Large File MCP server

This is a small helper that lets your AI work with very large files, like multi-gigabyte log files or big data exports. Normally your AI can only see a little bit of a file at a time, and a giant file will not fit. This helper breaks the file into pieces and lets the AI look at just the parts you care about.

What this MCP server does

You ask your AI something about a big file, like finding errors in a log or reading a certain line. The AI passes your request to this helper. The helper opens the file on your computer, reads it in small pieces instead of all at once, and finds what you asked for. Then it sends the answer back to the AI, and the AI explains it to you in the chat. It never loads the whole file into memory, so even very large files are fine.

What you can do with it

• Read a specific chunk of a huge file
• Search for a word or pattern inside a large file
• Jump to a certain line and see the lines around it
• Get a summary of a file, like its size and line count
• Stream a very large file in pieces
• See the structure of a CSV or JSON file before reading it all

Try asking your AI

• “Find all ERROR messages in /var/log/app.log”
• “Show me line 1234 of /code/app.ts with some context around it”
• “What is the structure of /data/sales.csv?”
• “Read the first chunk of /var/log/system.log”

What it gives back to you

You get answers in the chat, like a list of matching lines with a few lines around each one, or a summary of the file with its size and line count. If you ask for a specific line, you see that line plus the lines before and after it. For a CSV or JSON file, you get a quick overview and a few sample rows or lines. Nothing is changed in your files; it only reads them.
