Nextcloud MCP Server

MCP Endpoint: https://mcp.techmavie.digital/nextcloud/mcp

Note: This project is a complete rewrite in TypeScript of the original Python-based cbcoutinho/nextcloud-mcp-server, now with self-hosted VPS deployment and Smithery deployment support. ### Key Differences from the Original Repository: Language: This project is written in TypeScript, while the original is in Python. Smithery Support: Added full support for Smithery deployment and local testing via Smithery playground. Project Structure: The project structure has been adapted for a Node.js/TypeScript environment with MCP SDK integration. Dependencies: This project uses npm for package management, whereas the original uses Python's dependency management tools. * Deployment: Now supports both local development and cloud deployment via Smithery.

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 across Notes, Calendar, Contacts, Tables, and WebDAV file operations.

The hosted HTTP integration now supports a safer multi-user flow through the MCP Key Service. Instead of embedding raw Nextcloud credentials in the connector URL, hosted clients can use a user-scoped usr_... key and let the server resolve credentials server-side.

Features

The server provides integration with multiple Nextcloud apps, enabling LLMs to interact with your Nextcloud data through a comprehensive set of 30 tools across 5 main categories.

🔍 Revolutionary Unified WebDAV Search Feature

The crown jewel of this MCP server is the powerful unified search system for WebDAV files, inspired by modern search interfaces like on an another MCP that I have created: mcp-datagovmy. This completely transforms how you interact with your Nextcloud files by eliminating the need to specify exact file paths.

✨ Key Features

• 🎯 Multi-scope Search: Search across filenames, file content, and metadata simultaneously
• 🧠 Smart File Type Detection: Automatically handles text files, code, configuration files, documents, and media
• 🔧 Advanced Filtering: Filter by file type, size range, modification date, and directory
• 📈 Intelligent Ranking: Results ranked by relevance with bonuses for recent files and exact matches
• 👀 Content Preview: Optional content previews for matched text files
• ⚡ Performance Optimized: Intelligent caching, timeout protection, and parallel processing
• 🛡️ Error Recovery: Fallback strategies prevent timeouts and provide helpful suggestions

🚀 Usage Examples

// Basic search - find all files containing "FAQ Dean List"
await nextcloud_webdav_search_files({
  query: "FAQ Dean List"
});

// Advanced search - find PDF reports from 2024
await nextcloud_webdav_search_files({
  query: "report 2024",
  fileTypes: ["pdf"],
  searchIn: ["filename", "content"],
  limit: 20,
  includeContent: true,
  quickSearch: true
});

// Directory-specific search with date range
await nextcloud_webdav_search_files({
  query: "meeting notes",
  basePath: "/Documents",
  searchIn: ["filename", "content"],
  dateRange: {
    from: "2024-01-01",
    to: "2024-12-31"
  }
});

// Search by file characteristics
await nextcloud_webdav_search_files({
  query: "configuration files",
  sizeRange: { min: 1024, max: 102400 }, // 1KB - 100KB
  fileTypes: ["json", "yaml", "xml", "conf"]
});

// Quick search for large directories (optimized)
await nextcloud_webdav_search_files({
  query: "budget",
  basePath: "/", // Root directory
  quickSearch: true, // Enables optimizations
  limit: 25,
  maxDepth: 2 // Limit search depth
});

📋 Complete Parameter Reference

| Parameter | Type | Default | Description | Example | |-----------|------|---------|-------------|---------| | query | string | required | Search terms - supports multiple words | "FAQ Dean List" | | searchIn | array | ["filename", "content"] | Search scope: filename, content, metadata | ["filename", "content", "metadata"] | | fileTypes | array | all types | File extensions to include | ["pdf", "txt", "md", "docx"] | | basePath | string | "/" | Directory to search in | "/Documents/Reports" | | limit | number | 50 | Maximum results to return | 20 | | includeContent | boolean | false | Include content previews for text files | true | | caseSensitive | boolean | false | Case-sensitive matching | true | | quickSearch | boolean | true | Use optimized mode for root searches | false | | maxDepth | number | 3 | Maximum directory depth (1-10) | 5 | | sizeRange | object | unlimited | File size filters in bytes | {min: 1024, max: 1048576} | | dateRange | object | all dates | Last modified date filters | {from: "2024-01-01", to: "2024-12-31"} |

🎯 Performance Tips

• For root directory searches: Use quickSearch: true and maxDepth: 2-3 for faster results
• For specific directories: Use basePath: "/Documents" instead of searching root "/"
• For large result sets: Add fileTypes filter to narrow scope
• For timeout issues: Enable quickSearch and use smaller limit values

🔄 Before vs After: The Search Revolution

Before Unified Search

// You had to know exact paths
await nextcloud_webdav_read_file({
  path: "/Documents/Finance/Reports/Q4_Budget_Analysis_2024.pdf"
});

// Multiple calls needed to explore
await nextcloud_webdav_list_directory({ path: "/" });
await nextcloud_webdav_list_directory({ path: "/Documents" });
await nextcloud_webdav_list_directory({ path: "/Documents/Finance" });
// ... and so on

After Unified Search ✨

// Natural language search across entire Nextcloud!
await nextcloud_webdav_search_files({
  query: "Q4 budget analysis 2024",
  fileTypes: ["pdf"]
});

// Finds files instantly regardless of location!

🛠️ Advanced Search Strategies

Content-Aware Search

The system intelligently extracts and searches content from:

• 📝 Text Files: .txt, .md, .csv - Full content indexing
• 💻 Code Files: .js, .ts, .py, .html, .css - Syntax-aware search
• ⚙️ Config Files: .json, .xml, .yaml - Structure-aware indexing
• 📄 Documents: .pdf, .docx - Metadata and properties
• 🎬 Media Files: Images, videos - EXIF data and metadata

Smart Ranking System

Results are ranked using advanced algorithms:

1. Exact filename matches → 100 points
2. Word boundaries in filenames → 80 points
3. Partial filename matches → 60+ points (position bonus)
4. Content frequency matches → 50+ points (term density)
5. Recent file bonus → +10 points (last 30 days)
6. File type preference → +5 points (text/code files)
7. Size convenience → +5 points (files under 100KB)

Error Handling & Recovery

• 🕐 20-second timeout protection - Prevents hanging operations
• 🔄 Automatic fallback search - Falls back to directory listing if indexing fails
• 💡 Intelligent suggestions - Provides helpful tips for optimization
• 📊 Performance metrics - Shows search duration and result counts

Installation

Quick Start with npm (Recommended)

Install directly from npm and run as an MCP server:

# Install globally
npm install -g mcp-nextcloud

# Or install locally in your project
npm install mcp-nextcloud

Usage as MCP Server

After installation, you can run the MCP server directly:

# If installed globally
mcp-nextcloud

# If installed locally
npx mcp-nextcloud

# Or using npm script
npm exec mcp-nextcloud

Environment Setup: Create a .env file with your Nextcloud credentials:

NEXTCLOUD_HOST=https://your.nextcloud.instance.com
NEXTCLOUD_USERNAME=your_nextcloud_username
NEXTCLOUD_PASSWORD=your_nextcloud_app_password

Integration with LLM Applications

Add to your MCP client configuration (e.g., Claude Desktop, Continue, etc.):

For CLI mode (local, single-user): ``json { "mcpServers": { "nextcloud": { "command": "mcp-nextcloud", "env": { "NEXTCLOUD_HOST": "https://your.nextcloud.instance.com", "NEXTCLOUD_USERNAME": "your_username", "NEXTCLOUD_PASSWORD": "your_app_password" } } } } ``

For hosted HTTP mode (via MCP Key Service): ``json { "mcpServers": { "nextcloud": { "transport": "streamable-http", "url": "https://mcp.techmavie.digital/nextcloud/mcp/usr_XXXXXXXX" } } } ``

Recommended for hosted clients: Use the path-based URL form (/mcp/usr_...) for Claude.ai and similar hosted connectors. Keep the query-param form as a compatibility option for inspectors and clients that preserve query params reliably.

For self-hosted HTTP mode (your own server): ``json { "mcpServers": { "nextcloud": { "transport": "streamable-http", "url": "https://mcp.techmavie.digital/nextcloud/mcp", "headers": { "X-API-Key": "your-server-api-key", "X-Nextcloud-Host": "https://your.nextcloud.instance.com", "X-Nextcloud-Username": "your_username", "X-Nextcloud-Password": "your_app_password" } } } } ``

Prerequisites

• Node.js 18+
• Access to a Nextcloud instance
• npm or yarn package manager

Local Development Setup

1. Clone the repository:

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

1. Install dependencies:

    npm install

1. Configure your Nextcloud credentials (see Configuration section)

1. Build the project:

    npm run build

Configuration

Environment Variables

Create a .env file in the root directory based on .env.sample:

# --- CLI/stdio mode only ---
# These are used when running the server in CLI mode (npm run dev, npm run cli).
# They are NOT used by the HTTP server.
NEXTCLOUD_HOST=https://your.nextcloud.instance.com
NEXTCLOUD_USERNAME=your_nextcloud_username
NEXTCLOUD_PASSWORD=your_nextcloud_app_password

# --- HTTP server: Self-Hosted mode ---
# Required for self-hosted /mcp auth, and also used for /analytics access.
MCP_API_KEY=your-secret-api-key-here

# --- HTTP server: Key Service mode ---
# Set both to enable user api_key=usr_... resolution via the MCP Key Service.
# Users obtain and manage those keys at https://mcpkeys.techmavie.digital
# The MCP server itself talks to the resolver endpoint below.
KEY_SERVICE_URL=https://mcpkeys.techmavie.digital/internal/resolve
KEY_SERVICE_TOKEN=your-key-service-bearer-token

# Optional: Comma-separated list of allowed CORS origins.
ALLOWED_ORIGINS=https://smithery.ai,https://claude.ai

# Optional diagnostics for remote MCP debugging.
# These are intended for temporary troubleshooting in hosted HTTP mode.
MCP_TRACE_HTTP=false
ENABLE_MCP_DIAGNOSTICS=false

# Optional dedicated endpoint for Smithery URL publishing.
ENABLE_SMITHERY_ENDPOINT=false

Important Security Notes:

• Use a dedicated Nextcloud App Password instead of your regular login password. Generate one in your Nextcloud Security settings.
• In HTTP mode, NEXTCLOUD_ environment variables are never used. Self-hosted clients provide credentials via X-Nextcloud- headers, while key-service clients send only a usr_... key.
• Generate a strong API key: openssl rand -hex 32

Smithery Configuration

When deploying via Smithery, you can configure credentials through:

• Smithery's configuration interface for URL-published servers

For Smithery, the recommended model is:

• users enter nextcloudHost, nextcloudUsername, and nextcloudPassword directly
• Smithery forwards those values to the dedicated /smithery/mcp endpoint as headers
• the hosted usr_... key-service flow remains separate and continues to use /mcp/usr_...

Deployment & Usage

Option 1: Hosted Server (Recommended)

The easiest way to use this MCP server is via the hosted endpoint. No installation required!

Endpoint: https://mcp.techmavie.digital/nextcloud/mcp

Authentication

The hosted server uses the MCP Key Service for authentication. You get a personal API key (usr_XXXXXXXX) from the MCP Key Service portal:

https://mcpkeys.techmavie.digital

The server then resolves your Nextcloud credentials automatically through the resolver endpoint behind the scenes.

Why this is safer than the old query-credential approach:

• raw Nextcloud credentials are not embedded in the connector URL
• revoking a usr_... key is easier than rotating a user's underlying Nextcloud password everywhere
• server-side auditing and policy are easier to centralize
• support/debug workflows are safer because users share a scoped key, not their real Nextcloud password

Claude.ai / hosted connector URL (recommended):

https://mcp.techmavie.digital/nextcloud/mcp/usr_XXXXXXXX

Alternative URL for clients that preserve query params correctly:

https://mcp.techmavie.digital/nextcloud/mcp?api_key=usr_XXXXXXXX

Client Configuration

{
  "mcpServers": {
    "nextcloud": {
      "transport": "streamable-http",
      "url": "https://mcp.techmavie.digital/nextcloud/mcp/usr_XXXXXXXX"
    }
  }
}

Test with MCP Inspector

npx @modelcontextprotocol/inspector
# Select "Streamable HTTP"
# Enter URL: https://mcp.techmavie.digital/nextcloud/mcp/usr_XXXXXXXX

Option 2: Self-Hosted (VPS)

If you prefer to run your own instance, the built-in Docker + Nginx setup is:

# Set required environment variables
export MCP_API_KEY=your-secret-api-key  # Required for self-hosted /mcp auth and /analytics
export KEY_SERVICE_URL=https://mcpkeys.techmavie.digital/internal/resolve  # Optional: enables key service mode
export KEY_SERVICE_TOKEN=your-key-service-bearer-token                      # Optional: enables key service mode

# Using Docker
docker compose up -d --build

# Or run directly
npm run build
npm run start:http

Recommended VPS setup

1. Clone the repo onto your server:

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

1. Create a .env file with your server settings:

   MCP_API_KEY=your-secret-api-key
   KEY_SERVICE_URL=https://mcpkeys.techmavie.digital/internal/resolve
   KEY_SERVICE_TOKEN=your-key-service-bearer-token
   ALLOWED_ORIGINS=https://smithery.ai,https://claude.ai
   ENABLE_SMITHERY_ENDPOINT=false

Notes:

• Use KEY_SERVICE_URL + KEY_SERVICE_TOKEN only if you want hosted-style usr_... key resolution.
• Users obtain and manage those keys at https://mcpkeys.techmavie.digital.
• The MCP server itself should keep using the resolver endpoint path, not the portal homepage.
• Set ENABLE_SMITHERY_ENDPOINT=true only if you want to publish the dedicated Smithery direct-credentials endpoint.

1. Start the container:

   docker compose up -d --build

1. Add the reverse proxy config from deploy/nginx-mcp.conf to your nginx server block.
2. Validate and reload nginx:

   sudo nginx -t
   sudo systemctl reload nginx

1. Verify the server:

   curl http://127.0.0.1:8080/health

Important: The HTTP server does NOT use NEXTCLOUD_* environment variables. In self-hosted mode, each client must provide Nextcloud credentials via request headers. In key-service mode, clients send only api_key=usr_....

Remote MCP note: For hosted connectors such as Claude.ai, prefer the path-based URL form (/mcp/usr_...). Keep the query-param form as a compatibility option for inspectors and clients that preserve query params reliably.

Debugging note: If a hosted client shows a generic auth prompt, it does not automatically mean OAuth is required. First verify the auth-free diagnostics route, the key-service resolver response, and the actual initialize SSE body.

Option 3: npm Package (CLI)

Install and run as a local MCP server:

npm install -g mcp-nextcloud
mcp-nextcloud

Note: In CLI mode, credentials are read from environment variables (NEXTCLOUD_HOST, NEXTCLOUD_USERNAME, NEXTCLOUD_PASSWORD). This is safe because CLI mode runs locally for a single user.

Option 4: Smithery Deployment

For Smithery's current URL-published model, use a dedicated endpoint that accepts direct Nextcloud credentials via headers:

# Enable the Smithery endpoint on your hosted server
ENABLE_SMITHERY_ENDPOINT=true

Use this public MCP URL in Smithery:

https://mcp.techmavie.digital/nextcloud/smithery/mcp

Recommended Smithery config schema for this server:

{
  "type": "object",
  "properties": {
    "nextcloudHost": {
      "type": "string",
      "title": "Nextcloud Host",
      "description": "Nextcloud server URL (for example https://cloud.example.com)",
      "x-from": { "header": "X-Nextcloud-Host" }
    },
    "nextcloudUsername": {
      "type": "string",
      "title": "Nextcloud Username",
      "x-from": { "header": "X-Nextcloud-Username" }
    },
    "nextcloudPassword": {
      "type": "string",
      "title": "Nextcloud App Password",
      "format": "password",
      "x-from": { "header": "X-Nextcloud-Password" }
    }
  },
  "required": ["nextcloudHost", "nextcloudUsername", "nextcloudPassword"]
}

Why this split is recommended:

• Smithery users can connect directly without creating an MCP Key Service key first
• the hosted usr_... connector flow remains unchanged for Claude.ai and other hosted clients
• the Smithery path is isolated to /smithery/mcp, so it does not interfere with /mcp or /mcp/usr_...

Important: The Smithery endpoint is designed for direct credentials via headers. It does not use the MCP Key Service and does not require the shared MCP_API_KEY. To help Smithery discover tools without forcing a live authenticated scan, this server also exposes a static server card at https://mcp.techmavie.digital/.well-known/mcp/server-card.json. If your reverse proxy mounts the app under /nextcloud, make sure that exact root-level well-known path is proxied to the app.

Publishing Checklist

• [ ] All tests pass (Smithery deployment confirmed working)
• [ ] TypeScript builds without errors (npm run build)
• [ ] Version bumped appropriately (npm version)
• [ ] README updated with changes
• [ ] .npmignore properly excludes development files
• [ ] CLI executable works (dist/cli.js)

Dual Deployment Strategy

This project supports both deployment methods simultaneously:

• Smithery: For cloud deployment and development testing
• npm: For end-user installation and MCP client integration

The Smithery configuration (smithery.yaml) and npm package configuration coexist without interference.

Smithery Integration

This project includes full Smithery support with:

• smithery.yaml: Specifies TypeScript runtime
• Development server: Local testing with hot reload
• One-click deployment: Deploy to cloud with a single command
• Configuration management: Secure credential handling
• Playground integration: Immediate testing interface

Security

HTTP Server Security Model

The HTTP server (http-server.ts) supports two authentication modes:

Key Service Mode (hosted/multi-user):

• User API keys (usr_...) are resolved via the MCP Key Service which returns encrypted Nextcloud credentials.
• No raw credentials are sent by the client - only the user-scoped API key.
• Credentials are cached for 60 seconds to reduce key service load, then re-validated.

Self-Hosted Mode (single-operator):

• A server-side MCP_API_KEY validates access.
• Each client provides Nextcloud credentials via X-Nextcloud-* headers.

Common security measures:

• Per-Request Credential Isolation: Each request gets its own isolated set of Nextcloud clients via AsyncLocalStorage. No credential state is shared between requests.
• No Environment Variable Fallback: The HTTP server never falls back to NEXTCLOUD_* environment variables for credentials. These are only used in CLI mode.
• Restricted CORS: Only origins listed in ALLOWED_ORIGINS are permitted (defaults to smithery.ai and claude.ai).
• Protected Analytics: The /analytics endpoint requires MCP_API_KEY authentication in both modes. The dashboard page stores the key in session storage, never in the URL. Client IPs are hashed before storage.
• Debug Tools Disabled in Production: Calendar debug tools are automatically disabled when NODE_ENV=production.

Self-Hosting Checklist

If you deploy your own instance:

1. Choose an auth mode: set KEY_SERVICE_URL + KEY_SERVICE_TOKEN for key service, or MCP_API_KEY for self-hosted
2. Set MCP_API_KEY for analytics access (required in both modes)
3. Do NOT set NEXTCLOUD_* environment variables on the HTTP server
4. Use HTTPS (TLS) for all connections
5. Configure ALLOWED_ORIGINS to restrict which domains can connect
6. Use Nextcloud App Passwords (not your main login password)

Troubleshooting

Common Issues

1. 404 Errors on WebDAV/Calendar/Contacts:

• Ensure your Nextcloud credentials are correct
• Verify the Nextcloud apps (Calendar, Contacts) are installed and enabled
• Check that your app password has the necessary permissions

1. Authentication Failures:

• Use an App Password instead of your regular password
• Verify the NEXTCLOUD_HOST URL is correct (including https://)
• Ensure the Nextcloud instance is accessible

1. Missing Tools:

• Run the hello tool to verify all 30 tools are available
• Check the server logs for any initialization errors

1. Search Timeout Issues:

• Use quickSearch: true for root directory searches
• Specify a basePath like "/Documents" instead of searching root "/"
• Add fileTypes filters to narrow the search scope
• Reduce maxDepth parameter for faster results

Hosted HTTP / Claude.ai Debugging

If the hosted connector still fails, use this order:

1. Verify the auth-free diagnostics route first:

• enable ENABLE_MCP_DIAGNOSTICS=true
• test /mcp-debug/open
• if this works, the issue is likely auth or an upstream dependency, not basic MCP transport

1. Verify the key-service resolver directly from the deployed MCP host:

   curl -i -X POST "$KEY_SERVICE_URL" \
     -H "Authorization: Bearer $KEY_SERVICE_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"key":"usr_..."}'

Expected:

• 200 OK
• Content-Type: application/json
• valid JSON response

1. Verify the MCP initialize response body, not just the status code:

   curl -N --max-time 10 -X POST "https://mcp.techmavie.digital/nextcloud/mcp/usr_XXXXXXXX" \
     -H "Content-Type: application/json" \
     -H "Accept: application/json, text/event-stream" \
     -d '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":"2025-03-26","capabilities":{},"clientInfo":{"name":"probe","version":"1.0.0"}}}'

Expected:

• 200 OK
• Content-Type: text/event-stream
• non-empty SSE initialize response body

1. If the hosted client keeps retrying the same initialize request every few seconds, suspect an empty or malformed SSE initialize response even if the HTTP status is 200.
2. Enable temporary tracing with MCP_TRACE_HTTP=true and inspect:

• final status code
• request accept
• request content-type
• content-type response header
• auth outcome (resolved, invalid_key, service_unavailable, malformed_response)
