Get full race definition from loaded rulebooks.
AI agents call get_race_info to retrieve information from DM20 Protocol without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about character races from rulebooks—a straightforward read operation with no side effects. Even if race definitions are presented in a D&D context, the function performs only data lookup/query. There is no code execution, financial transaction, or data modification involved. Low severity because misuse would only expose harmless game mechanic reference information.
From the tool's definition Tool name 'get_race_info' and description 'Get full race definition from loaded rulebooks' indicate a retrieval operation that queries static rulebook data without modifying, executing, or deleting anything.
Attacks that exploit this kind of access
Get full race definition from loaded rulebooks. It is categorised as a Read tool in the DM20 Protocol MCP Server, which means it retrieves data without modifying state.
Register the DM20 Protocol MCP server in PolicyLayer and add a rule for get_race_info: 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 DM20 Protocol. Nothing to install.
get_race_info 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 get_race_info 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 get_race_info. 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.
get_race_info is provided by the DM20 Protocol MCP server (polloinfilzato/dm20-protocol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
