AI agents invoke click 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.
This tool executes an action on an external game server (a click/reveal operation on the Minesweeper board). It is not a simple read, it triggers a state change in the game. Since it's confined to a game context with no financial, destructive, or broadly impactful consequences, severity is low.
From the tool's definition 'Click at a cell on the Minesweeper board' — triggers an external operation (a click action) on the Minesweeper game server
Documented attack patterns abuse exactly the kind of access click 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 click:
{
"version": "1",
"default": "deny",
"tools": {
"click": {
"limits": [
{
"counter": "click_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}click 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.

Click at a cell on the Minesweeper board. 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 click: 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.
click 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 click 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 click. 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.
click 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.
