MCP Linux Common Utility Server

What is MCP Linux Common Utility Server?

The Model Context Protocol (MCP) Linux Common Utility (LCU) Server is a Python‑based server that exposes a wide range of Linux system operations — including CPU, memory, processes, filesystem, hardware, network, monitoring, and logs — as MCP tools and resources. It is built for developers and system administrators who want to interact with a Linux host programmatically through any MCP client.

How to use MCP Linux Common Utility Server?

Install the package from source (requires Python 3.10+ and a Linux OS). Start the server with the mcp-lcu-server command, choosing the transport type (stdio, sse, or both) and optionally a custom port/host. Behaviour such as allowed paths, process kill permissions, and monitoring intervals are set via a YAML configuration file (default locations: ./config.yaml, ./config/config.yaml, /etc/mcp-lcu-server/config.yaml, ~/.config/mcp-lcu-server/config.yaml).
