[FEATURE] Nextcloud Deck connector for Cowork

Preflight Checklist

• [x] This is a single feature request (not multiple features)

Problem Statement

Cowork offers vetted connectors for task and project management tools like Asana and Linear, but there is no connector for Nextcloud Deck, the Kanban board app built into Nextcloud. Users who self-host Nextcloud currently have no trusted way to let Claude read or manage their boards, lists, and cards, and have to fall back on unvetted community MCP servers, which carries security risks.

Proposed Solution

Add a vetted Cowork connector for Nextcloud Deck (using the Deck REST API) so Claude can list boards, read and create cards and lists, move cards between stages, and summarize open items — similar to how the existing Asana and Linear connectors work today.

Alternative Solutions

The only current option is a community-built MCP server for Nextcloud/Deck, which is not vetted by Anthropic and carries security risks for professional or enterprise use.

Priority

Medium - Would be very helpful

Feature Category

MCP server integration

Use Case Example

As a Nextcloud user I manage my tasks in Nextcloud Deck. I'd like to ask Claude in Cowork things like 'move the card for the Q3 report to Done' or 'summarize what's still open on my Deck board', without having to build a custom integration myself.
