Create a new resource (currency, reputation, counter, etc.)
AI agents use create_resource 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.
The tool creates new game entities (currency, reputation, counter) within an RPG game state management context. This is a Write operation because it modifies data reversibly—new resources can be edited, deleted, or reset without permanent loss.
From the tool's definition Tool description states it 'Create[s] a new resource (currency, reputation, counter, etc.)' — this is a reversible creation operation that modifies game state without destructive or irreversible effects.
Documented attack patterns abuse exactly the kind of access create_resource 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_resource:
{
"version": "1",
"default": "deny",
"tools": {
"create_resource": {
"limits": [
{
"counter": "create_resource_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_resource 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.
Free to start. No card required.
Create a new resource (currency, reputation, counter, etc.). 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_resource: 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_resource 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_resource 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_resource. 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_resource 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.
