Architecture & Design MCP Servers

Deterministic AI data-center design engine exposed as MCP tools (design, validate, layout): rack count, design PUE, total MVA, liquid/air cooling split, CDU planning, cost & timeline. NVIDIA Rubin-era, 22.9 kV intake, Korea. Remote Streamable HTTP at https://aidc-ai.io/api/mcp; no key for the anonymous tier.

Bidirectional Figma server over a local WebSocket relay: turn a selection into framework-aware code (reusing your components and tokens), or author frames, text, styles, variables, and whole screens back onto the canvas. 92 tools, any MCP client, no Dev Mode seat or paid tier.

A Model Context Protocol (MCP) server for validating Mermaid diagram syntax and providing comprehensive grammar checking capabilities

Catch bad animations before they ship. 13 deterministic checks on the live page (duration, easing, stagger, exits, reduced-motion, touch-gated hover) with no API key or LLM, plus optional vision-LLM UX review across viewports. Install via NPM: npx -y motionlint mcp

Generate beautiful Excalidraw architecture diagrams with auto-layout, architecture-aware component styling, and stateful editing. 50+ technology mappings including databases, message queues, caches, and more. No API keys required.

Local-first MCP server for AI-driven network design. Creates Cisco-style network master files, L1/L2/L3 topology diagrams, combined HTML viewers, device tables, and AI Context files.

Expose a company's complete design system (colors, typography, logos, components, guidelines, CSS tokens) to AI tools via MCP. Auto-parses CSS / Markdown / PDF / SVG / fonts; supports marketing vs product contexts with shared overrides; ships 12 tools, 16+ resources under brandkit://, and 4 prompts; stdio + SSE + Streamable HTTP transports. Install via NPM: npx -y brandkit-mcp serve.

MCP server for AI Diagram Maker — generate flowcharts, sequence diagrams, ERDs, system/network architecture, UML, mindmap, and workflow from natural language, code, ASCII, images, or Mermaid. Inline rendering using MCP Apps UI and editable diagram URLs. Requires API key.

Create workflow, sequence, and architecture diagrams using FlowZap Code DSL. 7 tools for validation, playground URL generation, syntax docs, graph export, artifact parsing, diffing, and patching. No API key required. Install via NPM: npx -y flowzap-mcp

MCP server that turns local projects or GitHub repositories into Mermaid diagrams and renders them via Kroki.

Expert design & marketing knowledge for web / iOS / Android / macOS UI/UX: 83 sourced, prescriptive docs plus deterministic generators (design tokens, color systems, type scales, WCAG a11y) and a one-call create_design_system. Offline, no API key, reads only local files. Install via NPM: npx -y saglitzdesign-mcp.

Generate premium iOS mobile UI mockups (PNG + HTML) from a single text prompt. Pairs Claude (Opus 4.7 by default) with a Playwright headless renderer. Two backends — claude CLI (uses your Claude Code subscription) or Anthropic API. Stdio + HTTP transports, MIT.

Construction plan takeoff on stdio — load a plan PDF, read the title block, adopt the drawing scale (never applied silently), one-click trace rooms, and export real-world quantities (square footage, linear feet, counts) with provenance receipts. Install via NPM: npx -y opentakeoff-mcp

AI-powered Mermaid diagram generation with 22+ diagram types including flowcharts, sequence diagrams, class diagrams, ER diagrams, architecture diagrams, state machines, and more. Features 50+ pre-built templates, advanced layout engines, SVG/PNG/PDF exports, and seamless integration with GitHub Copilot, Claude, and any MCP-compatible client. Install via NPM: npm install -g @narasimhaponnada/mermaid-mcp-server

"Mermaid for human movement" — a text language any LLM can write, rendered as a safe, anatomically-clamped 3D human figure in the browser.

AI-native architecture platform for engineering teams. Describe a system in natural language (e.g. "payment service with Stripe, Kafka, PostgreSQL") → get an interactive typed diagram with 167 cloud components → export to 14 production frameworks (Java Spring Boot, Python FastAPI, Go chi, Rust Axum, .NET, Kotlin Ktor, Ruby Rails, Elixir Phoenix, Docker Compose, Terraform, Mermaid, ADR, and more). Drift detection (sync_architecture) scores saved diagrams against live code 0–100 with a structured diff. 9 quality-lint rules catch orphans, SPOFs, god services. Also includes a secondary persistent code-graph layer for AI coding agents (free offline via npx tentra-mcp --local init). Agent-as-LLM pattern — zero LLM cost on our side, zero API key on yours. 35 MCP tools. Works in Cursor, Claude Code, Codex, Windsurf.

A complete color workflow over MCP: mix (incl. Kubelka-Munk paint physics), convert formats, generate harmonies, and remember named palettes. Resolves hex, CSS, and custom brand color names, and refuses unknown colors rather than guessing. Hosted, no install: https://rnvizion-rnv-color-mcp.hf.space/mcp.

Agent-native UI/UX design validation: model user journeys as state machines and prove what AI-generated screens are missing (unreachable states, missing empty/loading/error states, WCAG contrast, touch targets, localization overflow) before code exists — then verify the code implements the contract. Deterministic CI gates (uxloom check, uxloom audit), one-command setup (npx uxloom init).

Let your AI author Mermaid diagrams (flowchart, sequence, ER, mindmap) in a shared workspace, then read, comment on, embed, and present them at a clean URL — instead of pasting back hundreds of lines of prose. Hosted endpoint https://mcp.diagramzu.ai/mcp or local npx -y @diagramzu/mcp. 14 tools incl. diagram CRUD, version history, comments, presentation decks, and analyze_diagram lints.
