MarkIndex MCP server
by jackjin1997
Let your AI browse and search a folder of Markdown documents by structure, with line numbers for citations.
MarkIndex is a small helper that lets your AI read and search a folder full of Markdown documents, like manuals, policies, or notes. Instead of guessing chunks, it follows the document's own headings and sections. It is handy if you keep a large library of Markdown files and want your AI to find and quote the right parts.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you. An MCP server is a small helper program that gives your AI a new skill or a connection to something. MarkIndex is that helper for a folder of Markdown files. Once it is connected, your AI can look through those files and read the exact lines you need, when you ask.
What this MCP server does
You point MarkIndex at a folder of Markdown documents and it builds an index of their sections. When you ask your AI a question, the AI uses this helper to browse folders, look at a document's outline, or search by keywords. The helper then reads the original text with line numbers and hands it back. Your AI uses that to answer you and can show exactly where the answer came from.
What you can do with it
- Browse a folder to see what documents are inside
- Look at a document's section outline before reading it
- Read the original text of specific sections with line numbers
- Search across all documents by keywords, including Chinese and English
- Narrow a search to one folder or one document
- Get suggested next steps when a search finds nothing
Try asking your AI
- “What does the employee handbook say about resignation notice periods?”
- “Find the section about ISO-27001 audit steps in the policies folder.”
- “Show me the outline of the setup guide.”
- “Search for 离职 补偿 in my documents.”
What it gives back to you
You get back answers based on the real text of your documents, with line numbers so you can check the source. It can also return lists of folders and files, section outlines, and search results. Everything comes back in the chat, ready to read.
Before you start
What you need
- Node.js version 22.12 or newer
- A folder of Markdown files (.md or .markdown) on your computer
- An MCP client like Claude Code or Cursor
Good to know
The tools only read your indexed documents, but the text inside those documents is untrusted and could contain instructions aimed at your AI, so treat what comes back as information, not commands.
