Automatically apply an appropriate theme to a game based on its genre and setting. Call this when creating a new game to set up the visual style.
AI agents use auto_theme_game to create or update resources in DMCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your DMCP environment.
This tool creates or modifies game configuration data (theme settings) in a reversible manner. It does not delete data (ruling out Destructive), does not execute arbitrary code or external operations (ruling out Execute), does not move money (ruling out Financial), and only reads input parameters to decide what to write.
From the tool's definition The tool description states it will 'apply an appropriate theme to a game' which modifies game state. The sibling tool 'apply_theme_preset' and 'apply_game_theme_preset' corroborate that theme application is a write operation that changes stored game…
Documented attack patterns abuse exactly the kind of access auto_theme_game 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 auto_theme_game:
{
"version": "1",
"default": "deny",
"tools": {
"auto_theme_game": {
"limits": [
{
"counter": "auto_theme_game_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}auto_theme_game stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

Automatically apply an appropriate theme to a game based on its genre and setting. Call this when creating a new game to set up the visual style. It is categorised as a Write tool in the DMCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the D MCP server in PolicyLayer and add a rule for auto_theme_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 DMCP. Nothing to install.
auto_theme_game is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the auto_theme_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 auto_theme_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.
auto_theme_game 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.
