Title: No way to remove a registered marketplace from Claude Desktop

  Description:

  A marketplace ("Cloode-Marketplace") was added to my account, likely during a Cowork session. There is no UI in Claude Desktop
  (or on claude.ai) to unregister/remove it. The marketplace persists indefinitely.

  Details:

  - Marketplace name: Cloode-Marketplace
  - Marketplace ID: marketplace_01T7AYP3uyv6jXcZgvmYvPFt
  - Associated plugin: cabinet-of-imd (plugin ID: plugin_01YCc2fV74fbC5HTNbLUe78v)

  Investigation:

  The marketplace does not appear in any user-editable local config:
  - Not in cowork_settings.json
  - Not in cowork_plugins/known_marketplaces.json
  - Not in cowork_plugins/installed_plugins.json
  - Not in ~/.claude/settings.json

  It only appears in rpm/manifest.json (under ~/Library/Application
  Support/Claude/local-agent-mode-sessions/<session-id>/<org-id>/rpm/manifest.json), which is a server-synced file. Manually
  removing the entry from this file is overwritten on next launch — the server pushes the marketplace registration back and
  updates the lastUpdated timestamp.

  Expected behavior:

  Users should be able to remove marketplaces they've added, either through:
  - Claude Desktop UI (Settings > Plugins/Marketplaces)
  - A claude.ai account settings page
  - A local config file that isn't overwritten by server sync

  Environment:
  - macOS (Darwin 25.2.0)
  - Claude Desktop (Cowork/Code mode)

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

What's Wrong?

I have experimented with making my own skills and plug-ins for Claude. I've created a Git repo which I filled with my experiments, so I can add them both to Claude Desktop as well as the Code CLI app.

Right now -- this particular marketplace I added (old repo, since deprecated) keeps appearing in ANY instance of Claude Desktop, across devices etc. Clicking the three-dot menu to remove it prompts a successful deletion toast, but the marketplace itself factually never goes away.

This is a very frustrating issue, since it also limits my ability to add new marketplaces. Again would get successful addition toasts, with nothing in the UI implying it actually got fixed.

extent analysis

TL;DR

Manually removing the marketplace entry from the rpm/manifest.json file is not a viable solution as it gets overwritten by the server on next launch, so an alternative approach is needed to remove the registered marketplace from Claude Desktop.

Guidance

  • Investigate the server-side configuration to understand why the marketplace registration is being pushed back to the client, potentially involving the Anthropic API or Claude Code server settings.
  • Check the Claude Desktop UI (Settings > Plugins/Marketplaces) and claude.ai account settings page for any hidden or advanced options to remove marketplaces, as the expected behavior suggests these should be available.
  • Consider reaching out to the Claude Code support team or developers to report this issue and request assistance, as it appears to be a regression and the analysis suggests a server-side component is involved.
  • Review the cowork_settings.json, known_marketplaces.json, and installed_plugins.json files again to ensure the marketplace is not inadvertently referenced or configured elsewhere.

Notes

The provided analysis suggests that the issue is not solely client-side, as the rpm/manifest.json file is being updated by the server. Without more information about the server-side configuration or the Anthropic API, it's challenging to provide a definitive solution.

Recommendation

Apply workaround: Reach out to the Claude Code support team or developers to report this issue and request assistance, as it appears to be a regression and the analysis suggests a server-side component is involved.
