How to Set Up and Use Claude Plugins
Claude Plugins is a marketplace of 28 plugins and MCP servers purpose-built for Claude Code, providing ready-to-install skills for test-driven development, multi-agent orchestration, binary reverse engineering, cost-optimized code exploration, structured decision-making, Firebase workflows, and more. Each plugin installs in a single command and extends Claude Code's native capabilities without requiring any API keys or external services for most skills. It is maintained by 2389-research and designed to give Claude Code users immediate access to battle-tested agentic patterns rather than building them from scratch.
Prerequisites
- Claude Code installed and running
- Node.js and npm installed (for npx skill installer)
- Git access to pull plugin definitions from GitHub
- No external API keys required for most plugins; some MCP servers (slack-mcp) require workspace credentials
Add the claude-plugins marketplace to Claude Code
Install the marketplace plugin itself into Claude Code. This registers the plugin catalog so you can browse and install individual skills.
/plugin marketplace add 2389-research/claude-pluginsBrowse available plugins
View the 28 available plugins organized into categories: meta plugins, development tools, testing/quality, business/strategy, utilities, and MCP servers.
Install a plugin via npx (universal method)
Install any plugin directly using npx. Replace 'simmer' with the name of the plugin you want. This works outside of Claude Code as well.
npx skills add 2389-research/simmerInstall a plugin via Claude Code native command
Inside Claude Code, use the /plugin install command to add a specific plugin by name.
/plugin install simmer@2389-researchInstall MCP server plugins through Claude Code
Four plugins (journal, socialmedia, slack-mcp, agent-drugs) are MCP servers and must be installed via Claude Code's plugin system, not npx.
/plugin install agent-drugs@2389-researchClaude Plugins Examples
Client configuration
Configure Claude Desktop to access the claude-plugins MCP server for plugin management.

Once plugins are installed, use them in Claude Code to access specialized agentic workflows.
- "Use simmer to iteratively refine this function until all edge cases pass"
- "Run test-kitchen to generate a comprehensive test suite for this module"
- "Apply the binary-re skill to analyze this compiled binary for vulnerabilities"
- "Use deliberation to structure a decision about our database migration strategy"
- "Activate thrifty mode to complete this task using the most cost-efficient model delegation"Troubleshooting Claude Plugins
The /plugin command is not recognized in Claude Code
Ensure you are running an up-to-date version of Claude Code that supports the plugin system. Run 'claude --version' and update if needed. The marketplace plugin must be added first before individual plugins can be installed.
npx skills add fails with a not found error
Verify that Node.js 18+ and npm are installed. The 'skills' package is a separate npm tool — try 'npx --yes skills add 2389-research/simmer' to force download. Check your internet connection and npm registry access.
MCP server plugins (journal, slack-mcp) do not appear after installation
MCP server plugins require installation through Claude Code's native plugin system (/plugin install), not via npx. After installing, restart Claude Code to load the new MCP server into the active configuration.
