to transmit local files and remote URLs to an external service controlled by Evolink. While external upload is expected for a file-hosting API, it is still a real data-exposure risk because local images may contain sensitive visual content or embedded EXIF metadata, and the resulting hosted file is intended to be publicly accessible.
