AI agents call character_wizard to retrieve information from Narrarium without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only returns a pre-defined checklist to guide the agent in gathering information. It does not create, modify, or delete any data, making it a pure read/retrieval operation with minimal risk.
From the tool's definition "Return the Narrarium character creation checklist" — the tool retrieves/returns a checklist template; no data is created or modified.
Attacks that exploit this kind of access

Register the Narrarium MCP server in PolicyLayer and add a rule for character_wizard: 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 Narrarium. Nothing to install.
character_wizard is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the character_wizard 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 character_wizard. 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.
