MCP Servers

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 analyzediagram lints.

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).

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.

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

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

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 createdesignsystem. Offline, no API key, reads only local files. Install via NPM: npx -y saglitzdesign-mcp.

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.

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

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.

🎖️ - 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.

Conversational Spotify control with intent-shaped tools: play by description, queue, devices, playlists, and library, plus a 2-minute PKCE setup wizard. Built for the post-Feb-2026 Spotify Web API. npx -y @xavifabregat/spotify-mcp

Generate, edit, and upscale AI video & images (Seedance, Veo, Kling, FLUX, Nano Banana) from any agent via VicSee.

Music metadata search over 90M+ tracks, artists, labels, and releases: genre, release dates, ISRC/ISWC codes, and cross-platform IDs (Spotify, Apple Music, Tidal, Beatport, Discogs, MusicBrainz, YouTube). npx -y sonovault-mcp

First-edition identification — points of issue, number-line decoding, and publisher rules over a CC-BY, DOI-cited dataset of 6,717 titles — plus New Mexico book-donation logistics. Hosted remote server, no auth. Endpoint: https://newmexicoliteracyproject.org/api/mcp · Registry: org.newmexicoliteracyproject/nmlp-mcp

🎖️ - Create real, shareable memes from 25,000+ templates on memebo.at. Search the catalog, caption a template, get a live meme URL back. Free, anonymous, no API key. Remote server at https://memebo.at/mcp or npx -y memeboat-mcp.

🎖️ - Official LabelGrid server — manage your music distribution catalog, releases, analytics and royalties from any MCP client.

Discover Kavel’s AI photo/video generators (hairstyle, figurine, pet portrait, wedding, 90s yearbook, dance video, HD restore), get model-tuned prompts, and open the right tool to generate on www.kavel.ai. npx kavel-mcp

Deterministic music-theory server: chord & Roman-numeral analysis, voicing, and reharmonization — computed, not hallucinated. Hosted at mcp.thiri.ai, no third-party account required. npx @bluesprincemedia/thiri-mcp

Local MCP adapter/server for browser-only image workflows. Resize, compress, convert, remove backgrounds, strip metadata, watermark and export image packs through QuokkaPix without uploading source images to a processing server. npx quokkapix-mcp

Search the Archive of Our Own (AO3) and delegate full-fic reading to a secondary model (Gemini), so the agent recommends from the actual text, not the author's blurb. pip install ao3-mcp

🎖️ - Hire a real human operator for tasks that need physical presence, perception, or judgment: real-world verification, product testing, AI output review, data collection, and local errands. Remote streamable HTTP at https://humanforai.dev/mcp or local stdio via npx -y humanforai.

Remote Streamable HTTP and local stdio MCP server for defining, validating, deploying, and operating machine-readable agreements with EIP-712 permit preparation, signed participant inputs, state reads, and input history.

🎖️ - Search 419,000+ space regulatory filings from FCC, ITU, UNOOSA, and FAA — semantic search, entity dossiers, spectrum holdings, launch licenses, and filing alerts, powered by Orbit Sentinel. brew install --cask viventine-space/tap/orbit-sentinel-mcp

🎖️ - Discover, invoke, and cryptographically verify AI agents on a paid agent marketplace. 13 tools spanning code generation (6-module engineering verification), security scanning (OSV.dev + GitGuardian), and lead scoring (8 real sources). Every result is Ed25519-signed and independently verifiable -- no trust in the platform required. Install: npx -y @forcedream/mcp-server.
