Show HN: I built a MCP server so Claude can play Minesweeper

A developer created an MCP (Model Context Protocol) server that enables Claude to play Minesweeper through a standardized interface. Despite multiple attempts, Claude struggles with the game and frequently makes obvious mistakes, particularly on 9x9 boards, prompting questions about improving Claude's strategic reasoning through better prompting techniques.

Key Points

• •MCP (Model Context Protocol) server enables Claude to interact with Minesweeper through a standardized interface
• •Claude struggles with Minesweeper strategy despite having access to game state, making logical errors and failing to win on 9x9 boards
• •Current implementation reveals limitations in Claude's spatial reasoning and constraint satisfaction problem-solving abilities
• •Prompt engineering opportunities exist to improve Claude's performance: explicit strategy instructions, step-by-step reasoning requirements, or constraint-based guidance
• •Consider adding reasoning traces to prompts that force Claude to explain its logic before making moves (chain-of-thought prompting)
• •Implement feedback loops where Claude receives explicit information about move consequences and learns from failed attempts
• •Test whether providing Minesweeper heuristics (e.g., probability calculations, safe zone identification) in the system prompt improves win rates
• •MCP server architecture allows for iterative testing of different prompting strategies without code changes to the game logic
• •This demonstrates a practical use case for MCP: enabling AI agents to interact with external tools and games for capability evaluation
