WHAT IT DOES

What mw_deck does on ModWrench MCP Server

AI agents use mw_deck to create or update resources in ModWrench MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your ModWrench MCP Server environment.

Parameter	Type	Required	Description
`view`	string	—	Initial view. Default 'deck'.
`theme`	string	—	Initial theme: skyrim \| fallout \| lethal \| valheim. Default skyrim.

Parameters from the server's own tool schema.

RISK

Why mw_deck is rated Medium

An AI agent can call mw_deck faster than any human can review: one bad instruction and it creates or modifies resources in ModWrench MCP Server by the hundred, each call as confident as the last.

RECOMMENDED RULE

The rule that runs mw_deck safely

PolicyLayer is an MCP gateway: it sits between your AI agents and ModWrench MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For mw_deck, this is the rule to start with:

mw_deck Rate-limited

mw_deck stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

    }
  }
}

The button opens the PolicyLayer dashboard: create your workspace, connect ModWrench MCP Server, apply this rule, and every mw_deck call is checked against it from then on.

FAQ

Questions about mw_deck

What does the mw_deck tool do? +

Open the ModWrench deck: a themed, interactive MCP-UI surface (a ui:// resource) showing the active connectors and flagship games in four skins (Skyrim, Fallout Pip-Boy, Lethal Company, Valheim). Stateless — rendered fresh from the current catalog, holds nothing. Use when the user says "open the deck", "summon/show ModWrench", or wants a visual dashboard. Optional args set the initial theme and view. It is categorised as a Write tool in the ModWrench MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does mw_deck accept? +

mw_deck accepts 2 parameters: view, theme. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on mw_deck? +

Register the ModWrench MCP Server MCP server in PolicyLayer and add a rule for mw_deck: 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 ModWrench MCP Server. Nothing to install.

What risk level is mw_deck? +

mw_deck is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit mw_deck? +

Yes. Add a rate_limit block to the mw_deck 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.

How do I block mw_deck completely? +

Set action: deny in the PolicyLayer policy for mw_deck. 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.

What MCP server provides mw_deck? +

mw_deck is provided by the ModWrench MCP Server MCP server (@modwrench/cli). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
