nextcloud-talk-mcp

An MCP server for Nextcloud Talk (Spreed) — 24 tools covering conversations, messages, participants, reactions, reminders, and file sharing, for use with Claude Desktop and any other MCP client.

It is the first MCP server to cover Talk; the established Nextcloud MCP servers cover Notes / Calendar / Contacts / Tables / WebDAV but not Spreed. A thin wrapper over nextcloud-talk-core, where all endpoint logic and the typed models live.

Install

uvx nextcloud-talk-mcp          # run without installing
pipx install nextcloud-talk-mcp # or install globally
pip install nextcloud-talk-mcp  # or into a venv

Configure

The server reads three environment variables:

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS):

{
  "mcpServers": {
    "nextcloud-talk": {
      "command": "uvx",
      "args": ["nextcloud-talk-mcp"],
      "env": {
        "NC_URL": "https://cloud.example.com",
        "NC_USER": "your-username",
        "NC_APP_PASSWORD": "xxxxx-xxxxx-xxxxx-xxxxx"
      }
    }
  }
}

Tools

Conversations (list_conversations, create_conversation, rename_conversation, set_description, delete_conversation), messages (read_messages, send_message, edit_message, delete_message, wait_for_messages, list_mentions), read-markers (mark_as_read, mark_as_unread), participants (list_participants, add_participant, remove_participant, set_participant_permissions), reactions (add_reaction, remove_reaction, list_reactions), reminders (set_reminder, get_reminder, delete_reminder), and file sharing (share_file_to_conversation). Read-only tools carry readOnlyHint; destructive ones carry destructiveHint so clients prompt first.
