## An Open-Source Service and CLI Tool Built for the MCP Protocol

As multi-model collaboration and agent ecosystems continue to take shape, AI models are no longer isolated silos operating independently. Instead, they must share context, synchronize states, and dynamically switch tasks and response sources based on user intent. In response to this need, *Contextus* was developed by the MATRIX AI Network as an open-source context management service.

*Contextus* is an open-source service system and command-line interface (CLI) tool designed specifically for the Model Context Protocol (MCP). Its goal is to simplify the configuration, routing, and shared management of MCP servers across different client applications.

&#x20;

Why Do We Need Contextus?

*Contextus* was designed to address the challenges faced by developers and users when interacting with multiple MCP-based model services, including:

* Manual configuration of model addresses for each client;
* Inability to share context across multiple models;
* Frequent local reconfiguration when switching services;
* Lack of a centralized tool for registration, activation, and state management.

*Contextus* is introduced as a semantic hub tool specifically designed to tackle these pain points.
