Manage character inventory. Operations: give (add items), take (remove items), equip (equip to slot), unequip (remove from slot), move (change container), list (show inventory), transfer (move between characters).
AI agents use manage_inventory to create or update resources in ChatRPG — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ChatRPG environment.
The tool creates and modifies inventory data (adding/removing/moving items, equipping/unequipping gear) but does not delete character data or irreversibly destroy information. All operations are reversible game mechanics typical of RPG systems. While 'take' removes items, inventory items are not permanently destroyed - they can be returned via 'give' or 'transfer'.
From the tool's definition Tool description explicitly states operations: 'give (add items), take (remove items), equip (equip to slot), unequip (remove from slot), move (change container), transfer (move between characters)' - all reversible modifications of game state.

Manage character inventory. Operations: give (add items), take (remove items), equip (equip to slot), unequip (remove from slot), move (change container), list (show inventory), transfer (move between characters). It is categorised as a Write tool in the ChatRPG MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the ChatRPG MCP server in PolicyLayer and add a rule for manage_inventory: 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 ChatRPG. Nothing to install.
manage_inventory is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the manage_inventory 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 manage_inventory. 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.
manage_inventory is provided by the ChatRPG MCP server (mnehmos/mnehmos.chatrpg.game). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
