agent-tool MCP server

agent-tool is a helper program that plugs into your AI coding assistant and gives it a bigger, safer toolbox. It is made for people who work with code every day and want the AI to edit files without breaking tabs, old encodings, or line endings. If you have ever seen your AI turn a tidy file into a mess, this is for you.

What this MCP server does

You ask your AI to do something, like fix a line in a file or check whether a server is reachable. The AI sends that request to agent-tool, which runs on your computer. agent-tool opens the file, keeps its original tabs and encoding, makes the change, and hands the result back. You see the answer or the change in your chat window, and nothing else on your machine is touched unless you asked for it.

What you can do with it

• Edit files while keeping tabs, spaces, and the original encoding
• Read files with line numbers and clear notes when the file is long
• Search inside files with regex and skip folders like .gitignore
• Run commands on a remote server over SSH
• Query MySQL or Redis and see the results as a table
• Check if a port is open, look up DNS, or inspect a TLS certificate
• Copy, rename, compress, and back up files safely

Try asking your AI

• “Fix the indentation in src/main.py so it matches the rest of the file”
• “Search the project for TODO comments and show me the first 20”
• “Connect to my server over SSH and show the last 50 lines of the app log”
• “Run this SQL query on my local MySQL and show the results”

What it gives back to you

You get back plain answers in the chat: file contents with line numbers, search results grouped by file, command output, or a table of database rows. When it edits a file, it tells you what changed and keeps the original style. Long results are cut off with a clear note and a way to ask for the next part.

Who it's for

Developers and anyone who uses an AI coding assistant on real projects with strict formatting, old encodings, or remote servers.
