"Free APIs and services without commercial fees" matching MCP servers:

Enables Claude to connect to Figma without a paid plan, offering auto-connect and 100+ tools for document manipulation, design system sync, and code-to-Figma conversion.

Connects an AI agent to Adobe Photoshop through COM/ExtendScript so it can build and correct designs —layers, typography, vector shapes, layer effects, blend modes, masks, adjustments and filters— while previewing its own output, inspecting a document's resources, and learning a reusable style from the user's finished PSDs.

Enables agents to search a fully local catalog of 21st-style shadcn components via full-text search, inspect individual records, generate reusable build prompts, retrieve install steps, and fetch design tokens for aesthetic keywords. Runs entirely offline over stdio with no API keys, paywalls, or rate limits.

Enables driving Inkscape headlessly from an MCP client, with verified SVG editing, rendering, optimization, and animation tools.

Enables an MCP-capable AI client to drive a locally installed, licensed Autodesk Inventor through its COM API for local modeling tasks. It supports creating and updating a rectangular plate and a parametric quickchanger concept assembly, opening and inspecting parts and assemblies, and returning viewport previews.

Enables agents to extract, inspect, search, and bundle design context from local Figma .fig files entirely offline, exposing frame summaries, node context, style tokens, assets, vector SVGs, and visual-match review via MCP.

Local MCP server inside 8 Autodesk apps (Revit, AutoCAD, Civil 3D, Advance Steel, Navisworks, Inventor, 3ds Max, Robot; 2023–2027): 480+ read/write actions, one-click setup for Claude, ChatGPT/Codex and Cursor. Commercial, free 14-day trial. Formerly HMK Pilot.

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.

Enables local image-driven displacement of STL/OBJ meshes, STL/3MF export, and agent-driven texturing workflows without remote services.

Local, free MCP server for brand logo search and shadcn/ui component search & source lookup, requiring no API keys or login.

Enables interaction with Figma tools and services through a standardized MCP interface.

Enables AI assistants to control Adobe Photoshop through natural-language requests for tasks like background removal, portrait retouching, web and social export, carousel creation, and batch watermarking. This privacy-focused fork supports a local, free Ollama provider so prompts and images can be processed without an API key or cloud account.

An MCP server that simplifies Figma design data, generates code in multiple frameworks, and provides accessibility audits and drift detection, all using a free Figma Personal Access Token without a paid Dev Mode seat.

MCP server providing 33 verified Motion for React APIs with correct imports and defaults, enabling AI assistants to generate accurate animation code.

Revit integration via Autodesk Platform Services — Extract elements, parameters, run schedules, detect clashes, export IFC.

Floor plans, elevations and sections for agents. Draw a room in real millimetres, place doors, windows and tables, validate with typed errors, render deterministic SVG. Free key, no approval.

Search, view, add, diff and update labsUI React components in a Next.js + Tailwind v4 project, and check its setup with doctor. Components are copied into your repo as plain TSX you own.

Deterministic "Rack-as-Code" 3D/2D CAD planner, 5-stage physical/PoE/acoustic validator, and parametric OpenSCAD/STL 3D-print generator for 10-inch mini-racks and 19-inch homelabs.

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.

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.

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.

Zero-dependency Python MCP server for coding agents (Antigravity, Claude Code, Cursor, Windsurf). Unfreezes 915+ skills on-demand, injects 74 brand design tokens (Linear, Stripe, Apple), and validates WCAG contrast.

MCP server for Unreal Engine 5, built into the editor: 2,000+ tools that let AI agents like Claude Code create and edit Blueprints, materials, levels, Niagara and animation, with every change read back and verified.

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.

Manages design tokens (colors, spacing, fonts) in a JSON file and enables agents to read, write, export, and detect drift between tokens and CSS via MCP.

Enables MCP hosts to inspect a published prototype through read-only tools for page structure, geometry, screenshots, and interaction evidence, including switching prototypes during a conversation.

Enables AI agents to generate Korea Government Design System components and page templates with KWCAG 2.2 accessibility requirements built in, then validate rendered pages and block task completion until remaining accessibility violations are corrected.
