Get detailed character information. Accepts character name, ID, or player name.
AI agents call get_character 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 character data from what appears to be a game management system. It accepts identifiers (character name, ID, or player name) and returns information without modifying any state. The blast radius of misuse is minimal—an agent could retrieve character sheets it shouldn't access, but cannot alter game state, execute commands, or cause irreversible damage. This is a straightforward Read operation.
From the tool's definition Tool name 'get_character' and description 'Get detailed character information' indicate data retrieval with no modification or side effects.
Attacks that exploit this kind of access
Get detailed character information. Accepts character name, ID, or player name. 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_character: 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_character 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_character 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_character. 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_character 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.
