"Understanding and Using JSON" matching MCP servers:

Render branded PDF documents (invoices, reports, certificates) and PNG social images directly from any MCP client using DocJet templates or raw HTML with JSON data.

Enables Claude Code to generate and preview rich user interfaces via the A2UI protocol, using declarative JSON components and real-time WebSocket updates.

MCP server that enables AI agents to operate FairyGUI Editor through structured tools, using a local JSON file queue and the editor plugin to invoke FairyGUI APIs.

Enables developers to extract and organize Figma design files, including complete node data (tree structure and images) for AI understanding and code generation.

MCP App that renders a json-render spec from the model as real Angular Material components inline in the chat (Claude, ChatGPT, VS Code, Cursor). One tool, render-ui, over a 29-component catalog; the UI renders while the model is still writing.

Enables AI agents to interactively remove image backgrounds using a Paint.NET-style magic wand tool with live visual feedback and precision helpers.

Enables AI agents to author designs as structured JSON scenes and render them to PNG, JPEG, WebP, vector PDF, animated PNG, GIF, MP4 or WebM at every target size, using one native binary with no browser or headless Chrome.

MCP server that extracts accessibility tree, design tokens, screenshots, Claude DSL, and Figma JSON from any URL using a persistent Chromium browser with zero LLM cost.

Enables AI agents to read and manipulate visual UI designs drawn on a canvas, translating them into precise JSON specs for production code generation.

Enables AI agents to automate AutoCAD drawings through a typed contract that drives either a live AutoCAD COM session or a headless ezdxf engine. It covers mechanical, architectural, and P&ID drafting, ISO GD&T and tolerance validation, standards-compliant sheets, and drawing understanding and takeoffs.

An MCP server that provides AI tools with deep understanding of WireUI v2.x components and comprehensive icon support for Heroicons and Phosphor Icons.

Gives AI agents one typed tool contract for CAD automation, driving either a live Windows drafting seat through COM or a headless DXF engine anywhere. It enables mechanical part sheets, P&ID drafting and reading, architectural floor plans, ISO GD&T and dimension-tolerance validation, plus drawing understanding and takeoff workbooks.

Gives AI coding assistants live access to the Hyperiux Vault catalog of React and Next.js animation effects. Search effects, inspect dependencies and installation instructions, and retrieve source for free effects.

MCP server for creating and editing diagrams using draw.io. Allows generating diagrams from Mermaid or XML, searching shapes, and opening them in draw.io for export.

MCP server that turns AI into an SVG artist. One rendering engine with a rich JSON schema, AI controls all design parameters. Renders animated SVGs with CSS @keyframes and SMIL animations. Supports 16+ element types, parametric curves, pattern groups, gradient/filter/clip/mask definitions, and PNG preview. No external dependencies, runs locally via npx.

Search 161,000+ free hand-drawn Infyicon icons in four matching styles and fetch ready-to-embed SVG markup or PNG URLs, plus CSS class lookup for the 61,000-glyph Infyicon UI webfont. Free with attribution, no API key required.

Analyzes and extracts design tokens, assets, and layout from live websites to enable AI clients to faithfully replicate them, with tools for screenshotting, component inspection, and pixel-diff verification.

Enables AI agents to manage routes on the Design Canvas infinite canvas app, including adding, removing, listing routes, and capturing screenshots of the canvas.

Enables searching, indexing, linking, and downloading 2000+ open-source fonts from fontsource.org, with support for font subsets, weights, styles, variable fonts, and CSS integration.

Read-only catalog of the @blueprint-modular/core design system (104 components). Four tools — list/search/get components and suggest compositions. Public, no auth, Streamable HTTP.
