Nextcloud MCP Connector
Overview
This skill enables Claude to interact with Nextcloud through the Model Context Protocol (MCP). It provides a bridge between Claude's AI capabilities and Nextcloud's WebDAV/OCS API, allowing natural language control of Nextcloud operations, intelligent automation, and AI-powered assistance for Nextcloud workflows.
When to Use This Skill
- File and folder management via natural language
- Share and permission configuration
- Calendar and contact management
- App installation and configuration
- User and group administration

Core Concepts
MCP Server Setup
The connector implements an MCP server that exposes Nextcloud operations as tools Claude can invoke. The server translates natural language intentions into WebDAV/OCS API calls.
Key Endpoints/Interfaces
/remote.php/dav/files, /ocs/v2.php/apps/files_sharing/api/v1, /ocs/v2.php/cloud/users, /ocs/v2.php/apps/notifications
Implementation
import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js";
import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
import { z } from "zod";
const server = new McpServer({
name: "nextcloud-mcp-connector",
version: "1.0.0",
});
server.tool(
"list_resources",
"List and query Nextcloud resources with optional filters",
{
query: z.string().optional().describe("Search query or filter"),
limit: z.number().optional().describe("Max results to return"),
},
async ({ query, limit }) => {
const response = await fetch(`${BASE_URL}/remote.php/dav/files`, {
headers: { "Authorization": `Bearer ${API_KEY}` },
});
const data = await response.json();
return {
content: [{ type: "text", text: JSON.stringify(data, null, 2) }],
};
}
);
server.tool(
"create_resource",
"Create a new resource in Nextcloud",
{
name: z.string().describe("Resource name"),
config: z.object({}).passthrough().optional().describe("Resource configuration"),
},
async ({ name, config }) => {
const response = await fetch(`${BASE_URL}/remote.php/dav/files`, {
method: "POST",
headers: {
"Authorization": `Bearer ${API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({ name, ...config }),
});
const data = await response.json();
return {
content: [{ type: "text", text: `Created: ${JSON.stringify(data)}` }],
};
}
);
server.tool(
"analyze",
"AI-powered analysis of Nextcloud data",
{
type: z.string().describe("Analysis type"),
timeframe: z.string().optional().describe("Time range for analysis"),
},
async ({ type, timeframe }) => {
const response = await fetch(`${BASE_URL}/remote.php/dav/files`, {
headers: { "Authorization": `Bearer ${API_KEY}` },
});
const data = await response.json();
return {
content: [{ type: "text", text: JSON.stringify(data, null, 2) }],
};
}
);
const transport = new StdioServerTransport();
await server.connect(transport);
Claude Desktop Configuration

"mcpServers": {
"nextcloud-mcp-connector": {
"command": "node",
"args": ["path/to/nextcloud-mcp-connector/index.js"],

Best Practices
- Authentication: Store API keys securely using environment variables; never hardcode credentials
- Rate Limiting: Implement request throttling to respect Nextcloud API rate limits
- Error Handling: Provide clear, actionable error messages for common failure scenarios
- Pagination: Handle paginated responses for large datasets efficiently
- Caching: Cache frequently accessed read-only data to reduce API calls
- Security: Validate all inputs before passing to the Nextcloud API; sanitize outputs
- Logging: Log all API interactions for debugging and audit purposes
Example Prompts
"Share the project folder with the team group with edit permissions and set up a download link for clients"
Security Considerations
- All API credentials must be stored as environment variables
- Implement input validation and sanitization for all tool parameters
- Use HTTPS for all API communications
- Follow the principle of least privilege for API token permissions
- Audit log all write operations for compliance tracking
