THE RISK

Why delete_faction needs a policy

This tool permanently removes a faction from the game state without possibility of recovery within the game context. While the blast radius is limited to a single game session (not production data or financial systems), deleting a faction could destroy significant game progress, narrative elements, or player investments in that faction's storyline.

From the tool's definition Tool name is 'delete_faction' with description 'Delete a faction'. The word 'delete' indicates irreversible removal of game state data.

POLICY

How to control delete_faction

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 delete_faction:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_faction"
  ]
}

delete_faction disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register DMCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
