Description: MCP server for Joplin
Author: Jakub Frieb
Latest version: 1.1.0

# Joplin MCP Server

This is a Node.js implementation of an MCP (Model Context Protocol) server for Joplin.

## Installation

```bash
npm install
```

## Configuration

Create a `.env` file with the following variables:

```
JOPLIN_PORT=41184
JOPLIN_TOKEN=your_joplin_token
```

You can find your Joplin token in the Joplin desktop app under:
Tools > Options > Web Clipper

## Usage

Start the server:

```bash
npm start
```

You can also specify a custom environment file:

```bash
npm start -- --env-file .env.custom
```

Usage in Augment Code:
name: `joplin`
command: `node /path/to/your/mcp-joplin/index.js --env-file /path/to/your/mcp-joplin/.env`

Usage in mcp.json (cursor other tools)
```json
  "joplin":{
      "command":"node",
      "args":[
        "/path/to/your/mcp-joplin/index.js",
        "--env-file",
        "/path/to/your/mcp-joplin/.env"
      ]
  }
```



### Logging

The server logs all incoming commands and outgoing responses. Logs are stored in two places:

1. **Console output**: Basic information is displayed in the console
2. **Log files**: Detailed logs are saved in the `logs` directory with timestamps

You can adjust the log level by setting the `LOG_LEVEL` environment variable:

```bash
LOG_LEVEL=debug npm start
```

Available log levels (from most to least verbose):
- `debug`: All messages including detailed command and response data
- `info`: Standard operational messages (default)
- `warn`: Warnings and errors only
- `error`: Only error messages

## Available Tools

### list_notebooks

Retrieves the complete notebook hierarchy from Joplin.

```
# Example output:
Notebook 1 (id: "abc123")
  Subnotebook 1.1 (id: "def456")
  Subnotebook 1.2 (id: "ghi789")
Notebook 2 (id: "jkl012")
```

### search_notes

Searches for notes in Joplin and returns matching notebooks.

**Parameters:**
- `query`: The search query string

```
# Example usage:
search_notes query="project meeting"

# Example output:
Found 2 notes matching query: "project meeting"
NOTE: To read a notebook, use the notebook ID (not the note title)

- Note: "Weekly Project Meeting" (note_id: "abc123")
  Notebook: "Work" (notebook_id: "58a0a29f68bc4141b49c99f5d367638a")
  Updated: 3/15/2025, 10:30:45 AM
  Snippet: Notes from our weekly project meeting. Topics discussed: timeline, resources, next steps...

  To read this notebook: read_notebook notebook_id="72b1c45d89ef3212a67b98f4e5d23a1b"
```

> **Important**: Note the difference between note titles and IDs. When using the `read_notebook` command, you must use the notebook ID (a long alphanumeric string), not the notebook title.

### read_notebook

Reads the contents of a specific notebook.

**Parameters:**
- `notebook_id`: The ID of the notebook to read

```
# Example usage:
read_notebook notebook_id="58a0a29f68bc4141b49c99f5d367638a"

# Example output:
# Notebook: "Work" (notebook_id: "58a0a29f68bc4141b49c99f5d367638a")
Contains 3 notes:
NOTE: This is showing the contents of notebook "Work", not a specific note.

- ☐ Note: "Prepare presentation" (note_id: "jkl012")
  Updated: 3/13/2025, 9:20:33 AM

**Parameters:**
