create_sticky · tldraw MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_sticky does on tldraw MCP Server

AI agents use create_sticky to create or update resources in tldraw MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your tldraw MCP Server environment.

WHY IT NEEDS A POLICY

Why create_sticky needs a policy

This tool creates new sticky note elements on a tldraw canvas. Creation of data is reversible (notes can be deleted via delete_element tool on the same server), so it falls under Write rather than Destructive. The blast radius is low because sticky notes on a diagram canvas carry minimal risk — they are ephemeral UI artifacts with no financial, security, or system-level consequences.

From the tool's definition Tool description states 'Create a sticky note on the canvas' and is 'Shorthand for create_element with type=note' — clearly a data creation operation.
