# Benefits of Local MCP Servers > Source: > Published: 2026-07-30 07:00:00+00:00 I developed a **local MCP server** in Rust that has some useful tool calls for often-needed commands. For example it can pull and compile a program, or load a blog post. It was interesting developing the MCP server, but I wanted to think about why an MCP server is **superior** to running the command lines directly. The LLM (and the chat window) is a **new interface** for **computer use**. With a prompt I can chain multiple function calls together, instead of having to enter the commands one after the other. And prompts have some level of error correction built-in: a typo can be automatically corrected. The **agentic layer** could also be used to allow voice commands to run the tools. So to restate: • Using an AI agent with an MCP server to run commonly-needed commands may increase ease of use. • Some development work is needed to get the MCP server working. Currently I am testing **Gemma 4 E4B** to handle the **agentic tool calls**. I can control a lot of things I do on the computer through a chat window in `llama-cpp` . I feel error correction, command chaining, and an improved UI (a browser instead of a terminal) are worthwhile.
