Get a single canvas element by ID.
AI agents call get_element 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 retrieves information about a canvas element by its identifier. It performs a query operation that reads state without altering the canvas, creating or deleting elements, or triggering external effects. The verb 'Get' and the context of retrieving by ID are characteristic of Read category tools. Severity is low because retrieving diagram metadata poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'get_element' and description 'Get a single canvas element by ID' indicate data retrieval with no modification or side effects.

Register the tldraw MCP Server MCP server in PolicyLayer and add a rule for get_element: 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.
get_element 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_element 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_element. 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_element 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.
get_element is one line of tldraw MCP Server's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
