glm4v-vision-mcp
This server provides AI-powered image analysis via the GLM-4V Flash model, supporting three main functions:
Analyze Image (
analyze_image): Send an image and a custom prompt to get natural language analysis, such as describing scenes, identifying objects, or answering questions. Supports PNG, JPG, JPEG, WebP, and GIF formats.Extract Text (
extract_text): Perform OCR to extract text from images, with language detection for Chinese, English, or automatic mode.Describe Image (
describe_image): Generate structured image descriptions in multiple styles — detailed, concise, poetic, or technical — ideal for accessibility and annotation.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@glm4v-vision-mcp Extract the text from the image at ./screenshot.png"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.

Scored across 3 tools
describe_image and analyze_image have overlapping purposes—both generate descriptions of image content, making it unclear which to use. extract_text is distinct, but the boundary between the other two is ambiguous.
All tool names follow a consistent verb_noun pattern (describe_image, analyze_image, extract_text) using snake_case. No stylistic deviations.
With 3 tools, the server is well-scoped for a vision-focused MCP. Each tool addresses a core image understanding task without unnecessary bloat.
The toolset covers basic image description, analysis, and OCR, which are the primary vision tasks. Minor gaps exist (e.g., no image comparison or specific object detection), but the core surface is complete.
