Remote card content management using synchronous server-side scripting is provided. A method includes parsing a script configured to perform a card content management operation as a sequence of operations for a secure element based on receiving a request from a mobile device located remotely from a computer processor. The method also includes creating an execution context for the script to identify the sequence of operations in the script as non-flushing and flushing nodes. A flushing node is identified as an operation that sends a response to the request and expects a subsequent request from the mobile device for the secure element. The method further includes pausing execution of the script upon sending the response at the flushing node.
