"A guide to developing Chrome extensions" matching MCP servers:

MCP server that helps AI agents inspect Minecraft project evidence (crash logs, mod files, datapacks) before writing development code.

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.

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.

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.

Enables AI clients to control background Blender jobs over stdio so they can inspect a 3D character or companion model, calibrate its anatomy and named bones, bake and export animation, and numerically verify the persisted GLB for playback review. Includes a CLI, models and workspaces that stay local unless explicitly shared.

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 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.

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.

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.

Enables AI assistants to compare keyboard sizes and layouts, look up measured dimensions of 30 reviewed keyboards, and check whether a keyboard plus mousepad fits on a desk, including a 360° turn at a given sensitivity. It also reports which sizes have a specific key and searches keyboard reviews, linking answers to to-scale layouts.

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.

Enables AI agents to search and read source-grounded entries about Minecraft farms and contraptions, including inputs, outputs, labor steps, version applicability, and verification records. It provides two read-only tools and runs offline without accessing a game or executing builds.

Enables an agent to consolidate repetitive Moonlight Garden chores into a single call, view a read-only farm, coop, and bee status summary, and check which recipes are cookable from live inventory against a locally maintained ledger of high-value dishes. It aggregates and trims results rather than making game decisions for the user.

Enables AI assistants to monitor a Sleeper fantasy football draft in real time by retrieving draft picks, available players, current turn, and roster needs through Sleeper's public keyless API.

Enables AI agents to create and update live two-team scoreboards, keep score, and share spectator links after securely connecting a user's account.

Enables agents to interact with a running Roblox game client, execute Lua code, inspect scripts, spy on remotes, and more.

Exposes tic-tac-toe game tools (new_game, get_state, make_move) for Claude to play against a human via chat.

Enables AI agents to execute Lua code, inspect scripts, spy on remotes, and interact with a running Roblox game client through an MCP interface.

A Model Context Protocol server that gives AI assistants real-time access to the MCSR Ranked competitive Minecraft speedrunning API, enabling plain-language queries about players, matches, stats, and more.

Provides AI assistants with Titan SDK knowledge, verified spell IDs, and a Lua validator to generate combat rotations for any World of Warcraft class and specialization from a single prompt.

Enables MCP clients to commit to a 3D GitHub commit town, where each agent's commits build a progressively larger building, from cottage to skyscraper.

Enables AI agents to control a Minecraft bot inside a Java Edition world via MCP, providing tools for movement, building, mining, combat, farming, trading, inventory, and world perception.

Enables MCP clients to interact with a deterministic Black Sword Hack rules engine for tabletop RPG campaigns, including dice rolls and persistent campaign state management.

Three.js MCP server and Claude Code plugin: screenshot, play, test and profile the three.js pages your coding agent builds, in headless Chrome or Firefox.

Enables AI agents to connect to one or more running Roblox game clients to execute Lua code, decompile and search scripts, browse instances with CSS-like selectors, intercept and block remotes, drive GUIs, and capture screenshots through a local dashboard and bridge.

Manages the state of a chess game for LLMs/agents without suggesting moves, providing tools to create/reset game, add moves, get status, and check legality.

Enables Magic: The Gathering players to analyze deck lists using real Scryfall oracle text, detecting synergies and conflicts. Generates three viewable documents: an interactive synergy map, a detailed guide, and a printable cheat sheet.

Connects an MCP client to a running Serious Editor 2017 / Serious Sam Fusion instance through a local Lua bridge, enabling package and entry inspection, log reading, editor diagnostics, and previewed/undoable entity property edits on a captured selection.

Enables AI agents to play Arknights: Stronghold Protocol like a player over MCP by observing game state, querying game data, sending protocol actions, and running the game's client-side battle simulation. It bridges agents to a compatible game server through a read-only plugin and supports both direct MCP and Python SDK usage.

Provides MCP tools to interact with a running League of Legends client, including REST API calls, live event streaming, and DOM/JavaScript access.
