claude-plugin-marketplace

500+ developer tools in one MCP server. Install once, get everything.

/plugin marketplace add barnburner121/claude-plugin-marketplace

Plugin Hub is the most comprehensive collection of developer tools available for Claude Code and Claude Cowork. Every tool runs through a single MCP server — no separate installations, no configuration sprawl, no dependency conflicts.

Install the marketplace:

/plugin marketplace add barnburner121/claude-plugin-marketplace

Install any plugin:

/plugin install <plugin-name>@barnburner121-plugins

Or use the MCP server directly:

{
  "mcpServers": {
    "plugin-hub": {
      "command": "npx",
      "args": ["-y", "@barnburner121/plugin-hub-mcp"]
    }
  }
}
