NotePlan MCP Server

A Message Control Protocol (MCP) server that enables Claude Desktop to interact with NotePlan.co. This server provides seamless integration between Claude and your NotePlan notes, allowing you to query, search, create, and update notes directly from Claude conversations.

Features

• Read Notes: Get all notes, specific notes by ID, or notes from specific folders
• Search: Full-text search across all your notes
• Create Notes: Create new notes with titles, content, and folder organization
• Daily Notes: Create and manage daily notes with automatic date formatting
• Update Notes: Modify existing note titles and content
• Folder Organization: Organize and filter notes by folders

Installation

Option 1: Clone from GitHub

git clone https://github.com/bscott/noteplan-mcp.git
cd noteplan-mcp
npm install

Option 2: Install as NPM Package (Coming Soon)

npm install -g noteplan-mcp

Quick Start

1. Install dependencies:

   npm install
   

2. Build the project:

   npm run build
   

3. Test the server:

   npm start
   

   You should see: "NotePlan MCP server running on stdio"

4. Configure Claude Desktop (see detailed setup below)

Claude Desktop Configuration

To use this MCP server with Claude Desktop, add the following configuration to your Claude Desktop config file:

Step 1: Locate Your Config File

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json Linux: ~/.config/Claude/claude_desktop_config.json

Step 2: Add NotePlan MCP Server

Add this configuration to your claude_desktop_config.json:

{
  "mcpServers": {
    "noteplan": {
      "command": "node",
      "args": ["/absolute/path/to/noteplan-mcp/build/index.js"],
      "cwd": "/absolute/path/to/noteplan-mcp"
    }
  }
}

Important: Replace /absolute/path/to/noteplan-mcp with the actual path where you cloned this repository.

Step 3: Restart Claude Desktop

After saving the configuration, restart Claude Desktop completely for the changes to take effect.

Available Tools

Once configured, you can use these tools in Claude conversations:

Example Usage in Claude

Once set up, you can ask Claude things like:

• "Show me all my notes"
• "Search for notes containing 'project planning'"
• "Create a new note titled 'Meeting Notes' in the 'Work' folder"
• "Get today's daily note"
• "Update note ID 'note123' with new content"

Claude will automatically use the appropriate NotePlan MCP tools to fulfill these requests.

Development

Development Mode

npm run dev

This builds the TypeScript and starts the server with auto-restart on file changes using nodemon.

Building

npm run build

Compiles TypeScript to JavaScript in the build/ directory.

Testing

npm test

Linting

npm run lint

Troubleshooting

Claude Desktop Not Connecting

1. Check file paths: Ensure the paths in claude_desktop_config.json are absolute and correct
2. Check Node.js: Make sure Node.js is installed and accessible from your PATH
3. Check logs: Look for error messages in Claude Desktop's logs:
   • macOS: ~/Library/Logs/Claude/mcp-server-noteplan.log
   • Windows: %LOCALAPPDATA%\Claude\Logs\mcp-server-noteplan.log

Common Error Messages

"Cannot find module '/src/mcp-server.js'"

• The path in your config is incorrect. Use absolute paths, not relative ones.

"Server disconnected"

• Check that Node.js is installed and the server can start with npm start

Testing Your Setup

1. Test the server manually:

   cd /path/to/noteplan-mcp
   npm run build
   npm start
   

2. Use the MCP inspector for debugging:

   npm run inspector
   

3. Check Claude Desktop logs for connection status

4. Try a simple command in Claude: "Can you show me my notes?"

Configuration

Custom NotePlan Directory

By default, the server looks for NotePlan files in standard locations. If you use a custom directory, you can modify the noteService.js file to point to your NotePlan data directory.

Environment Variables

Currently, no environment variables are required, but future versions may support:

• NOTEPLAN_DATA_DIR: Custom NotePlan data directory
• MCP_LOG_LEVEL: Logging verbosity
