What createWhiteboard does on Stable Baseline
AI agents use createWhiteboard 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 |
|---|---|---|---|
title | string | Yes | REQUIRED. A clear, descriptive board name (e.g. 'Q3 GTM plan'). Programmatic boards must be titled — blank/'Untitled' titles are rejected. |
folderId | string | — | Optional folder to file the whiteboard under. |
projectId | string | Yes |
Parameters from the server's own tool schema.
Why createWhiteboard is rated Medium
An AI agent can call createWhiteboard faster than any human can review: one bad instruction and it creates or modifies resources in Stable Baseline by the hundred, each call as confident as the last.
Attacks that exploit this kind of access
The rule that runs createWhiteboard 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 createWhiteboard, this is the rule to start with:
createWhiteboard 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 Stable Baseline, apply this rule, and every createWhiteboard call is checked against it from then on.
Questions about createWhiteboard
Create a whiteboard: an infinite freeform canvas. A whiteboard is a hidden document (it won't appear in listDocuments) that hosts a single freeform canvas, and opens in the immersive whiteboard editor in the app. Returns documentId + diagramId. Author shapes afterwards with addWhiteboardElements (high-level specs) or updateWhiteboardScene. For anything beyond a blank board, call getWhiteboardGuide first to plan the layout (stencils vs architecture icons vs code/BPMN diagrams vs plain shapes), and render with getWhiteboardImage to verify as you go. 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.
createWhiteboard accepts 3 parameters: title, folderId, projectId. Required: title, projectId. The full parameter table on this page comes from the server's own tool schema.
Register the Stable Baseline MCP server in PolicyLayer and add a rule for createWhiteboard: 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.
createWhiteboard 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 createWhiteboard 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 createWhiteboard. 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.
createWhiteboard 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.
