What move-data-type does on Mcp Dev
AI agents use move-data-type to create or update resources in Mcp Dev, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Mcp Dev environment.
Why move-data-type is rated Medium
The move operation modifies the position/location of a data type within the CMS hierarchy but does not delete or destroy data. It is reversible (can be moved back), distinguishing it from Destructive. It does not execute arbitrary code or trigger external operations, so it is not Execute. The action is a structural modification of CMS content, making Write the appropriate category.
From the tool's definition Tool name is 'move-data-type' with description 'Move a data type by Id'. Moving is a reversible modification operation in CMS contexts.
Attacks that exploit this kind of access
The rule that runs move-data-type safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Dev, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For move-data-type, this is the rule to start with:
move-data-type 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 Mcp Dev, apply this rule, and every move-data-type call is checked against it from then on.
Questions about move-data-type
Move a data type by Id. It is categorised as a Write tool in the Mcp Dev MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Mcp Dev MCP server in PolicyLayer and add a rule for move-data-type: 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 Mcp Dev. Nothing to install.
move-data-type 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 move-data-type 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 move-data-type. 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.
move-data-type is provided by the Mcp Dev MCP server (@umbraco-cms/mcp-dev). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
