Code Assistant MCP server

Let your AI read, edit, and search files in your project, and run commands, all from chat.

Coding Developer tools For it and development Coding Agents

Code Assistant is a free, open-source coding helper that runs on your own computer. It gives your AI a set of basic tools for working with files and folders, so it can look at your code, make changes, and run commands when you ask. It is handy for developers and anyone who wants their AI to do real work inside a project folder, not just chat.

What is an MCP server? The 30-second version

On its own, your AI can only talk. An MCP server is a small helper program that gives your AI a new skill or a connection to an app or service. This one connects your AI to your project folder on your computer, so it can list files, read them, edit them, and run commands for you. When you ask your AI to do something with your code, it uses this helper behind the scenes.

What this MCP server does

You ask your AI something about your project, like to explain a file or fix a bug. The AI uses this helper to look at your files, read what is inside, and search for things. If you want a change, the helper can edit or write files, and it can run commands in your terminal. Then the AI tells you what it found or what it changed, right in the chat.

Flow diagram: you ask your AI “Read the main file and explain what it does”, on your own computer the Code Assistant MCP server works with your project files, and you get back answers in your chat.

“Add a comment at the top of README.md saying 'Work in progress'.”

What it gives back to you

You get answers in plain chat: lists of files, the text of a file, search results, or a short summary of what the AI found. If the AI made a change, it tells you which file it edited and what it changed. You can also see which tools ran and what they returned, so you always know what happened.
