AI agents invoke start_game to trigger actions in Minesweeper MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
The tool initiates game logic on an external Minesweeper server, which is an operation whose effects depend on arguments and cannot be undone without calling additional functions. This is characteristic of Execute rather than Write, as it triggers a discrete external action (game initialization) rather than modifying persistent data.
From the tool's definition Tool name and description indicate it 'Start[s] a new game of Minesweeper', which initializes a game state and triggers external game server operations based on provided arguments (difficulty, board size, etc.).
Documented attack patterns abuse exactly the kind of access start_game gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Minesweeper MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for start_game:
{
"version": "1",
"default": "deny",
"tools": {
"start_game": {
"limits": [
{
"counter": "start_game_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}start_game stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Start a new game of Minesweeper. It is categorised as a Execute tool in the Minesweeper MCP Server MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Minesweeper MCP Server MCP server in PolicyLayer and add a rule for start_game: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Minesweeper MCP Server. Nothing to install.
start_game is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the start_game rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for start_game. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
start_game is provided by the Minesweeper MCP Server MCP server (tonypan2/minesweeper-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
