Allows for the management and monitoring of Syncthing file synchronization instances, providing capabilities to configure folders and devices, monitor system status and connectivity, and perform administrative actions such as rescanning folders or pausing synchronization.
Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@Syncthing MCP Server Check the sync status of my 'Photos' folder and list any errors."
That's it! The server will respond to your query, and you can continue using it as needed.
