Adding Your Marketplace to Claude

This guide walks you through adding your Webrix plugin marketplace to Claude via the organization settings on claude.ai or the Anthropic Console.

Prerequisites​

Repository structure​

Webrix generates the following layout for Claude:

your-org-slug/
├── .claude-plugin/
│   └── marketplace.json
├── plugins/
│   └── <plugin-slug>/
│       ├── .claude-plugin/
│       │   └── plugin.json
│       ├── .mcp.json
│       └── skills/
│           └── <skill-slug>/
│               └── SKILL.md

Step 1: Open Organization Settings​

  1. Go to claude.ai and sign in with your admin account.
  2. Navigate to Organization settings in the left sidebar.
  3. Under Libraries, click Plugins.

Step 2: Add plugins​

Click the Add plugins button in the top right corner. You'll see two options:

Option A: Sync from GitHub​

Use this option if your marketplace is hosted on GitHub (recommended with Webrix).

  1. Select Sync from GitHub.
  2. Paste your GitHub repository URL (e.g. https://github.com/your-org/my-marketplace).
  3. Click Continue.
  4. Claude will parse your .claude-plugin/marketplace.json and display the list of plugins.
  5. Review the plugins and configure access settings.
  6. Click Save.

Your marketplace will appear in the Plugins list with a GitHub and Synced badge. You can click Update at any time to pull the latest version from your repository.

Option B: Upload a file​

Use this option to import your marketplace as a .zip file.

  1. Select Upload a file.
  2. Download the plugin zip from Webrix (from the plugin edit page, click Download Claude).
  3. Upload the .zip file.
  4. Claude will extract and parse the marketplace contents.
  5. Review the plugins and configure access settings.
  6. Click Save.

Step 3: Manage your marketplace​

Once added, your marketplace appears in the Plugins list. From here you can:

  • Update — Pull the latest version from GitHub (for synced marketplaces).
  • View plugins — Expand the marketplace to see all included plugins.
  • Configure access — Control which team members can see and install the plugins.
  • Remove — Delete the marketplace and its plugins.
