What is Nextcloud Mcp Server

Nextcloud MCP Server is a server that enables Large Language Models (LLMs) such as OpenAI’s GPT, Google’s Gemini, or Anthropic’s Claude to interact with a Nextcloud instance, facilitating automation of various actions within Nextcloud, starting with the Notes API.

Use cases

Use cases include automating note-taking processes, integrating LLMs for enhanced note management, and facilitating collaborative projects where notes need to be shared and updated frequently.

How to use

To use Nextcloud MCP Server, clone the repository, install the required packages, and configure your Nextcloud credentials in a .env file. You can run the server locally or use the pre-built Docker image.

Key features

Key features include the ability to create, update, and delete notes via the Nextcloud Notes API. It also provides access to specific notes, all notes, note settings, and server capabilities.

Where to use

Nextcloud MCP Server can be used in any environment where Nextcloud is deployed, particularly in collaborative workspaces, educational institutions, and organizations that require efficient note management.

Nextcloud MCP Server

The Nextcloud MCP (Model Context Protocol) server allows Large Language Models (LLMs) like OpenAI’s GPT, Google’s Gemini, or Anthropic’s Claude to interact with your Nextcloud instance. This enables automation of various Nextcloud actions, starting with the Notes API.

Features

Currently, the server primarily interacts with the Nextcloud Notes API, providing tools and resources to manage notes.

Available Tools

• nc_notes_create_note: Create a new note.
• nc_notes_update_note: Update an existing note by ID.
• nc_notes_append_content: Append content to an existing note with a clear separator.
• nc_notes_delete_note: Delete a note by ID.
• nc_notes_search_notes: Search notes by title or content.
• nc_get_note: Get a specific note by ID.

Available Resources

• notes://{note_id}: Access a specific note by its ID.
• notes://all: Access all notes.
• notes://settings: Access note settings.
• nc://capabilities: Access Nextcloud server capabilities.
• nc://Notes/{note_id}/attachments/{attachment_filename}: Access attachments for notes.

Note Attachments

This server supports adding and retrieving note attachments via WebDAV. Please note the following behavior regarding attachments:

• When a note is deleted, its attachments remain in the system. This matches the behavior of the official Nextcloud Notes app.
• Orphaned attachments (attachments whose parent notes have been deleted) may accumulate over time.
• WebDAV permissions must be properly configured for attachment operations to work correctly.

Installation

Prerequisites

• Python 3.8+
• Access to a Nextcloud instance

Local Installation

1. Clone the repository (if running from source):

   git clone https://github.com/cbcoutinho/nextcloud-mcp-server.git
   cd nextcloud-mcp-server
   

2. Install the package (if running as a library):

   poetry install
   

Docker

A pre-built Docker image is available: ghcr.io/cbcoutinho/nextcloud-mcp-server

Configuration

The server requires credentials to connect to your Nextcloud instance. Create a file named .env (or any name you prefer) in the directory where you’ll run the server, based on the env.sample file:

# .env
NEXTCLOUD_HOST=https://your.nextcloud.instance.com
NEXTCLOUD_USERNAME=your_nextcloud_username
NEXTCLOUD_PASSWORD=your_nextcloud_app_password_or_login_password

• NEXTCLOUD_HOST: The full URL of your Nextcloud instance.
• NEXTCLOUD_USERNAME: Your Nextcloud username.
• NEXTCLOUD_PASSWORD: Important: It is highly recommended to use a dedicated Nextcloud App Password for security. You can generate one in your Nextcloud Security settings. Alternatively, you can use your regular login password, but this is less secure.

Running the Server

Locally

Ensure your environment variables are loaded, then run the server using mcp run:

# Load environment variables from your .env file
export $(grep -v '^#' .env | xargs)

# Run the server
mcp run --transport sse nextcloud_mcp_server.server:mcp

The server will start, typically listening on http://0.0.0.0:8000.

Using Docker

Mount your environment file when running the container:

docker run -p 127.0.0.1:8000:8000 --env-file .env --rm ghcr.io/cbcoutinho/nextcloud-mcp-server:latest

This will start the server and expose it on port 8000 of your local machine.

Usage

Once the server is running, you can connect to it using an MCP client like uvx. Add the server to your uvx configuration:

uvx mcp add nextcloud-mcp http://localhost:8000 --default-transport sse

You can then interact with the server’s tools and resources through your LLM interface connected to uvx.
