FoxBox – Native MCP support for sending and receiving SMS from AI agents

FoxBox has become the first SMS hardware gateway to implement the Model Context Protocol (MCP), enabling native AI and automation interoperability for on-premise SMS infrastructure. The MCP integration allows AI agents and LLMs to send and receive SMS messages directly, without custom integrations or cloud dependency, supporting use cases like multi-agent orchestration and automated alerts.

FOXBOX is proud to be the first SMS hardware gateway in the world to implement MCP Model Context Protocol , bringing native AI and automation interoperability to on-premise SMS infrastructure. With MCP, FOXBOX is no longer just an SMS gateway: it becomes a standardized, AI-ready messaging tool , directly accessible by intelligent systems, agents and automation platforms. Model Context Protocol MCP is an open, standardized protocol that allows software systems and AI models to: MCP enables AI agents and automation platforms to interact with external systems like FOXBOX in a safe, deterministic and machine-readable way . FoxBox is AI Agent Ready SMS API Until today, SMS gateways exposed APIs designed mainly for human developers . FOXBOX changes this paradigm. By implementing MCP, FOXBOX becomes: Directly usable by LLMs and agents SMS functions exposed as discoverable tools Easily orchestrated inside larger workflows No cloud dependency FOXBOX exposes an MCP endpoint using JSON-RPC 2.0 , fully compatible with MCP clients. Send outbound SMS messages via FOXBOX. Supports: Retrieve incoming SMS messages. Supports filters: An AI agent can: No custom SMS integration is required. Example use cases An LLM can: All without exposing FOXBOX directly to the internet. FOXBOX can be used as an action endpoint inside automation platforms: MCP allows these systems to discover SMS capabilities automatically , instead of hard-coding integrations. Organizations can run: …and still use SMS as an external communication channel , without cloud SMS providers. FOXBOX remains fully on-premise , while MCP provides a modern integration layer. Multi-Agent Orchestration In advanced setups: MCP makes FOXBOX a first-class tool in multi-agent systems. This is not a wrapper.
