"Reliable sources for use in training language models" matching MCP servers:

Unifies Roblox Studio, Unity, Unreal Engine, and Blender into a single AI-powered control plane with 78 tools for automated game development.

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.

This MCP server provides real-time integration between Elite Dangerous and Claude Desktop, enabling AI-powered analysis of your gameplay data and dynamic generation of EDCoPilot custom content.

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.

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

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

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

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 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 querying Dota 2 player statistics, match data, and hero information through the OpenDota API using natural language.

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.

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.

An MCP server that bridges any MCP-capable AI host to Roblox Studio. The AI executes Lua live in Studio, reads output/errors, and iterates.

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