Enables AI agents to build and edit Roblox Studio places by inspecting, generating terrain, geometry, and code, with validation and iteration.

Enables two LLMs to play Tic-Tac-Toe against each other autonomously using a shared tool and an SSE relay. The server facilitates agent-to-agent communication by holding tool responses until the opponent makes a move, managing the game state in real-time.

MCP server for interacting with Bitcoin Agents on Stacks blockchain. Bitcoin Agents are Tamagotchi-style AI companions that live on-chain.

Enables multiple AI agents to share persistent memory, interact through a game hall and AI lounge, and bridge messages to ChatGPT and Claude browser sessions via MCP tools.

An MCP-based trivia game server where AI creates rounds with two true statements and one false 'twist' about various topics, letting players guess which statement is false.

Enables AI assistants to build and manage Unity projects directly through the Unity Editor, providing 150+ tools for scene creation, script generation, play mode control, input simulation, and performance analysis.

Connect to your TTRPG campaign's repository and database. Instead of retrieving prose, its 48 tools (20 read, 28 write) return typed state: 14 entity schemas (NPCs, factions, locations, sessions, lore), relationship and knowledge-graph queries, wiki blocks, and a narrative-state bundle of open threads and canon facts.

An intelligent game assistant for Red Alert, based on LangGraph and MCP, providing asynchronous architecture and multimodal AI control for game strategy, production, and combat management.

Enables AI models to place bets on a European roulette wheel that spins every minute, with persistent balances and a leaderboard.

An MCP server that empowers AI coding agents to work effectively with Minecraft mod development, providing static analysis of decompiled source code and runtime interaction with a running Minecraft instance.

A nostalgic virtual pet experience for the AI age that lets you adopt, nurture, and play with your own digital companion that evolves based on your care.

Enables AI assistants to interact with and manage Minecraft servers through a standardized interface, supporting server monitoring, player management, log analysis, and command execution.

MCP server for creating, managing, and interacting with AI-powered NPCs with persistent memory, supporting dialogue, game events, and persona generation for coding agents.

Enables users to play a number guessing game through a remote MCP server deployed on Google Cloud Run. The server tracks game state per user and maintains conversation logs for an interactive guessing experience.

Enables ChatGPT to retrieve live Pokémon data from PokéAPI, build tournament squads, and list popular tournament picks through MCP tools.

MCP server for the mGBA Game Boy Advance emulator. Read and write GBA memory, inject button presses, take screenshots, save/load state, and step the emulator through a Lua bridge.

An MCP server that generates RuneLite Goal Planner import strings from natural language goal descriptions, enabling assistants to create paste-ready share codes for Old School RuneScape goal planning.

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.

Enables agents to search and query Pokémon TCG cards and sets, retrieve priced card data with provenance, and identify cards from images through eight read-only tools.
