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.
๐ 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.
๐ 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
.mdfiles. - 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.
๐ฏ 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
๐ 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
๐ง How It Works
-
You run the CLI:
md-mcp --folder ~/notes --name "Notes"
-
md-mcp:
- Scans folder for
.mdfiles - Extracts metadata (frontmatter, descriptions)
- Updates Claude Desktop config
- Registers MCP server entry
- Scans folder for
-
In Claude Desktop:
- Restart Claude
- Server appears in MCP dropdown
- All markdown files available as resources
- Use search tools to find content
๐ 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"
}
๐ ๏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?"
๐ Requirements
- Python 3.8+
- mcp library
- Claude Desktop
๐ง 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?"
๐งช 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
๐ 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:
descriptionโ Used as resource description- Other fields stored in
frontmatterdict
If no frontmatter, first paragraph is used as description.
๐ง Roadmap
- v0.3: Smart chunking for large files
- v0.4: Semantic search with embeddings
- v1.0: Use web UI for all operations
๐ Troubleshooting
"Server not showing in Claude Desktop"
-
Check config was updated:
md-mcp --status -
Verify file exists:
# Windows type %APPDATA%\Claude\claude_desktop_config.json # Mac/Linux cat ~/.config/Claude/claude_desktop_config.json
-
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
