I built a MCP server so Claude can play Minesweeper
Hi! I build an MCP server that allows clients to play Minesweeper. It turns out that Claude is not very good at it (makes obvious mistakes, hasn't won a single game on a 9x9 board after many attempts). I am curious how I can prompt Claude to do better?
I built a MCP server so Claude can play Minesweeper launched on March 20, 2025 with 123 votes, #365 of 7,215 launches that month and more than 95% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This is an MCP server that enables Claude to play Minesweeper through an integrated game interface. The tool is designed for developers and AI enthusiasts interested in testing Claude's logical reasoning and decision-making abilities. The creator notes that Claude currently struggles with the game, frequently makes obvious errors, and has yet to win on a 9x9 board despite multiple attempts, raising questions about optimal prompting strategies for improving AI performance on tactical puzzle tasks.

For example, here is how to add the tool to Claude Desktop on Windows's claude_desktop_config.json ( locating the file ), assuming you cloned the repo at C:\path\to\repo\minesweeper-mcp-server : { "mcpServers" : { "mcp-server" : { "command" : " node " , "args" : [ " C: \\ path \\ to \\ repo \\ minesweeper-mcp-server \\ build \\ index.js " ], "env" : { "DEBUG" : " * " } } } } Claude…from github.com

I made a live multiplayer Minesweeper game2025 · minesweeperpro.com · ▲242Hi everyone! For several months now I've been stuck on the idea of a Minesweeper game that isn't just single player. This is what I came up with: • Live games allowing several people to play at the same time • Scoring system rewarding correct moves • Grid size, mines count, and players count set to make games as balanced as possible
Playwright Skill for Claude Code – Less context than playwright-MCP2025 · github.com · ▲189I got tired of playwright-mcp eating through Claude's 200K token limit, so I built this using the new Claude Skills system. Built it with Claude Code itself. Instead of sending accessibility tree snapshots on every action, Claude just writes Playwright code and runs it. You get back screenshots and console output. That's it. 314 lines of instructions vs a persistent MCP server. Full API docs only load if Claude needs them. Same browser automation, way less overhead. Works as a Claude Code plugin or manual install. Token limit issue:…
The classic Minesweeper on an irregular grid2024 · polyreplay.com · ▲293I'm experimenting game mechanics that are usually seen on a typical grid, but transposed on an irregular one. This is a first game based on Minesweeper. The changes an irregular grid brings are that cells don't all have 8 neighbors. Some can have less, some can have more. So when you try and deduce if a tile has a mine, you have to pay closer attention at the number clues and which tiles neighbors it. My intention is to make a very classic game a bit more challenging & fun. I've also released a first version of Checkers/Draughts, and plan to test similar variants for Chess, Othello and…
AI BrowserNov 2025 · aibrowser.surf · ▲143Hey HN! I built Browser AI after getting frustrated with the official Playwright MCP server in Claude Code. If you've used it, you know the pain: - 20+ separate tools that Claude has to juggle (click, fill, navigate, wait_for_selector, etc.) - Context window explosions from verbose screenshot data and DOM snapshots - Constant tool selection errors where Claude picks the wrong tool or forgets parameters Browser AI wraps Playwright MCP with a single natural language interface. Instead of Claude managing dozens of tools, you get one: browser_ai.execute. Just tell it what you want in plain…
I made Claude play Minecraft using Agent SDKJan 2026 · github.com · ▲5This weekend I built a Minecraft bot for a server I play on. It uses the Agent SDK for the main loop and a bunch of custom MCP tools. Some highlights: * The bot is an active participant in the in-game chat, enabling all players to interact with it. * Tools for interacting with containers, crafting, trading with villagers and various other things. * Memory system which the agent uses to keep track of in-game events, interactions with players etc. * Screenshot tool which lets Claude use its vision modality to look around (not very useful, but fun). * Tooling for interacting with plugins…
