What You Can Do

This MCP server provides 21 optimized tools for comprehensive Joplin integration:

Note Management

• Find & Search: find_notes, find_notes_with_tag, find_notes_in_notebook, get_all_notes
• CRUD Operations: get_note, get_links, create_note, update_note, delete_note

Notebook Management

• Organize: list_notebooks, create_notebook, update_notebook, delete_notebook

Tag Management

• Categorize: list_tags, create_tag, update_tag, delete_tag, get_tags_by_note
• Link: tag_note, untag_note

System

• Health: ping_joplin

Quick Start

1. Install the Package

pip install joplin-mcp

2. Configure Joplin

1. Open Joplin Desktop → Tools → Options → Web Clipper
2. Enable the Web Clipper service
3. Copy the Authorization token

3. Run Setup Script

joplin-mcp-install

This interactive script will:

• Configure your Joplin API token
• Set tool permissions (Create/Update/Delete)
• Set up Claude Desktop automatically
• Test the connection

4. Choose Your AI Client

Option A: Claude Desktop

After running the setup script, restart Claude Desktop and you're ready to go!

"List my notebooks" or "Create a note about today's meeting"

Option B: OllMCP (Local AI Models)

If Claude Desktop was configured above, you can run the following to detect joplin-mcp automatically by OllMCP (Ollama served agents).

# Install ollmcp
pip install ollmcp

# Run with auto-discovery and your preferred Ollama model, such as:
ollmcp --auto-discovery --model qwen3:4b

Example Usage

Once configured, you can ask your AI assistant:

• "List all my notebooks" - See your Joplin organization
• "Find notes about Python programming" - Search your knowledge base
• "Create a meeting note for today's standup" - Quick note creation
• "Tag my recent AI notes as 'important'" - Organize with tags
• "Show me my todos" - Find task items with find_notes(task=True)

Tool Permissions

The setup script offers 3 security levels:

• Read (always enabled): Browse and search your notes safely
• Write (optional): Create new notes, notebooks, and tags
• Update (optional): Modify existing content
• Delete (optional): Remove content permanently

Choose the level that matches your comfort and use case.

Advanced Configuration

Alternative Installation (Development)

For developers or users who want the latest features:

macOS/Linux:

git clone https://github.com/alondmnt/joplin-mcp.git
cd joplin-mcp
./install.sh

Windows:

git clone https://github.com/alondmnt/joplin-mcp.git
cd joplin-mcp
install.bat

Manual Configuration

If you prefer manual setup or the script doesn't work:

1. Create Configuration File

Create joplin-mcp.json in your project directory:

{
  "token": "your_api_token_here",
  "host": "localhost", 
  "port": 41184,
  "timeout": 30,
  "verify_ssl": false
}

2. Claude Desktop Configuration

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "joplin": {
      "command": "joplin-mcp-server",
      "env": {
        "JOPLIN_TOKEN": "your_token_here"
      }
    }
  }
}

3. OllMCP Manual Configuration

# Set environment variable
export JOPLIN_TOKEN="your_token_here"

# Run with manual server configuration
ollmcp --server "joplin:joplin-mcp-server" --model qwen3:4b

Tool Permission Configuration

Fine-tune which operations the AI can perform by editing your config:

{
  "tools": {
    "create_note": true,
    "update_note": true, 
    "delete_note": false,
    "create_notebook": true,
    "delete_notebook": false,
    "create_tag": true,
    "update_tag": false,
    "delete_tag": false
  }
}

Environment Variables

Alternative to JSON configuration:

export JOPLIN_TOKEN="your_api_token_here"
export JOPLIN_HOST="localhost"
export JOPLIN_PORT="41184"
export JOPLIN_TIMEOUT="30"

HTTP Transport Support

The server supports both STDIO and HTTP transports:

# STDIO (default)
joplin-mcp-server

# HTTP transport 
python run_fastmcp_server.py --transport http --port 8000

Claude Desktop HTTP config

{
  "mcpServers": {
    "joplin": {
      "transport": "http",
      "url": "http://localhost:8000/mcp"
    }
  }
