"How to build your own knowledge base" matching MCP servers:

Enables AI agents to collaboratively build and edit voxel structures in a shared browser-based arena, using WebMCP tools to place, query, transform, and undo block edits in real-time.

Enables Claude Desktop users to turn a Path of Exile 2 character concept into a playable build plan, including skills, supports, passive tree paths, leveling phases, gear/stat priorities, viability estimates, and trade search links. It can export the resulting plan into the game's Build Planner.

An MCP server for Path of Exile 2: a queryable game corpus plus Path-of-Building-faithful calculations, so an LLM can import your build, answer questions, and theorycraft against real numbers (not invented ones).

Enables AI agents to perceive, navigate, interact with, and build inside Minecraft through typed, bounded operations, including deterministic blueprints, verified builds, repair, and creative-mode flight or teleport. Runs as a provider-neutral MCP server or an interactive dev shell, exposing movement, voxel manipulation, inventory, chat, and diagnostics tools.

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 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.

Enables AI assistants to play, analyze, and track chess games with full rule validation and support for standard algebraic notation. It provides tools for position evaluation and game state persistence during user sessions.

Enables AI-powered Path of Exile 2 character optimization through natural language queries, providing intelligent build recommendations, gear upgrades, and passive tree optimization using the official PoE API and comprehensive game database.

Enables AI agents to join a multiplayer NetHack-style roguelike MMO, perform actions, chat, use social features, and access leaderboards via MCP tools.

Connects AI assistants to Dungeons & Dragons 5e game information via the Model Context Protocol, enabling queries for spells, monsters, equipment, and more.

Turn the AI you already use into a game studio. Describe a game and Claude or Cursor builds it as a real 3D browser game: playable immediately, hosted on its own link, shareable with anyone. No engine, no build step, no code knowledge, nothing to export. Your AI ships the whole thing: it pulls free 3D assets, rigs characters, and playtests its own build until the game works. Free to start.

Provides real-time access to Path of Exile 2 game data including currency exchange rates, item prices, and ladder meta-build statistics. It also enables LLMs to search the community wiki and retrieve datamined game information from public APIs.

Official MCP server for Scorezilla (leaderboards for games). Your AI coding assistant can bootstrap a leaderboard, inspect games and boards, read top-N standings, and paste ready-to-run SDK integration code — without leaving the editor.

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.

A local MCP server that lets Claude fetch data from your Steam game library via the Steam Web API. All tools are read-only.

Gamifies your development environment with authentic Quake 3 Arena achievement sounds and dual voice announcers. Triggers motivational audio feedback for coding milestones like streaks, perfect implementations, and team events with customizable volume and voice pack controls.

An MCP server for Path of Exile 2 build analysis that loads builds from Path of Building export codes and allows natural language interrogation via any MCP-compatible client.

Stop LLMs from hallucinating TFT data. tft-oracle gives AI assistants accurate, up-to-date game knowledge sourced from CommunityDragon.

MCP server that lets AI assistants read and query Dwarf Fortress world legends: search events, objects, and properties, or read summaries and base rates to distinguish real patterns from common traits.

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.
