Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http spine-render https://lain42.top/studio/render/mcp-server/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Common questions

Is Spine Render safe?

It passed 0 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 16 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

lyco-ai-toolkit

多模态 AI 资源流水线：一条命令产出 Minecraft 皮肤、Bedrock 模型、BGM、立绘、歌词。

Owner: lilyco-42（云枢智创数码信息科技服务工作室）

调研与决策记录在 _RESEARCH/

现在能做什么

lyco-cli bundle --prompt 'a quiet librarian' --out out

skin.png 64x64 Minecraft 皮肤（合法，可校验）

model.geo.json Bedrock 几何（Blockbench 可导入）

lyrics.txt 分段歌词

manifest.json 每个产物的 backend 与 placeholder 标记

全部子命令

lyco-cli bundle    整包：skin + model + bgm + portrait + lyrics + manifest

接入 agent（MCP）

lyco-cli mcp 是一个 MCP server，用换行分隔的 JSON-RPC 2.0 收发。它把 12 个工具暴露给 lilyco_agent / Claude Code / Cursor：skin_template、skin_validate、 skin_quantize、model_humanoid、model_validate、glb_info、model_from_glb、 lyrics_generate、lyrics_validate、bgm_generate、portrait_generate、bundle。

手动试一次：

printf '%s\n' \

'{"jsonrpc":"2.0","id":1,"method":"initialize"}' \ '{"jsonrpc":"2.0","method":"notifications/initialized"}' \ '{"jsonrpc":"2.0","id":2,"method":"tools/list"}' \ | lyco-cli mcp

三个设计原则

解码大于编码。 音频、图像、歌词写完都要解回来核对；绝不把子进程退出码当作产出成功的证据。
placeholder 必须显眼。 内置 stub 后端在 CLI、manifest 的 placeholder 字段和 notes 里三处标注，一个 bundle 永远不会看起来像五次真实生成。
需要模型的藏在子进程后面。 不对 ACE-Step / ComfyUI / 任何 LLM 的 CLI 做假设，只约定参数形状，用 --backend 指过去。

生成：Kaggle 免费 GPU

皮肤生成真的能跑 —— 不需要本机有显卡：

lyco-cli skin generate --backend kaggle --owner <you> --slug lyco-skin-gen --seeds 7,42

它把 Rust 生成的笔记本推到 Kaggle，在免费的 Tesla T4 上跑 AliceKJ/BLOCKv0.6，轮询到结束，拉回产物，然后在本机做 overlay 修复、结构校验和人形预览。

分工是刻意的：Kaggle 只做它唯一不可替代的事（GPU 推理），UV 知识和修复逻辑归 Rust。 生成的笔记本里没有 UV 表，CI 会断言这一点。

其余需要模型的部分（音频引擎、图像引擎、LLM）仍是 --backend '<命令行>' 子进程边界。

F11 Spine：渲染，以及为什么它不随包发布

lyco-cli spine info model.atlas        # 页 / region / 是否声明 size、pma

lyco-cli spine normalize model.atlas # 从 PNG 头补/修 size，幂等 lyco-cli spine version model.skel # 读出需要的 Spine 版本

lyco-spine-render 能把 Spine 骨架摆姿势并在 CPU 上画成 PNG（describe / render --animation NAME）。已用真实方舟数据验证：Spine 3.8.99、52 mesh、508 三角形。

但它不随本仓库发布二进制，原因很具体：

它链接官方 Spine 运行时，那是 Spine Runtimes License Agreement（商业许可）
本仓库源码是 MIT，从它构建出的二进制不是 —— 发布需要你自己的 Spine 授权
所以默认 CI 只验证它能编译，不产出 artifact；windows-binary 只发纯 MIT 的 lyco-cli.exe

要拿到这个二进制，用仓库里的 build from source workflow（workflow_dispatch）：你在自己的 fork 里触发，在你自己的授权下构建，产物只进你这次 run。

它的输入：

target —— 默认 lyco-spine-render，也可选 lyco-cli 或 both
runner —— 默认 windows-latest，或 ubuntu-latest
`spine_lib` —— 要链接的 Spine 运行时 git 地址（默认 rusty_spine3.8）
`spine_rev` —— 该运行时的 revision，commit / tag / branch 都行

spine_lib 和 spine_rev 是真的生效的：workflow 会改写 crates/lyco-spine-render/Cargo.toml 里那一行再开始构建，所以你可以拿它试别的运行时。运行时地址、revision、许可链接会在构建开头打印，并且参与缓存 key，换 revision 不会误用旧产物。

缓存：默认 CI 和这个 workflow 都缓存两层 —— ~/.cargo/git/db 与 ~/.cargo/git/checkouts（Spine 运行时那个 git 依赖的 clone，冷启动最慢的一步），以及 rust-cache 管的 target/ 增量编译。

注意：`pma` 是 Spine 4.x 的键。 往 3.8 的 atlas 里写 pma: true 会让 3.8 运行时 完全读不了那个文件 —— 实测确认（方舟素材池 561 组里 243 组带着它）。两条路都通：

渲染时自动剥离：lyco-spine-render 读取前把 3.8 认不了的字段剥掉（旁路写一份临时 atlas，用完即删），561/561 全部可读可渲；
离线修复：lyco-cli spine normalize --strip-3-8 把剥离结果写回文件。

验证

每次 CI 跑：test → clippy -D warnings → build → 6 组冒烟测试 → fmt。冒烟测试用外部实现交叉验证：Python 的 wave 解码我们写的 WAV、直接读 PNG 头核对尺寸、现造 GLB 喂给转换、以及一次真实 MCP 会话。

已知缺口

真实 ACE-Step / ComfyUI / 混元 3D / LLM 接入需要 GPU 机器（皮肤走 Kaggle 已通）
keep-percent=12% 这个启发式对某些 seed 会整体清空残留很少的 overlay 矩形，可能丢掉真实衣物细节；需要人眼判断是否调低
BGM 目前是 WAV；mp3 转码需要 ffmpeg
转换出的模型贴图是「每盒平均色」，不是对原网格纹理的 UV 重映射
模型能否被 Blockbench 导入未经人工验证（自动化只能验到 schema 层）

术语更正

调研初稿曾写「YSM/BSM 是 BlockBench 格式」——错的，已在 _RESEARCH/02-niche-knowledge.md 第五节更正： Blockbench 没有这两个格式且是 GPL-3.0；YSM 是 Yes Steve Model 模组的加密二进制； BSM 不存在。本项目落点是开放的 Bedrock geometry。
