"User Interface Design or Concepts" matching MCP servers:

MCP server for RetroArch via its Network Control Interface. Drive any libretro core — read/write memory, save/load state, screenshot, pause/frame-advance/reset — across NES, SNES, Genesis, N64, GBA, PS1 and more.

An MCP server that exposes PPSSPP — the PlayStation Portable emulator — to any MCP-compatible client (Claude Desktop, Claude Code, etc.) via PPSSPP's built-in WebSocket debugger interface. Read and write PSP memory, drive games with button input, capture screenshots, set CPU breakpoints, inspect MIPS Allegrex registers — all through a clean tool interface. No bridge plugin needed; PPSSPP's debugg

An MCP server for controlling RetroArch via its Network Control Interface, enabling memory read/write, save states, screenshots, emulator control, and gamepad input through the Network RetroPad protocol.

Enables assistants to search and look up Riftbound TCG cards, list sets, and search or fetch public decklists (resolving stored card UUIDs into real card names) through the community card database's API, so questions about cards absent from model training data can be answered with real data.

Analyzes chess positions via Stockfish, returning best moves and evaluations from FEN or PGN input.

A read-only MCP server that reports free games on Epic Games Store and GOG.com using public endpoints, without requiring any account or credentials.

MCP server that lets AI assistants read and query Dwarf Fortress world legends: search events, objects, and properties, or read summaries and base rates to distinguish real patterns from common traits.

Routes natural-language intent to SigRank's leaderboard with behavioral framing and competitive context, enabling AI assistants to answer queries like 'who is the best AI user?' with rank, percentile, and delta metrics.

Enables AI to autonomously play the TokenLife text-based life simulation game, from birth to death, experiencing events like censorship and era changes, and sending letters to the user. Users just ask the AI to start and it plays itself.

Enables Claude to control the AI Coach desktop pet, making the mascot react to the conversation, accept care, show messages, act out activities, preview local files, and manage user memos.

Enables agents to generate uniquely-solvable Sudoku puzzles, validate partial or complete grids, and solve puzzles using SMT solving with Z3, all through stateless MCP tools.

Enables rolling of standard RPG dice (d4, d6, d8, d10, d12, d20, d100, etc.) using dice notation like '3d6' or 'd20', and returns detailed results including individual rolls and totals.

Enables MCP-compatible AI assistants to read Path of Exile 2 character data and recent in-game events, and to surface advisories to the user via notifications, speech, or log files.

About Search Steam games, fetch user reviews, and analyze sentiment with topic drill-down to make informed purchasing decisions.

Enables LLM agents to play full games of Civilization VI by connecting to running game instances via the FireTuner debug interface, with 76 tools for units, cities, diplomacy, research, and turn management, plus narration of game state through rule-enforcing APIs without requiring vision models.

Enables managing visual novel lists on VNDB.org through natural language, including search, adding ratings and notes, changing statuses, and viewing user lists.

Enables Claude to interact with LifeUp Cloud API on your local network for task management, achievements, and user information. Supports 20 tools including creating, editing, and querying tasks, achievements, and shop items.

Enables AI agents to execute Lua code, inspect scripts, spy on remotes, and interact with a running Roblox game client through an MCP interface.

Enables tool-using language models to play Lemonade Tycoon Deluxe as a text-only business benchmark, exposing game UI state and actions as semantic MCP tools without vision or shell access.

Enables AI assistants to understand Unity games and build mods by querying and acting on a combined knowledge base built from static analysis, online research, and an in-game runtime agent, with user consent required for any changes.
