WHAT IT DOES

What duplicateWhiteboardElements does on Stable Baseline

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

Parameter	Type	Required	Description
`dx`	number	—	Horizontal offset for the copy (default 40). Use the element width + a gap to place copies side by side.
`dy`	number	—	Vertical offset for the copy (default 40).
`ids`	array	—	Element ids to copy. Each id's full group + any bound text are auto-included. Use this and/or groupId.
`group`	boolean	—	Group the copy into one new unit so it moves/duplicates together (default true).
`groupId`	string	—	Copy EVERY element in this group as one unit — e.g. a placed stencil's `groupId` returned by addWhiteboardElements.
`documentId`	string	Yes	The whiteboard's documentId.
`includeGroupPeers`	boolean	—	Auto-include the full group of any id you pass (default true).

Parameters from the server's own tool schema.

RISK

Why duplicateWhiteboardElements is rated Medium

This tool creates new whiteboard elements by duplicating existing ones — a reversible write/create operation. It does not execute code, delete data, or involve financial transactions. The blast radius is medium since misuse could clutter or corrupt a shared whiteboard, but changes are reversible.

From the tool's definition Clones the given elements (plus their group peers + bound text/labels) with FRESH ids, offsets the copy by dx/dy, and by default groups it into ONE new unit

RECOMMENDED RULE

The rule that runs duplicateWhiteboardElements safely

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

duplicateWhiteboardElements Rate-limited

duplicateWhiteboardElements 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.

LIMIT THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Stable Baseline, apply this rule, and every duplicateWhiteboardElements call is checked against it from then on.

FAQ

Questions about duplicateWhiteboardElements

What does the duplicateWhiteboardElements tool do? +

Copy-paste existing whiteboard elements — the MCP equivalent of selecting a group and pressing Ctrl/Cmd+D. Clones the given elements (plus their group peers + bound text/labels) with FRESH ids, offsets the copy by dx/dy, and by default groups it into ONE new unit so it moves together. Use it to build something once (a labelled stencil frame, a kanban card, a UML class) then stamp out consistent repeats fast — then retext/recolour each copy by its new id (via the returned idMap) with updateWhiteboardScene. Pass groupId to copy a whole group as a unit (e.g. a placed stencil's groupId from its placement result) and/or ids for specific elements. Internal references (group membership, bound text containerId, arrow start/end bindings) are remapped within the copied set; a binding to an element you did NOT copy is dropped. Returns { duplicated, idMap (old id → new id), groupId (the copy's new unit group), elementCount }. Render with getWhiteboardImage afterwards to verify. It is categorised as a Write tool in the Stable Baseline MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

What parameters does duplicateWhiteboardElements accept? +

duplicateWhiteboardElements accepts 7 parameters: dx, dy, ids, group, groupId, documentId, includeGroupPeers. Required: documentId. The full parameter table on this page comes from the server's own tool schema.

How do I enforce a policy on duplicateWhiteboardElements? +

Register the Stable Baseline MCP server in PolicyLayer and add a rule for duplicateWhiteboardElements: 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 Stable Baseline. Nothing to install.

What risk level is duplicateWhiteboardElements? +

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

Can I rate-limit duplicateWhiteboardElements? +

Yes. Add a rate_limit block to the duplicateWhiteboardElements 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 duplicateWhiteboardElements completely? +

Set action: deny in the PolicyLayer policy for duplicateWhiteboardElements. 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 duplicateWhiteboardElements? +

duplicateWhiteboardElements is provided by the Stable Baseline MCP server (https://api.stablebaseline.io/functions/v1/cloud-serve/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
