Retrieve complete information about the current diagram scene.\n\n
AI agents call get_scene to retrieve information from Excalidraw MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns scene data from an existing Excalidraw diagram without creating, modifying, deleting, or executing any operations. It is a read-only operation with no side effects, matching the Read category definition. The scope is limited to diagram metadata, presenting minimal security risk.
From the tool's definition Tool name 'get_scene' and description 'Retrieve complete information about the current diagram scene' indicate data retrieval with no modification capability.
Documented attack patterns abuse exactly the kind of access get_scene gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Excalidraw MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_scene:
{
"version": "1",
"default": "deny",
"tools": {
"get_scene": {}
}
}get_scene is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieve complete information about the current diagram scene.\n\n. It is categorised as a Read tool in the Excalidraw MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Excalidraw MCP Server MCP server in PolicyLayer and add a rule for get_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 Excalidraw MCP Server. Nothing to install.
get_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 get_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 get_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.
get_scene is provided by the Excalidraw MCP Server MCP server (scofieldfree/excalidraw-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
