Plugin Hub — The Largest Claude Code Plugin Marketplace
500+ developer tools in one MCP server. Install once, get everything.
/plugin marketplace add barnburner121/claude-plugin-marketplacePlugin 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.
Quick Start
Install the marketplace:
/plugin marketplace add barnburner121/claude-plugin-marketplaceInstall any plugin:
/plugin install <plugin-name>@barnburner121-pluginsOr use the MCP server directly:
{
"mcpServers": {
"plugin-hub": {
"command": "npx",
"args": ["-y", "@barnburner121/plugin-hub-mcp"]
}
}
