Delete a character from the current campaign. Accepts character name, ID, or player name.
AI agents call delete_character to permanently remove resources in DM20 Protocol — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes data (a campaign character). Even in a game context, character deletion cannot be undone and represents permanent loss of game progress and player investment. The multiple ways to specify a character (name, ID, player name) increase the blast radius if an AI agent misidentifies which character to delete. Destructive is the most severe applicable category and takes precedence over Write.
From the tool's definition 'Delete a character from the current campaign' - the tool permanently removes character data with no indication of recovery or undo capability. Accepts multiple identifier types (character name, ID, player name) which increases risk of accidental deletion.
Attacks that exploit this kind of access
Delete a character from the current campaign. Accepts character name, ID, or player name. It is categorised as a Destructive tool in the DM20 Protocol MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the DM20 Protocol MCP server in PolicyLayer and add a rule for delete_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.
delete_character is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_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 delete_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.
delete_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.
