Add the Nextcloud MCP server to Claude Code

Config last verified Jun 1, 2026

The exact config to run Nextcloud in Claude Code — paste it in, restart, and the tools load.

Prerequisites

Claude Code installed.
NEXTCLOUD_HOST — Base URL of your Nextcloud instance. Required.
NEXTCLOUD_USERNAME — Nextcloud username. Required.
NEXTCLOUD_PASSWORD — Nextcloud app password. Required.

Setup

1. Open `~/.claude.json`

2. Add this configuration

Add to ~/.claude.json

~/.claude.json

json

{
  "mcpServers": {
    "nextcloud": {
      "command": "uvx",
      "args": [
        "nextcloud-mcp-server",
        "run",
        "--transport",
        "stdio"
      ],
      "env": {
        "NEXTCLOUD_HOST": "<NEXTCLOUD_HOST>",
        "NEXTCLOUD_USERNAME": "<NEXTCLOUD_USERNAME>",
        "NEXTCLOUD_PASSWORD": "<NEXTCLOUD_PASSWORD>"
      }
    }
  }
}

Or via CLI

bash

claude mcp add nextcloud -- uvx nextcloud-mcp-server run --transport stdio

3. Restart Claude Code and confirm the Nextcloud tools load.

Gotchas

Claude Code stores MCP servers under an "mcpServers" object in ~/.claude.json. It also reads a project-scoped .mcp.json and supports adding servers from the command line with "claude mcp add". Each entry must declare either a "type" or a "command"; Claude Code refuses an entry that has neither. Remote servers connect natively over Streamable HTTP with OAuth.
