Instantly expose markdown folders as MCP servers for Claude Desktop

Project description

md-mcp

Transform from Prompt Engineering to Context Engineering.

A lightweight Python library that instantly exposes your local markdown documentation, notes, and knowledge bases to any AI tool that supports the Model Context Protocol (MCP) โ€“ including Claude Desktop.

No embeddings, no preprocessing, and no uploading. Your files stay safely on your local machine, and any real-time updates are instantly reflected in your AI's context.

md-mcp Web Interface


๐Ÿš€ Quick Start

1. Install

Option A: Install from pypi

pip install md-mcp

Option B: Install from source code

pip install -e .

2. Launch the Web UI (Recommended)

The easiest way to manage your markdown servers is through the visual dashboard:

md-mcp --web

Just point at a folder and go!

3. Or use the CLI

If you prefer the command line:

# Expose a folder of markdown files
md-mcp --folder ~/Documents/notes --name "My Notes"

# That's it! Restart Claude Desktop and it's available.

๐Ÿ“‹ Features

  • Context Engineering: Feed your AI assistant exactly the right local context to get better answers, eliminating the need to endlessly prompt.
  • Universal MCP Support: Works natively with Claude Desktop and any other AI tool or agent that supports the Model Context Protocol.
  • Local & Secure First: Your files never leave your machine. No cloud uploads, no third-party APIs parsing your sensitive notes.
  • Real-time Sync: Edit your markdown files and the MCP server picks up the changes instantly. No need to regenerate embeddings or re-index.
  • Zero Configuration: Just point at a folder and go.
  • Auto-Discovery: Recursively finds all .md files.
  • Metadata Extraction: Parses YAML frontmatter and first paragraphs for rich resource descriptions.
  • Search Support: Built-in search across all files to quickly find the needle in the haystack.
  • Web Interface: Easy-to-use visual dashboard for non-technical users to manage multiple knowledge bases.

๐ŸŽฏ Use Cases

1. Personal Knowledge Base

md-mcp --folder ~/obsidian-vault --name "Obsidian"

โ†’ Claude can now read your entire Obsidian vault

2. Project Documentation

md-mcp --folder ~/code/myproject/docs --name "Project Docs"

โ†’ Claude has full context on your project

3. Research Papers

md-mcp --folder ~/research/papers-md --name "Research"

โ†’ Claude can reference your research notes


๐Ÿ“– Advanced Usage commands

Web Interface (easiest way to use)

md-mcp --web
# Launches a dashboard to manage all your markdown servers

Add a Markdown Folder

# With explicit name
md-mcp --folder /path/to/docs --name "My Docs"

# Auto-name from folder
md-mcp --folder ~/notes
# Creates server named "notes"

# Alias: --add
md-mcp --add ~/work-docs --name "Work"

Scan Before Adding (Dry Run)

md-mcp --folder ~/notes --scan
# Shows what files would be exposed

List Configured Servers

md-mcp --list
# Shows all md-mcp servers

Show Configuration Status

md-mcp --status
# Shows Claude config path and all servers

Remove a Server

md-mcp --remove "My Docs"

Interactive Mode

md-mcp
# Prompts for folder path

๐Ÿ”ง How It Works

  1. You run the CLI:

    md-mcp --folder ~/notes --name "Notes"
    
  2. md-mcp:

    • Scans folder for .md files
    • Extracts metadata (frontmatter, descriptions)
    • Updates Claude Desktop config
    • Registers MCP server entry
  3. In Claude Desktop:

    • Restart Claude
    • Server appears in MCP dropdown
    • All markdown files available as resources
    • Use search tools to find content

๐Ÿ“‚ What Gets Exposed

Each markdown file becomes an MCP Resource:

{
  "uri": "md://notes/project-plan.md",
  "name": "Project Plan",
  "description": "Auto-extracted from frontmatter or first paragraph",
  "mimeType": "text/markdown"
}

๐Ÿ› ๏ธ MCP Tools

md-mcp provides two tools to Claude:

1. search_markdown

Search across all markdown files by content or filename.

Usage in Claude:

"Search my notes for 'docker compose'"

2. list_files

List all available markdown files.

Usage in Claude:

"What markdown files do I have about Python?"


๐Ÿ“‹ Requirements

  • Python 3.8+
  • mcp library
  • Claude Desktop

๐Ÿ”ง Configuration

Claude Desktop Config Location (Automatic)

Windows: %APPDATA%\Claude\claude_desktop_config.json

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Linux: ~/.config/Claude/claude_desktop_config.json

Antigravity Config Location (Manual)

Windows: %USERPROFILE%\.gemini\antigravity\mcp_config.json

Add your config and run Developer: Reload Window from the Command Palette (Ctrl+Shift+P).

Config Entry Format

{
  "mcpServers": {
    "my-notes": {
      "command": "C:\\Python\\python.exe",
      "args": [
        "-m", "md_mcp.server_runner",
        "--folder", "C:\\Users\\Yang\\notes",
        "--name", "my-notes"
      ]
    }
  }
}

VS Code MCP Config (Manual)

For workspace-level tools, use a file at .vscode/mcp.json. See official VS Code MCP documentation.

[!IMPORTANT] For workspace configs, the top-level key is "servers", not "mcpServers".

Example .vscode/mcp.json:

{
  "servers": {
    "my-notes": {
      "command": "C:\\Python\\python.exe",
      "args": [
        "-m", "md_mcp.server_runner",
        "--folder", "C:\\Users\\Yang\\notes",
        "--name", "my-notes"
      ]
    }
  }
}

Sample Prompts to Test

Once configured, try these prompts with your AI assistant:

  • "Search my-notes for 'Docker'"
  • "List markdown files in my-notes"
  • "What do my notes say about the system architecture?" List markdown files

๐Ÿงช Testing

Test the Scanner

from md_mcp.scanner import MarkdownScanner

scanner = MarkdownScanner("~/notes")
files = scanner.scan()

for f in files:
    print(f"{f.name}: {f.description}")

Test the Server Locally

# Run server directly (stdio mode)
python -m md_mcp.server_runner --folder ~/notes --name test

# Server listens on stdin/stdout for MCP protocol

๐Ÿ“ Markdown Frontmatter Support

md-mcp extracts metadata from YAML frontmatter:

---
title: My Document
description: A brief overview of the document
tags: [project, planning]
---

# Content starts here

Extracted fields:

  • description โ†’ Used as resource description
  • Other fields stored in frontmatter dict

If no frontmatter, first paragraph is used as description.


๐Ÿšง Roadmap

  • v0.3: Smart chunking for large files
  • v0.4: Semantic search with embeddings
  • v1.0: Use web UI for all operations

๐Ÿ› Troubleshooting

"Server not showing in Claude Desktop"

  1. Check config was updated:

    md-mcp --status
    
  2. Verify file exists:

    # Windows
    type %APPDATA%\Claude\claude_desktop_config.json
    
    # Mac/Linux
    cat ~/.config/Claude/claude_desktop_config.json
    
  3. Restart Claude Desktop completely

"No files found"

# Check what scanner finds
md-mcp --folder ~/notes --scan

"Permission denied"

Make sure the folder is readable:

# Check permissions
ls -la ~/notes
