Enables rigging, animation, and VFX workflows for Roblox through an MCP-compatible chat client, connecting Blender and Roblox Studio for tasks like skeleton fitting, keyframe editing, particle effects, and FBX export.

Enables users to translate geometric bounding boxes, flowchart node connections, and architectural sketches into clean Mermaid graphs, JSON topology matrices, and boilerplate code scaffolds through MCP.

Generates editable Excalidraw diagrams from natural language system descriptions, with properly bound arrows and labels. Includes tools for diagram creation, validation, and backend status.

Provides AI assistants with frontend development tools including component scaffolding, bundle analysis, accessibility checks, and responsive design guidance. Enables automated generation of React components with tests and stories, bundle optimization recommendations, and WCAG compliance fixes.

Enables AI clients to create, edit, read, and export Microsoft Visio diagrams via COM automation on Windows.

A comprehensive MCP server for Vue component development and Figma design restoration, featuring snapDOM-powered screenshots, pixel-perfect visual comparison, and automated SVG optimization.

Enables conversion of Figma designs into frontend code (React, Vue, HTML, etc.) with high fidelity, including design tokens, assets, and responsive layout. Integrates with AI editors via MCP for a seamless design-to-code workflow.

Aggregates GitHub, GitLab, and Figma development tools via MCP, enabling file access, code search, and design inspection. Also supports executing standalone tasks with Claude Code or Codex CLI.

Provides AI-powered tools for UX/UI review, web component generation, and code refactoring using Google Gemini.

It lets agents discover enabled TFMSTYLE Blender addons and their actions/settings, then apply validated settings or run safe addon actions inside a running Blender.

Enables AI assistants to create and edit pixel art and animated sprites in Aseprite through 104 tools covering drawing, layers, animation, palettes, tilemaps, exports, visual analysis, and raw Lua scripting.

Enables AI assistants to control Aseprite for creating pixel art and animated sprites, with 104 tools covering canvas, drawing, animation, palettes, effects, and more.

A Python MCP server that gives AI assistants full control over Aseprite for creating pixel art and animated sprites. It provides 104 tools across 17 categories for canvas, drawing, layers, animation, palettes, effects, and more.

An MCP server that enables AI assistants to programmatically create and manage use case diagrams (actors, use cases, subjects, relationships) in StarUML via a REST API.

Enables Claude Code and Claude Desktop to control Adobe Photoshop on Windows through high-level, tested tools for non-destructive object cutouts, dismissing hint popups that block scripting, and related automation.

Enables AI agents to diagnose, modify, and validate OTF/TTF fonts interactively through a set of read-only, write, and validation tools.

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.

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.

Enables designing labels for NIIMBOT thermal printers and previewing exactly what the printhead will burn, since each design is rendered offline with NiimBlue's own code in headless Chrome and returned as a 1-bit PNG with layout warnings. It also returns an open-in-app link so the label can be reviewed and printed from NiimBlue, without the server ever touching a printer.
