README

Visual Generator MCP

外部多模态生成 MCP Server（图片 + 视频），用于在 Tailscale 内网被 MCP Host（例如 eCommerceAgent）接入并调用。

目标

只负责生成与交付：调用方负责业务语义，本服务负责模型调用与 OSS/CDN URL 返回。
工具稳定：imageGenerate、videoGenerate、materialWrite 三块。
模式统一：imageGenerate/videoGenerate 通过 generationMode 区分常规与智能模式。

工具（MCP Tools）

1) `imageGenerate`（Host 落位点：`visual__imageGenerate`）

必填：vendor、modelName、prompt、storageMode/env/project/referenceType/referenceId
新增：generationMode（normal|smart，默认 normal）
当前状态：
- generationMode=normal 已支持
- generationMode=smart 首期预留（未开放）
出参：structuredContent.images[]（imageUrl/mimeType/objectKey）

2) `videoGenerate`（Host 落位点：`visual__videoGenerate`）

常规必填：vendor、modelName、storageMode/env/project/referenceType/referenceId
模式字段：generationMode（normal|smart，默认 normal）
模式说明：
- normal：调用方提供完整 prompt 与参数
- smart：先做需求分析与方案生成，再做素材匹配与分段生成（视频优先实施）
出参：structuredContent.videos[]（videoUrl/mimeType/objectKey）

3) `materialWrite`（Host 落位点：`visual__materialWrite`）

定位：将用户认可素材写入素材库，并自动打标签与权限字段。
当前状态：规划中（详见 docs/plan/plan-intelligent-generation.md）。

兼容说明（历史调用）：

旧工具名 generate / generateVideo 已废弃，调用方需升级到 imageGenerate / videoGenerate。
