Structured, constraint-aware visual generation and deterministic layout for AI agents
这三项永远不会合并成一个分数:意见、测量和人气是不同的东西。
我们还没有为它写通俗的介绍。下面是我们从注册中心读取到的事实。
选择你使用的 AI 应用,然后复制设置。
OPENAI_API_KEY, GEMINI_API_KEY标为机密的值是你账户的钥匙。千万不要分享给别人,也不要粘贴到聊天里。
你需要
你用的是哪个应用?
在上方选择你的应用。我们会记住它,下次按钮会显示“安装到 …”。
打开 Claude Desktop → Settings → Developer → Edit Config,把下面的内容粘贴到 claude_desktop_config.json
{
"mcpServers": {
"visualspec": {
"command": "npx",
"args": [
"-y",
"@utkarshx27/visualspec"
],
"env": {
"OPENAI_API_KEY": "your-value",
"GEMINI_API_KEY": "your-value"
}
}
}
}在终端中运行这条命令
claude mcp add visualspec --env OPENAI_API_KEY=your-value --env GEMINI_API_KEY=your-value -- npx -y @utkarshx27/visualspec运行前请先填写空着的值。
粘贴到项目中的 .cursor/mcp.json,或 ~/.cursor/mcp.json

],
"env": {
"OPENAI_API_KEY": "your-value",
"GEMINI_API_KEY": "your-value"
}
}
}
}浏览器会先询问是否打开应用,然后应用会显示设置并请你确认。密钥的值会留空,由你自己填写。

Deterministic visual generation for AI agents.
AI creates the imagery. VisualSpec guarantees the typography and layout.
# Instant workspace setup (no clone required)
npx @utkarshx27/visualspec init
npx @utkarshx27/visualspec mcp
Most image-generation workflows fail for social and marketing graphics because a single natural-language prompt is expected to handle too many concerns at once:
Image models frequently hallucinate gibberish text, truncate words, or disregard composition rules.
VisualSpec separates generative concerns from deterministic concerns:
User Brief / Intent
│ ▼ Visual Spec (spec.yaml) │ ┌───┴──────────────┐ ▼ ▼ Platform Pack Template Pack │ │ └───┬──────────────┘ ▼ Spec Resolver │ ┌───┴───────────────────────┐ ▼ ▼ Model Adapter Deterministic Layout (Generative Base) (SVG Typography / Overlay) │ │ └───┬───────────────────────┘ ▼ Compositor (Sharp) │ ▼ Visual QA (Constraints, Safe Margins, Exact Copy) │ ├── PASS ──► Final Asset Bundle │ └── FAIL ──► Targeted Repair Planner
# Initialize a new VisualSpec workspace
npx @utkarshx27/visualspec init
npx @utkarshx27/visualspec mcp
npm install -g @utkarshx27/visualspec
visual init visual mcp
git clone https://github.com/utkarshx27/visualspec.git
cd visualspec npm install npm run build
npx @utkarshx27/visualspec init
npx @utkarshx27/visualspec validate examples/product-launch/spec.yaml
npx @utkarshx27/visualspec compile examples/product-launch/spec.yaml --provider openai
Render layout, typography, and background styling locally:
npx @utkarshx27/visualspec render examples/product-launch/spec.yaml --output ./output/demo-launch
npx @utkarshx27/visualspec generate examples/product-launch/spec.yaml --provider mock --output ./output/demo-launch
npx @utkarshx27/visualspec check ./output/demo-launch/final.png --spec examples/product-launch/spec.yaml
VisualSpec runs as a native MCP server over stdio, enabling AI coding assistants (Cursor, Claude Code, Gemini CLI, and Antigravity IDE) to invoke visual tools directly:
# Launch MCP server over stdio
npx @utkarshx27/visualspec mcp
visual mcp
visual_brief_to_spec: Convert natural language requests into valid VisualSpec YAML.visual_validate_spec: Schema validation for specs.visual_render: Deterministic layout & typography rendering (zero API key).visual_generate: Full image model adapter + deterministic text overlay pipeline.visual_check_qa: Inspect safe margins, line counts, dimensions, and invariants.visual_repair: Automated diagnosis and localized typography/layout repair.visual_list_resources: List supported platform packs and templates.See the MCP Setup Guide for Cursor, Claude Desktop, and Antigravity IDE configuration snippets.
Every generation creates a complete, reproducible debug bundle:
output/demo-launch/
├── final.png # Platform-ready asset ├── visual-spec.yaml # Original input specification ├── resolved-spec.yaml # Full spec with platform & template rules applied ├── generation-request.json # Exact prompt and negative parameters sent to model ├── qa-report.json # Deterministic and constraint QA verification results └── metadata.json # Execution timestamps and file index
The framework includes 10 standardized skill definitions located in ./skills/:
using-visualspec: Master workflow instructions.visual-brief: Brief extraction and analysis.visual-spec: YAML authoring and schema rules.composition: Spatial hierarchy and negative space allocation.typography: Font family classing and line budgeting.strict-constraints: Invariant taxonomy and forbidden parameters.social-instagram: Instagram-specific design reasoning.social-linkedin: LinkedIn-specific design reasoning.visual-qa: Automated inspection and validation.visual-repair: Localized diagnosis and patch generation.We welcome contributions!
