"How to create an MCP tool" matching MCP servers:

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.

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.

Provides accurate competitive Pokémon information for Pokémon Champions, including damage calculation, type effectiveness, Pokémon data, and regulation legality checks.

MCP server for generating retro game sound effects using Bfxr synthesis. It provides tools to create, mutate, and load sound parameters, with output saved as WAV files and optional permalinks.

An MCP server for generating Pirate Borg NPCs with procedurally rolled stats, allowing LLMs to create stat-accurate characters using the rulebook's tables.

An MCP server that enables LLMs to build physically valid Lego models by enforcing catalog-only parts, no overlaps, stud-to-tube connections, and other real-world constraints.

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.

An MCP server for Dolphin (GameCube + Wii) — drives memory r/w, controller input (GameCube + Wii Remote), pause/resume/reset, savestates, and frame advance from MCP-compatible clients (Claude Desktop, Claude Code, etc.).

Enables offline, millisecond querying of a locally built SQLite snapshot of TibiaWiki, letting an agent resolve approximate page names, filter creatures and items by stats and damage modifiers, and find how any item is obtained via drops, vendors, or quest rewards. Every response reports when the index was generated, and no network calls are made.

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.

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.

An MCP server that lets an AI client enumerate and toggle the in-game menu of an Angel overlay for automated testing.

An MCP server adapter that allows LLM agents to autonomously play World of ClaudeCraft by wrapping the game's headless environment as MCP tools for state reading and action execution.

An MCP server that provides access to ESPN Fantasy Basketball APIs, enabling Claude and other MCP clients to fetch league teams, rosters, free agents, matchups, NBA schedules, and live draft assistant tools.

An MCP server that wraps the ThreeHats Foundry VTT REST API relay so an LLM agent can author and manage Foundry VTT content, primarily creating D&D 5e creatures, through native MCP tools.

MCP server for writing World of Warcraft addons, providing in-game Lua API references, Blizzard's UI source code, and game asset data to AI assistants.

Enables AI-assisted GameMaker project development in Cursor IDE, allowing users to create projects, add scripts, objects, and sprites using natural language.

A text-adventure interpreter as an MCP server. It enables the AI to act as the player, exploring, solving puzzles, fighting trolls, and collecting treasure through tool calls.
