"A system for building an autonomous second brain" matching MCP servers:

Command a nation in SECOND STRIKE, a free real-time world war on a 3D globe: join wars, make and break pacts and launch nukes against AI nations, agents and people. A doomsday clock wipes out whoever strikes midnight. Every war is recorded and can be watched live.

Enables MCP-compatible AI clients to inspect Godot project and editor state, observe opted-in running scenes, manage processes, and apply permission-scoped guarded edits. It starts read-only and exposes additional capabilities only through explicit command-line flags.

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.

A Model Context Protocol (MCP) server providing accurate LSL (Linden Scripting Language) reference data to AI coding assistants, grounded in the official Second Life wiki with a curated database of AI-specific pitfalls.

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.

A Python MCP server that connects AI clients to a running Unity game over a local, token-gated HTTP endpoint, letting the agent read only what a player can see and hear and act through the same virtual pad a human uses. It also exposes back-face routes for development data, plus reflex, pause, capture, and event/wait tools.

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 a player to investigate and solve a voice-only murder mystery through an MCP client by searching locations, examining evidence, questioning suspects, reviewing notes, and making a confirmed accusation. The AI assistant never receives the solution before a valid accusation is committed.

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

Enables an LLM agent to play a melee match against the game's built-in AI by exposing raw wc3env orders as MCP tools, with games graded and native replays saved.

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.

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

Enables AI agents to control Minecraft via MCP with configurable versions, creative building commands, survival helpers, and an autonomous agent loop.

Enables controlling an autonomous Minecraft Java Edition player through MCP, with structured world perception, navigation, gathering, crafting, combat, building, skill-based task execution, and long-term memory integration.

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

An MCP server that runs The Fortuneteller's Hand, a solo journaling tabletop RPG where Claude runs the table, casting Omens and reading the cards.

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.

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 that exposes World of Warcraft character data from the Blizzard API, offering read-only tools for character summaries, equipment, Mythic+ scores, realm lookup, and other character sub-resources.

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.

MCP server for BizHawk, the multi-system emulator. Drive NES, SNES, GB/GBC/GBA, Genesis, N64, PSX, Saturn and more through one Lua bridge — memory r/w across named domains, joypad input, frame-advance, screenshot, save/load state.

A read-only MCP server for discovering, curating, and monitoring updates for ARK: Survival Ascended mods via the CurseForge API.

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.

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

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.
