AI agents call reset_game_theme to permanently remove resources in DMCP — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool appears to delete or clear game theme configurations and potentially associated game state, which cannot be undone. While the description is terse and somewhat ambiguous ('Remove a game' could theoretically mean various things), the combination of 'reset' and 'remove' strongly suggests destructive data loss.
From the tool's definition Tool name 'reset_game_theme' combined with description 'Remove a game' indicates irreversible deletion or removal of game state data. The verb 'remove' paired with 'game' suggests data erasure rather than temporary modification.
Documented attack patterns abuse exactly the kind of access reset_game_theme gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and DMCP, and nothing reaches the server without passing your rules. This is the rule we recommend for reset_game_theme:
{
"version": "1",
"default": "deny",
"hide": [
"reset_game_theme"
]
}reset_game_theme disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Remove a game. It is categorised as a Destructive tool in the DMCP MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the D MCP server in PolicyLayer and add a rule for reset_game_theme: 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 DMCP. Nothing to install.
reset_game_theme is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the reset_game_theme 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 reset_game_theme. 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.
reset_game_theme is provided by the D MCP server (shawnrushefsky/dmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from DMCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
