reasonix-vision-mcp

Vision Bridge MCP Server — 让纯文本模型通过 MCP 调用视觉模型来"看到"图片。

支持任意 OpenAI 兼容的视觉 API(SiliconFlow / GPT-4o / Qwen-VL 等),含图片压缩功能。

⚠️ 注意: 本项目基于 SiliconFlow 平台在 Reasonix 中测试通过,其余平台/客户端未做完整测试,可能存在兼容性问题。

工具

工具 说明
describe_image 描述图片内容。支持本地图片路径或公网 URL
compress_image 压缩本地图片文件
v 版本信息(仅查看,不调用)

describe_image 参数

参数 必填 说明
image 图片路径:本地绝对路径或公网 URL
prompt 自定义描述指引,如"分析这个UI界面"
detail 视觉精度,默认 auto。传什么就用什么,直接透传给 API

compress_image 参数

参数 必填 默认值 说明
image 图片绝对路径
maxWidth 800 最大宽度(像素)。仅在不指定 maxSize 时生效
maxSize 目标大小,如 "1M""500KB""200K"

指定 maxSize 时,工具会二分逼近压缩到目标大小以内,绝不超出。
