Export all canvas elements as a JSON snapshot. Returns the raw JSON string.
AI agents call export_scene to retrieve information from tldraw MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and exports the current state of the canvas as JSON. It only retrieves data without modifying, deleting, or executing anything. The blast radius if misused is minimal — it only exposes canvas content.
From the tool's definition Export all canvas elements as a JSON snapshot. Returns the raw JSON string.
Attacks that exploit this kind of access
Export all canvas elements as a JSON snapshot. Returns the raw JSON string. It is categorised as a Read tool in the tldraw MCP Server MCP Server, which means it retrieves data without modifying state.
Register the tldraw MCP Server MCP server in PolicyLayer and add a rule for export_scene: 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 tldraw MCP Server. Nothing to install.
export_scene is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the export_scene 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 export_scene. 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.
export_scene is provided by the tldraw MCP Server MCP server (mihai-codes/tldraw-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
