These names and descriptions are the publisher's own, read from the source code. We print them as written. Our assessment is the findings above, not this list.

gemini_generate_image
gemini_edit_image
gemini_upload_image

Upload one or more images to the Gemini Files API and return their file URIs. Use this to pre-upload reference images before calling gemini_batch_submit. Uploaded files persist for 48 hours on Google's servers. Pass the returned URIs to batch_submit via the file_uris field to avoid slow base64 enco

gemini_batch_submit
gemini_batch_status

Check the status of a batch image generation job. Args: - batch_name (string, required): The batch ID to check (e.g. "batches/abc123"). Returns: - state: BATCH_STATE_PENDING, BATCH_STATE_RUNNING, BATCH_STATE_SUCCEEDED, BATCH_STATE_FAILED, etc. - output_file: The Gemini Files API reference fo

gemini_batch_results

Download and save images from a completed batch job. Checks the batch status, retrieves the output JSONL from Gemini, decodes each image, and saves them to the specified output directory using the key as the filename. Args: - batch_name (string, required): The batch ID (e.g. "batches/abc123").

// known CVEs in dependencies2 high

// full audit trail
The findings above are the summary. The full trail, every check we ran, each deduction, the network hosts observed and the dependency advisories, goes to verified publishers, along with an alert whenever a new one lands. Verified publishers can also review each finding and dispute it in one click. Publisher corrections have sharpened several of our checks this month, because the maintainer knows the codebase better than any scanner.
// improvement guidance — verified publishers only
We have 4 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
