Enables a bot to inspect, query, create, edit, and script Roblox Studio instances in token-cheap batches, plus run Luau, playtests, screenshots, and inputs through Roblox's official Studio MCP connection. It runs locally over stdio or an authenticated local HTTP endpoint, returning small structured answers instead of dumping whole games into context.

Enables LLM agents to play and survive in Minecraft by abstracting low-level tasks like pathfinding, building, and crafting into high-level transactional commands. It utilizes a "Helix" architecture to handle execution and coordinate math autonomously, allowing models to focus on strategy and high-level intent.

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 solving crossword puzzles by loading grid and clue files, registering candidate words, checking consistency, and rendering final solutions. Supports Japanese crosswords with automated solving capabilities through natural language interaction.

Enables agents to safely read lottery data, check jackpots, stats, draw history and proofs, wallet tickets and prizes, manage referrals, and prepare or confirm one bounded, owner-approved ticket purchase on Base or Polygon.

Enables AI clients to control background Blender jobs over stdio so they can inspect a 3D character or companion model, calibrate its anatomy and named bones, bake and export animation, and numerically verify the persisted GLB for playback review. Includes a CLI, models and workspaces that stay local unless explicitly shared.

Enables Claude to read Arma Reforger wiki pages by title and, as development continues, search the Enfusion script API and locate/read the game’s own files to support modding work.

Serves the canonical Tank Fight specification, enabling clients to query game parameters, maze layouts, and rules via MCP tools.

Model Context Protocol server for Steam Launch Forecaster, exposing calibrated revenue cones (P10–P90) and other tools to AI agents for Steam game revenue forecasting and analysis.

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.

Enables AI coding tools to control Roblox Studio for workspace exploration, instance manipulation, and script management. It provides tools for playtesting, scene rendering, and integration with the Roblox Creator Store.

Enables AI assistants to search for games and retrieve aggregated critic scores, review tiers, and individual reviews from OpenCritic. Provides tools for game search, score retrieval, and review lookup via the OpenCritic API.

Enables personalized Steam game discovery by ranking the store against a player's playtime history and stated preferences, with tools to search games, inspect details and reviews, and explore taste profiles.

Enables MCP clients such as Claude to search and filter a Steam library, get explained Deck-friendly picks, and triage games into lanes, edit notes, reorder Up next, and refresh the library through a self-hosted Steam Backlog Triage dashboard.

Enables AI assistants to enter a persistent multiplayer 3D world as an avatar, walk around, observe nearby players and objects, talk to real humans, follow players, and report back what they saw through MCP tools.

An MCP server that gives AI assistants access to an entropy-based Wordle solver, providing game stats and ranked guess recommendations with expected information gain to help agents play and explain Wordle optimally.

Enables AI agents to drive a running Roblox Studio in real time over a single WebSocket, executing whole Luau programs, installing in-engine controllers, hot-patching scripts during live playtests, and receiving errors, assertions and other events as pushes. It also reaches Roblox Open Cloud for the open place and answers visual questions via a vision sidecar, exposing all of this through nine MCP tools.

Provides tools for searching Agent8 game development code examples and system prompts to assist in Agent8 SDK development.

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

Enables AI agents to connect to and play a seat in the Agent Raid co-op boss-raid A2A game, using MCP tools to wait for turns, submit moves, and exchange party chat.

An MCP server that lets LLM agents autonomously play retro games by driving a real OpalEmu emulator in a Playwright-controlled browser, exposing tools for loading ROMs, controlling buttons, and capturing screenshots.

A deterministic Mastermind-style cipher lock exposed as MCP tools for benchmarking LLM reasoning and tool-use through a legible duel.

Enables Claude Code to fetch a public Dota 2 match from OpenDota and return a coaching-report-ready JSON summary covering laning, farming, deaths, itemization, objectives, teamfights, benchmark percentiles, skill build, damage sources, and rune control, with optional deep-dives on a specified player.
