autotask_create_ticket_attachment
Upload a file attachment to an existing Autotask ticket by providing the ticket ID, filename, and base64-encoded file content. The tool validates the 3 MB size limit before sending.
Instructions
Upload a file attachment to an existing ticket. The file content must be passed as a base64-encoded string in the data field (MCP is JSON-RPC, so binary bytes must be base64-encoded). Autotask enforces a 3 MB hard limit on ticket attachments; this tool validates the decoded size before calling the API and returns a clear error if the limit is exceeded. Example: { ticketId: 12345, title: "screenshot.png", data: "iVBORw0KGgoAAAANSUhEUgAA..." }
