Common questions

Is VisualSpec safe?

It passed 3 of 3 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?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed 2 months ago, and the latest version (0.1.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

VisualSpec

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

Launch local MCP Server for Cursor, Claude Desktop, or Antigravity

npx @utkarshx27/visualspec mcp

The Core Problem

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:

subject & background
exact typography & wording
platform dimensions & safe margins
visual hierarchy & negative space
brand color rules & constraints

Image models frequently hallucinate gibberish text, truncate words, or disregard composition rules.

The Solution: Layer Separation

VisualSpec separates generative concerns from deterministic concerns:

Generative Layers (AI Models): Photography, 3D subjects, atmospheric backgrounds, textures, lighting.
Deterministic Layers (Code & SVG Engine): Exact headlines, subtitles, badges, logos, metrics, safe margins, and layout rules.
Structured Visual Spec: A machine-readable YAML specification that acts as the single contract.
Visual QA & Targeted Repair: Verifies geometry, margins, and exact copy invariants, synthesizing localized repairs without regenerating entire scenes.

Documentation

Quickstart

Instant Run (No Install Required)

# Initialize a new VisualSpec workspace

npx @utkarshx27/visualspec init

Launch local MCP Server for Cursor, Claude, or Antigravity IDE

npx @utkarshx27/visualspec mcp

Or Install Globally

npm install -g @utkarshx27/visualspec

Use CLI commands directly

visual init visual mcp

Or Build from Source

git clone https://github.com/utkarshx27/visualspec.git

cd visualspec npm install npm run build

1. Initialize a Project

npx @utkarshx27/visualspec init

2. Validate a Visual Spec

npx @utkarshx27/visualspec validate examples/product-launch/spec.yaml

3. Inspect the Compiled Generation Prompt

npx @utkarshx27/visualspec compile examples/product-launch/spec.yaml --provider openai

4. Deterministic Render (No API Key Required)

Render layout, typography, and background styling locally:

npx @utkarshx27/visualspec render examples/product-launch/spec.yaml --output ./output/demo-launch

5. Run the Full Generation Pipeline

npx @utkarshx27/visualspec generate examples/product-launch/spec.yaml --provider mock --output ./output/demo-launch

6. Verify Asset Quality with Visual QA

npx @utkarshx27/visualspec check ./output/demo-launch/final.png --spec examples/product-launch/spec.yaml

Model Context Protocol (MCP) Server

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

Or if installed globally

visual mcp

Available MCP Tools

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.
