AI agents call open_editor to retrieve information from Flowchart MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool simply returns a URL for the editor interface. It reads/fetches information (a URL) without creating, modifying, or deleting any data. The actual editing happens separately through other tools.
From the tool's definition 'Get the URL to open the visual flowchart editor in the browser' — retrieves a URL, no data modification
