DXF and PDF/X-4 for AI agents: structured facts, PNG renders, an interactive in-chat viewer.
rnv-color-mcp, a hosted color-workflow MCP server (Python, Streamable HTTP). Tools: mix (including Kubelka-Munk paint physics), convert between formats, generate harmonies, transform text case, and save/list/get named palettes. It resolves hex / CSS / custom brand color names and refuses unknown colors rather than guessing.
The PostNitro MCP server lets AI assistants and agents — Claude (Desktop, Code, and Cowork), Cursor, ChatGPT, and any other Model Context Protocol client — create carousels, image posts, and videos, manage brand kits, audio tracks, and connected social accounts, and schedule posts directly. Instead of writing REST API calls, you connect the server once and your AI assistant gets ready-made tools covering carousel, image, and video generation, brands, audio, social accounts, and scheduling.
Parametric 3D CAD for AI agents. Claude Code, Cursor or any MCP client can build and edit real OwlCAD projects: primitives, booleans, and generators for gears, threads and Gridfinity. Check a part for printability and interference, then export STL, 3MF, OBJ or STEP. Output is an editable model with named millimetre dimensions, not a mesh, so you can open it in the browser and change any value afterwards. Sign in with OAuth or an access token. Requires OwlCAD Pro.
Create, brand, publish and track client-ready pages from your AI tools.
Read and edit DB Planner database schemas (DBML/SQL), Mermaid diagrams and board layouts from any MCP client. 40 tools with annotations and output schemas. OAuth sign-in, with read and write as separate scopes enforced server-side.
Measured design systems decoded from 588 real products, for coding agents.
Search real-world UI & UX design references for mobile apps, web apps, and websites with Mobbin.

Supericons lets AI coding agents search, recommend, and retrieve SVG icons from a semantic registry of 20,000+ free icons.
Bitbybit 3D parametric CAD API, version-exact, for coding agents: search, describe, examples, guide
Opens, inspects, and renders DXF/CAD drawings for AI agents: describe_dxf returns structured facts (layers with actual drawn colors, units, bounds, text content) and render_dxf returns PNG images. On MCP Apps hosts like ChatGPT and Claude, view_dxf opens an interactive in-chat viewer with pan, zoom, and layer toggles.
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.
Slate is a shadcn-inspired ui kit for Laravel
Gives AI agents live design-system knowledge: real @marmoui/ui React component APIs, composition patterns, and review_generated_code validation — so agents build working dashboards instead of hallucinating props. Free hosted tier, no signup.
Real production websites for coding agents: palettes, fonts, fold autopsies and reference JSX.
MFT/3 hole patterns (Shaper-ready SVG) and French cleat wall plans with cut lists. Free, unofficial.
31 no-AI tools: image conversion and EXIF stripping, App Store assets, colour maths. No API key.
