"How to connect through SSL" 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 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.

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 AI agents to query Roblox experience analytics such as DAU, revenue, retention, performance, and funnels through the Open Cloud API.

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.

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

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

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.

A local MCP server that lets AI agents manage Roblox developer products and game passes through the Open Cloud API.

Enables D&D Beyond integrations through MCP by reading character sheets, monster statblocks, and campaign rosters, plus streaming live game-log dice rolls with optional write tools for HP and conditions.

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.

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.

Enables querying Lineage 2 private server openings by chronicle through the public L2 Calendar API from any MCP client.

Enables reading ESPN fantasy football league settings, rosters, free agents, matchups, and transactions, and managing lineups, adds/drops, and waiver claims through MCP tools over stdio.

Enables AI agents to play deterministic escape-room puzzles through MCP tools, exploring rooms, inspecting objects, moving, using items, and submitting answers, while producing reproducible event traces and scores.

MCP server for reading and exporting GameMaker data files via UndertaleModCli. Enables entity listing, decompilation, and export through clean JSON output.

An MCP server that allows Claude and other hosts to interact with a Heroic Labs Nakama instance through both its Client API and Console API, enabling game server operations like authentication, accounts, storage, leaderboards, and admin tasks.
