UI Design to Code MCP

中文 | English

MCP server for Codex, Cursor, and Claude Code that turns UI screenshots, source images, Figma MCP node JSON, and Figma-plus-screenshot hybrid input into traceable design-to-code artifacts.

npx -y ui-design-to-code-mcp@latest install --client codex

Use it when you need more than a one-shot screenshot-to-code prompt:

Decode UI screenshots and Figma data into source manifests, reference analysis, Vision IR, Node Compression IR, and Semantic UI node trees.
Preserve traceability from generated code plans back to visual primitives, grouped candidates, and source pixels.
Generate adapter-ready artifacts for Web, iOS, Android, and other UI implementation targets.
Run audit gates for text overflow, media coverage, navigation structure, visual review evidence, and cleanup.

中文

ui-design-to-code-mcp 是一个用于 UI design-to-code 流程的 MCP server。它可以把 UI 截图、Figma MCP 节点 JSON，或 Figma 节点 + 截图的混合输入，接入一套结构化、可追踪、可校验的产物流水线。

它不替代真正写代码的 agent/model。它的职责是标准化运行目录、输入清单、Figma 数据集、中间 IR 合约、目标平台布局产物、代码生成记录、精确切图产物、视觉验收门禁、产物校验和清理流程。

核心亮点

支持 Codex、Cursor、Claude Code。
创建隔离的标准运行目录：generated/ui-design-to-code/<run-id> 或 /private/tmp/ui-design-to-code/<run-id>。
统一接入截图、图片、Figma 节点 JSON、Figma + 截图混合输入。
覆盖完整流程：decode、planning、target IR、codegen、自动视觉验收、runtime review、validate、cleanup。
提供 Semantic UI IR、Cross-platform Node Data、Target Layout IR、视觉验收、产物生命周期等 schema 合约。
支持基于 source_bbox 的源图精确 bitmap/icon 切图。
Codex 安装后使用本地稳定 serve 命令，避免每次 MCP 启动都执行 npx @latest。

快速开始

安装到 Codex

npx -y ui-design-to-code-mcp@latest install --client codex

配置 Figma token：

ui-design-to-code-mcp setup-figma-token

该命令会提示粘贴 token，并写入 ~/.codex/config.toml 的 [mcp_servers.ui_design_to_code.env]。如果要在脚本里使用：

printf %s '<YOUR_FIGMA_TOKEN>' | ui-design-to-code-mcp configure-figma-token --client codex --stdin

安装到 Cursor 项目级配置

npx -y ui-design-to-code-mcp@latest install \
  --client cursor \
  --scope project \
  --project-dir .

配置 Figma token：

ui-design-to-code-mcp configure-figma-token --client cursor --scope project --project-dir . --token <YOUR_FIGMA_TOKEN>

一次安装到所有支持的本地客户端

npx -y ui-design-to-code-mcp@latest install \
  --clients cursor,claude-code,codex \
  --scope project \
  --project-dir .

检查或直接启动服务

npx -y ui-design-to-code-mcp@latest doctor
npx -y ui-design-to-code-mcp@latest serve

执行模式

模式	是否需要 target	主要用途
`decode-only`	否	只采集源输入、vision/compression/semantic 产物，不生成平台计划或代码。
`plan-only`	否	生成跨平台节点数据和转换计划，不生成目标布局或代码。
`target-ir`	是	登记目标平台布局 IR，不修改代码。
`codegen`	是	生成或修改实现代码，并记录常规验证结果。
`codegen-with-auto-review`	是	记录代码生成、视觉验收依据，并执行相似度门禁。
`runtime-review`	是	对已有运行时实现进行截图验收，不修改代码。

目标平台示例：

ios-uikit / ios-swiftui / web-react / web-next / android-compose / android-view

输入源选择

输入类型	适用场景	推荐工具
截图或图片	设计源是渲染后的图像。	`ingest_image_source`
Figma 节点 JSON 或 Figma REST 直连	需要结构、命名、文本、组件、样式和布局元数据。	`ingest_figma_source`
Figma 节点 + 截图 / REST 导出截图	同时需要结构化信息和像素级视觉基准。	`ingest_figma_source`

能同时拿到 Figma 节点和截图时，优先使用混合输入：Figma 节点提供结构化信息，截图提供像素级视觉基准，便于后续视觉复核。

产物运行目录

所有流程都从 create_design_run 开始。它会创建独立 runRoot 和 artifact-run-manifest.json。

项目内默认目录：

generated/ui-design-to-code/<timestamp>-<slug>/
  artifact-run-manifest.json
  source/
  figma/
  analysis/
  vision/
  compression/
  semantic/
  cross-platform/
  targets/
  assets/
  qa/
  review/

临时运行目录：

/private/tmp/ui-design-to-code/<timestamp>-<slug>/

客户端安装

Codex

Codex 安装器会写入用户级 MCP 配置，并让运行时启动路径脱离网络依赖。

Codex plugin marketplace 安装：

codex plugin marketplace add Kinglions/ui-design-to-code-mcp --ref main
codex plugin list --marketplace ui-design-to-code
codex plugin add ui-design-to-code@ui-design-to-code

安装后检查 MCP server：

codex mcp list

该插件会把 ui_design_to_code 注册为：

npx -y ui-design-to-code-mcp@latest serve

仍然可以使用 npm 方式直接安装 MCP：

npx -y ui-design-to-code-mcp@latest install --client codex

安装包路径：

~/.codex/mcp-packages/ui-design-to-code-mcp

Codex serve 命令：

~/.codex/bin/serve-ui-design-to-code-mcp

macOS 每日更新任务：

~/Library/LaunchAgents/com.wuyb.codex.update-mcp-packages.plist

更新命令：

~/.codex/bin/update-mcp-packages

当安装规格是 ui-design-to-code-mcp@latest 时，更新脚本每天 04:15 检查一次 npm latest，只有版本变化时才下载更新。更新后的包会在 Codex 下一次启动或重新加载该 MCP server 时生效。

Codex 配置示例：

[mcp_servers.ui_design_to_code]
command = "/Users/<user>/.codex/bin/serve-ui-design-to-code-mcp"
args = []
startup_timeout_sec = 30

卸载：

npx -y ui-design-to-code-mcp@latest uninstall --client codex

Cursor

项目级配置：

{
  "mcpServers": {
    "ui-design-to-code": {
      "command": "npx",
      "args": ["-y", "ui-design-to-code-mcp@latest", "serve"]
    }
  }
}

安装：

npx -y ui-design-to-code-mcp@latest install \
  --client cursor \
  --scope project \
  --project-dir .

卸载：

npx -y ui-design-to-code-mcp@latest uninstall \
  --client cursor \
  --scope project \
  --project-dir .

Claude Code

项目级安装：

npx -y ui-design-to-code-mcp@latest install \
  --client claude-code \
  --scope project \
  --project-dir .

用户级安装：

claude mcp add-json ui-design-to-code \
  '{"type":"stdio","command":"npx","args":["-y","ui-design-to-code-mcp@latest","serve"]}' \
  --scope user

工具参考

`get_run_modes`

返回支持的执行模式、目标平台、触发示例和模式选择提示。

当用户提供 UI 截图、参考图、Figma 设计或 design-to-code 任务，但没有明确指定模式时，应先调用它。

典型输入：

{ "requestText": "convert this screenshot to web code" }

`create_design_run`

创建运行目录和 artifact-run-manifest.json。

关键入参：

workspace：生成目录所在项目根目录。
slug：可读的 run 名称后缀。
mode：执行模式。
targets：target/codegen/review 模式必填。
useTmp：为 true 时写入 /private/tmp。

runRoot
manifestPath
mode

`ingest_image_source`

把截图或图片登记为源输入。

输出：

source/design-source-manifest.json
source/page.source-manifest.json

关键入参：

runRoot
imagePath
sourceId
无法自动读取尺寸时传 widthPx、heightPx
knownViewport
logicalUnit

`ingest_figma_source`

登记 Figma 输入源。支持：

传入现成 Figma 节点 JSON。
提供 Figma URL / figma.fileKey / figma.nodeId，并通过 apiToken 或环境变量（默认尝试 FIGMA_API_TOKEN、FIGMA_ACCESS_TOKEN、FIGMA_OAUTH_TOKEN）让 MCP 直接调用 Figma REST API。
在 1 或 2 的基础上附带截图，或让 MCP 自动导出截图和 target-aware 资产。
如果同时提供 projectRoot，MCP 会在下载完成后把资产自动同步到目标工程的默认资源目录，同时保留 runRoot 中的归档副本。

输出：

source/design-source-manifest.json
figma/figma-source-dataset.json
figma/figma-node-index.json
figma/figma-asset-plan.json
figma/raw-node-response.json
figma/raw-file-metadata.json
figma/raw-image-fills.json
figma/figma-asset-downloads.json
targets/asset-sync-manifest.json

关键入参：

runRoot
figmaUrl
figma.fileKey
figma.nodeId
nodeJson 或 nodeJsonPath
screenshotPath
figmaBounds
fetchFromApi
apiToken / tokenEnvVar
downloadScreenshot
downloadAssets
screenshotScale
projectRoot

资源同步规则：

web-react / web-next：默认同步到 public/ui-design-to-code/figma/...；若无 public/，回退到 src/assets/ui-design-to-code/figma/...
ios-uikit / ios-swiftui：优先同步到首个发现的 .xcassets，自动创建 .imageset
android-compose / android-view：默认同步到 app/src/main/res/drawable；若无则搜索 src/main/res

也可以显式单独调用：

sync_target_assets

如果缺少 token，MCP 会要求用户直接输入 Figma token，并通过 configure_figma_token 自动写入全局 Codex 配置；只有自动配置不可用时，才使用备用命令：

ui-design-to-code-mcp setup-figma-token

`slice_image_assets`

根据 layers.manifest.json 中的 source_bbox，从源图精确裁切 bitmap/icon 资源。

这是显式调用的独立工具，不会改变 decode、plan、target IR 或 codegen 的默认流程。

输入 manifest 示例：

[
  {
    "id": "icon-tab-home",
    "type": "bitmap",
    "source_bbox": { "x": 120, "y": 980, "width": 72, "height": 72 },
    "asset": "icon-tab-home.png",
    "transparent_required": true,
    "z_index": 20
  }
]

典型 tool 入参：

{
  "runRoot": "/path/to/run",
  "sourcePath": "/path/to/source.png",
  "layersManifestPath": "/path/to/layers.manifest.json",
  "canvasWidth": 750,
  "onlyType": "bitmap"
}

默认输出：

assets/slices/<asset>.png
assets/slices/layers.manifest.normalized.json
qa/bbox-preview.svg
qa/png-asset-audit.json

切图脚本使用源图像素坐标，不自动 trim，不改变输出画布尺寸。它会保留源像素和源 alpha。当前版本不引入额外图像依赖，因此不做背景抠除；当无法读取 alpha 细节时，审计报告会把透明/贴边检查标记为不可用。

`build_reference_analysis`

登记模型生成的 Reference Image Analysis。它位于 Vision IR 之前，用来记录原始像素尺寸、根画板、语义顶层分组、文本/媒体/图标/材质清单、底部导航、严格提取设置、高风险区域和后续审计计划。

如果没有传 artifactPath，工具会返回需要生成该产物的 schema 和参考说明。

默认 artifact type：

reference_analysis

`build_semantic_ir`

登记 model 生成的 Platform-neutral Semantic UI IR。

如果没有传 artifactPath，工具会返回需要生成该产物的 schema 和参考说明。

默认 artifact type：

platform_neutral_semantic_ui_ir

`build_cross_platform_nodes`

登记 Cross-platform Node Data。

如果没有传 artifactPath，工具会返回对应 schema 合约。

默认 artifact type：

cross_platform_node_data

`build_target_ir`

登记目标平台布局 IR。

schema 提示按 target 名称选择：

Android target 使用 Android layout schema。
iOS target 使用 iOS SwiftUI layout schema。
其他 target 使用 Web React layout schema。

`run_codegen`

记录实现代码变更和常规验证结果，不执行视觉验收门禁。

输出：

review/codegen-result.json

`run_codegen_with_auto_review`

记录代码生成结果和视觉验收依据。

当提供 visualReviewResultPath 时，只有满足下面条件才标记为可交付：

review.status == "passed"
minimum non-material similarity >= 0.9

输出：

review/codegen-with-auto-review-result.json

`validate_pipeline`

校验现有 run 的跨产物链路。它会检查必需产物是否存在，以及 vision、compression、semantic、cross-platform、target planning 之间的 traceability 是否一致。

`audit_image_decoding`

审计截图/图片解析产物。它会检查 reference analysis 是否匹配源图尺寸、顶层分组是否越界、审计章节是否齐全、文本是否有字体度量、媒体/图标区域是否被纳入、semantic node 是否保留 traceability、单行文本是否存在换行风险、底部导航是否包含槽位，以及低置信节点是否提供 alternatives。

默认输出：

qa/image-decoding-audit.json

`cleanup_design_run`

运行产物清理，默认 dry-run。

典型入参：

{ "runRoot": "/path/to/run", "apply": false }

只有确认要删除可清理产物时，才设置 apply: true。

常见工作流

截图转 Web 代码

用户未指定模式时，调用 get_run_modes。
调用 create_design_run，选择 mode: "codegen" 或 mode: "codegen-with-auto-review"，并设置 targets: ["web-react"]。

English

ui-design-to-code-mcp is an MCP server that standardizes the artifact pipeline for converting UI screenshots, Figma MCP node JSON, or Figma-plus-screenshot hybrid sources into implementation-ready design-to-code outputs.

It does not replace the coding agent or model. Instead, it gives agents a reliable workflow for run directories, source manifests, Figma datasets, intermediate IR contracts, target layout artifacts, codegen records, asset slicing outputs, visual review gates, validation, and cleanup.

Highlights

Works with Codex, Cursor, and Claude Code.
Creates isolated artifact runs under generated/ui-design-to-code/<run-id> or /private/tmp/ui-design-to-code/<run-id>.
Supports screenshots, source images, Figma node JSON, and hybrid Figma + screenshot input.
Covers the full pipeline: decode, planning, target IR, codegen, auto review, runtime review, validation, and cleanup.
Provides schema-backed contracts for Semantic UI IR, Cross-platform Node Data, Target Layout IR, visual review, and artifact lifecycle.
Supports precise source-image asset slicing using explicit source_bbox layer manifests.
Optimizes Codex startup by installing a stable local MCP serve command instead of running npx @latest on every startup.

Quick Start

Install for Codex

npx -y ui-design-to-code-mcp@latest install --client codex

Install for Cursor project config

npx -y ui-design-to-code-mcp@latest install \
  --client cursor \
  --scope project \
  --project-dir .

Install for all supported local clients

npx -y ui-design-to-code-mcp@latest install \
  --clients cursor,claude-code,codex \
  --scope project \
  --project-dir .

Check or run the server

npx -y ui-design-to-code-mcp@latest doctor
npx -y ui-design-to-code-mcp@latest serve

Recommended Workflow

Choose a mode with get_run_modes when the user has not specified one.
Create an artifact run with create_design_run.
Register source input with ingest_image_source or ingest_figma_source.
For screenshot/image input, produce and register Reference Image Analysis with build_reference_analysis.
Generate and register Semantic UI IR, Cross-platform Node Data, and Target Layout IR.
Audit image decoding quality with audit_image_decoding when Vision/Compression/Semantic artifacts exist.
Generate or modify code in the host project.
Record results with run_codegen or run_codegen_with_auto_review.
Validate the full artifact chain with validate_pipeline.
Optionally clean generated artifacts with cleanup_design_run.

Execution Modes

Mode	Target required	Main use
`decode-only`	No	Capture source manifests, vision/compression/semantic artifacts. No target plan or code.
`plan-only`	No	Add cross-platform node data and conversion planning. No target layout or code.
`target-ir`	Yes	Register target-platform layout IR. No code changes.
`codegen`	Yes	Generate or modify implementation code and record validation.
`codegen-with-auto-review`	Yes	Record codegen plus visual review evidence and similarity gate.
`runtime-review`	Yes	Review an existing runtime implementation against the source. No code changes.

Target platform examples:

ios-uikit / ios-swiftui / web-react / web-next / android-compose / android-view

Source Input Strategy

Source type	Use when	Recommended tool
Screenshot or image	The design source is a rendered image.	`ingest_image_source`
Figma MCP node JSON	You need structure, names, text, components, styles, and layout metadata.	`ingest_figma_source`
Figma node JSON + screenshot	You need both structural metadata and pixel-level visual truth.	`ingest_figma_source`

Hybrid Figma input is preferred when available because Figma nodes provide structure while screenshots provide the pixel baseline for visual review.

Artifact Run Layout

Every workflow starts with create_design_run, which creates a dedicated runRoot and an artifact-run-manifest.json.

Project run layout:

generated/ui-design-to-code/<timestamp>-<slug>/
  artifact-run-manifest.json
  source/
  figma/
  analysis/
  vision/
  compression/
  semantic/
  cross-platform/
  targets/
  assets/
  qa/
  review/

Temporary runs use:

/private/tmp/ui-design-to-code/<timestamp>-<slug>/

Client Installation

Codex

The Codex installer writes a user-level MCP config and keeps runtime startup off the network path.

Codex plugin marketplace install:

codex plugin marketplace add Kinglions/ui-design-to-code-mcp --ref main
codex plugin list --marketplace ui-design-to-code
codex plugin add ui-design-to-code@ui-design-to-code

After installation, verify the MCP server:

codex mcp list

The plugin registers ui_design_to_code with:

npx -y ui-design-to-code-mcp@latest serve

Direct npm-based MCP install remains available:

npx -y ui-design-to-code-mcp@latest install --client codex

Installed package:

~/.codex/mcp-packages/ui-design-to-code-mcp

Codex serve command:

~/.codex/bin/serve-ui-design-to-code-mcp

Daily updater on macOS:

~/Library/LaunchAgents/com.wuyb.codex.update-mcp-packages.plist

Updater command:

~/.codex/bin/update-mcp-packages

When the install spec is ui-design-to-code-mcp@latest, the updater checks npm once per day at 04:15 and downloads a new version only when npm latest changes. The updated package is used the next time Codex starts or reloads this MCP server.

Codex config example:

[mcp_servers.ui_design_to_code]
command = "/Users/<user>/.codex/bin/serve-ui-design-to-code-mcp"
args = []
startup_timeout_sec = 30

Uninstall:

npx -y ui-design-to-code-mcp@latest uninstall --client codex

Cursor

Project config:

{
  "mcpServers": {
    "ui-design-to-code": {
      "command": "npx",
      "args": ["-y", "ui-design-to-code-mcp@latest", "serve"]
    }
  }
}

Install:

npx -y ui-design-to-code-mcp@latest install \
  --client cursor \
  --scope project \
  --project-dir .

  '{"type":"stdio","command":"npx","args":["-y","ui-design-to-code-mcp@latest","serve"]}' \
  --scope user

Tool Reference

`get_run_modes`

Returns supported modes, target platforms, trigger examples, and the mode-selection prompt.

Use it when the user provides a UI screenshot, reference image, Figma design, or design-to-code request without naming a mode.

Typical input:

{ "requestText": "convert this screenshot to web code" }

`create_design_run`

Creates the run directory and artifact-run-manifest.json.

Key inputs:

workspace: project root for generated outputs.
slug: readable run suffix.
mode: one supported execution mode.
targets: required for target/codegen/review modes.
useTmp: writes under /private/tmp when true.

Returns:

runRoot
manifestPath
mode

`ingest_image_source`

Registers a screenshot or image into:

source/design-source-manifest.json
source/page.source-manifest.json

Key inputs:

runRoot
imagePath
sourceId
widthPx and heightPx when size cannot be inferred
knownViewport
logicalUnit

`ingest_figma_source`

Registers Figma MCP node JSON, an optional screenshot, or both.

Outputs:

source/design-source-manifest.json
figma/figma-source-dataset.json

Key inputs:

runRoot
figma.fileKey
figma.nodeId
nodeJson or nodeJsonPath
screenshotPath
figmaBounds

`slice_image_assets`

Crops bitmap/icon assets from a source image using a layers.manifest.json with source_bbox entries.

This tool is opt-in and does not alter decode, planning, target IR, or codegen flows.

Layer manifest example:

[
  {
    "id": "icon-tab-home",
    "type": "bitmap",
    "source_bbox": { "x": 120, "y": 980, "width": 72, "height": 72 },
    "asset": "icon-tab-home.png",
    "transparent_required": true,
    "z_index": 20
  }
]

Typical tool input:

{
  "runRoot": "/path/to/run",
  "sourcePath": "/path/to/source.png",
  "layersManifestPath": "/path/to/layers.manifest.json",
  "canvasWidth": 750,
  "onlyType": "bitmap"
}

Default outputs:

assets/slices/<asset>.png
assets/slices/layers.manifest.normalized.json
qa/bbox-preview.svg
qa/png-asset-audit.json

The slicer uses exact source pixel bboxes and never auto-trims output canvases. It preserves source pixels and source alpha. Background removal is not performed without an external alpha-capable image decoder, so the audit report marks alpha-specific checks as unavailable when it cannot inspect them.

`build_reference_analysis`

Registers model-generated Reference Image Analysis before Vision IR. This captures the original pixel size, root frame, semantic top-level groups, text/media/icon/material inventory, bottom navigation, strict extraction settings, high-risk zones, and the audit plan used for later decoding.

When artifactPath is missing, the tool returns the schema and reference path.

Default artifact type:

reference_analysis

`build_semantic_ir`

Registers model-generated Platform-neutral Semantic UI IR.

When artifactPath is missing, the tool returns the schema and reference path.

Default artifact type:

platform_neutral_semantic_ui_ir

`build_cross_platform_nodes`

Registers Cross-platform Node Data.

When artifactPath is missing, the tool returns the required schema contract.

Default artifact type:

cross_platform_node_data

`build_target_ir`

Registers target-platform layout IR for a selected target.

Schema hint selection:

Android targets use Android layout schemas.
iOS targets use iOS SwiftUI layout schemas.
Other targets use Web React layout schemas.

`run_codegen`

Records implementation output and validation summary without enforcing visual review.

Output:

review/codegen-result.json

`run_codegen_with_auto_review`

Records implementation output plus visual review evidence.

When visualReviewResultPath is provided, delivery is ready only when:

review.status == "passed"
minimum non-material similarity >= 0.9

Output:

review/codegen-with-auto-review-result.json

`validate_pipeline`

Validates an existing run by checking required artifacts and traceability links between vision, compression, semantic, cross-platform, and target planning artifacts.

`audit_image_decoding`

Audits screenshot/image decoding artifacts. It checks that reference analysis matches source dimensions, top-level groups stay in bounds, audit sections are present, text runs carry font metrics, media/icon regions are accounted for, semantic nodes keep traceability, single-line text avoids wrap risk, bottom navigation exposes slots, and uncertain nodes provide alternatives.

Default output:

`cleanup_design_run`

Runs artifact cleanup in dry-run mode by default.

Use:

{ "runRoot": "/path/to/run", "apply": false }

Set apply: true only when cleanup should actually remove eligible artifacts.

Common Workflows

Screenshot to Web Code

Call get_run_modes if the user has not chosen a mode.
Call create_design_run with mode: "codegen" or mode: "codegen-with-auto-review" and targets: ["web-react"].
Call ingest_image_source with the source screenshot.
Call build_reference_analysis after analyzing the screenshot structure.
Generate or register Semantic UI IR, Cross-platform Node Data, and Target Layout IR.
Call audit_image_decoding after Vision/Compression/Semantic artifacts are available.
Implement code in the host project.
Call run_codegen or run_codegen_with_auto_review.
Call validate_pipeline.

Figma Hybrid to Target IR

Fetch Figma node JSON through Figma MCP.
Capture or provide the matching Figma frame screenshot.
Call create_design_run with mode: "target-ir" and the target platform.
Call ingest_figma_source with nodeJson and screenshotPath.
Generate target layout IR.
Call build_target_ir.
Call validate_pipeline.

Precise Screenshot Asset Slicing

Call create_design_run.
Call ingest_image_source.
Create a layers.manifest.json with source pixel bboxes for bitmap/icon layers.
Call slice_image_assets.
Use assets/slices/ in generated code.
Review qa/bbox-preview.svg and qa/png-asset-audit.json.

Update and Versioning

Update client configs to a channel:

npx -y ui-design-to-code-mcp@latest update \
  --clients cursor,claude-code,codex \
  --channel latest

Install a pinned version:

npx -y [email protected] install \
  --client codex \
  --package-spec [email protected]

Use pinned versions for stable production environments. Use @latest when you want the Codex daily updater or npx-based clients to pick up future releases.

Development

Run checks:

npm run check
npm run release:check

Package dry run:

npm pack --dry-run

Release

Recommended public npm release path:

Configure npm Trusted Publishing:

   node bin/ui-design-to-code-mcp.js configure-npm-trusted-publishing --dry-run

Trigger the GitHub Actions Release workflow from main.

The workflow uses GitHub Actions OIDC (id-token: write) and does not require NPM_TOKEN or a long-lived MCP Registry token. Keep npm account 2FA enabled.

For full release, registry, rollback, and security policy, see:
