// key findings

✅

No credential exfiltration, no sensitive file access, no obfuscation

Static analysis found nothing flowing your secrets to unexpected places.

🔐

You'll be asked for 4 credentials: ANTHROPIC_API_KEY, GEMINI_API_KEY, OPENAI_API_KEY, VISIONTOOL_API_KEY

These are read from process.env at runtime. Make sure you trust where they’ll be sent.

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.

describe_image

【默认仅限 GLM/DeepSeek 系列模型调用】Describe an image for a text-only agent. Accepts a local path, base64 image data, or URL.

ocr_image

【默认仅限 GLM/DeepSeek 系列模型调用】Extract visible text from an image with optional language and layout hints.

answer_about_image

【默认仅限 GLM/DeepSeek 系列模型调用】Answer a specific question using visual evidence from one image.

compare_images

【默认仅限 GLM/DeepSeek 系列模型调用】Compare two images and summarize relevant differences for a text-only agent.

// environment variables

To run this server yourself, you supply these values. They go in your own MCP client configuration and stay on your machine. The secret label means the value is sensitive, not that the server mishandles it.

// quality suggestions

All four hints declared on every tool

4/4 tools missing one or more hints — describe_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); ocr_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint); answer_about_image (missing: readOnlyHint, destructiveHint, idempotentHint, openWorldHint), +1 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.

For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.

// 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 2 concrete improvements we can share with the publisher of this MCP. Each comes with specific guidance to raise the trust score.
