Create a new image generation preset. Use different presets for different purposes: character portraits, location art, items with text, etc. Each preset can have its own tool, model, style, and workflow configuration.
AI agents use create_image_generation_preset 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 and stores configuration data (presets) for image generation within a game state management system. It is a Write operation because it creates new records/configurations that can be modified or deleted later. The severity is low because presets are non-critical metadata for RPG gameplay with no external side effects, financial impact, or irreversible data loss.
From the tool's definition Tool description states 'Create a new image generation preset' - the verb 'create' indicates data creation. The preset configuration (tool, model, style, workflow) is stored but reversible.
Documented attack patterns abuse exactly the kind of access create_image_generation_preset 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 create_image_generation_preset:
{
"version": "1",
"default": "deny",
"tools": {
"create_image_generation_preset": {
"limits": [
{
"counter": "create_image_generation_preset_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_image_generation_preset 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.

Create a new image generation preset. Use different presets for different purposes: character portraits, location art, items with text, etc. Each preset can have its own tool, model, style, and workflow configuration. 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 create_image_generation_preset: 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.
create_image_generation_preset 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 create_image_generation_preset 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 create_image_generation_preset. 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.
create_image_generation_preset 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.
