Enables querying GoldSrc game servers (e.g., Half-Life, Counter-Strike 1.6) for server info, player lists, rules, and RCON commands.

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.

Lets AI assistants control the physical Return to Dark Tower board game tower via Bluetooth, enabling connection, calibration, sound, lights, drum rotation, seal breaking, and game sequences through natural language.

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.

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 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.

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

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.

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 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 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 Claude to read Crusader Kings III save files and retrieve strategic game information such as realm overview, military, succession, diplomacy, vassals, factions, and expansion options.

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.

Provides read-only Arknights intelligence over MCP, enabling structured queries about stages, enemies, operators, and modules with region tagging and evidence-backed analysis. It uses versioned SQLite snapshots and never fetches upstream data at query time.

Enables AI agents to create, render, and validate 3D scenes, 2D art, and games in HTML canvas using Three.js, WebGL, or Canvas 2D, with multi-angle screenshots, structured validation reports, and interactive playtesting.

Lets Claude join a real match of the shooting game as the second player and play it through a live browser, reading the arena and sending actual keyboard inputs to move and shoot.

Enables AI to create and publish interactive web apps, games, and 3D scenes using Rosh, a plain-English programming language. It supports compilation to HTML5 canvas, Phaser, or Three.js.

Enables AI assistants to compare keyboard sizes and layouts, look up measured dimensions of 30 reviewed keyboards, and check whether a keyboard plus mousepad fits on a desk, including a 360° turn at a given sensitivity. It also reports which sizes have a specific key and searches keyboard reviews, linking answers to to-scale layouts.

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 AI agents to search, read, and publish Minecraft mods on Modrinth, including creating projects and uploading jar files as new versions.

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.

An MCP server that exposes a live Dwarf Fortress fort to an AI agent as a small set of curated, semantic tools — a fortress co-pilot and early-warning advisor, not an autopilot. It provides read-only sensors and reference tools to observe the game state and retrieve game data.
