Sparetext MCP

An official MCP server provided by Sparetext that enables AI agents to send and read real SMS messages from the user's own Android or iPhone device. It supports tools for sending single or batch messages, managing drafts, retrieving conversations, and handling campaign launches, operating without per-message fees by utilizing the device's native carrier plan.
