Claude Code plugins and marketplace: 40 profiled in 2026
We profiled 40 Claude Code plugins, all from Anthropic. The largest group is 12 language server plugins that add code intelligence and diagnostics, such as typescript-lsp, pyright-lsp, gopls-lsp and rust-analyzer-lsp. The rest are workflow tools: code-review, pr-review-toolkit, feature-dev, commit-commands, hookify, ralph-loop and security-guidance.
There are also builder kits (plugin-dev, mcp-server-dev, agent-sdk-dev), two output-style plugins (explanatory-output-style, learning-output-style) and report tools (session-report, receipts). Most are Apache-2.0; claude-security is listed as proprietary. Anthropic warns to trust a plugin before installing, since it cannot verify the MCP servers, files or software a plugin includes.
- Oficial 40
Como funciona
- A plugin bundles slash commands, agents, skills, hooks or MCP server config into one installable unit.
- The official marketplace, claude-plugins-official, ships enabled by default in Claude Code; browse it with /plugin > Discover.
- Install with /plugin install <name>@claude-plugins-official, for example code-review@claude-plugins-official.
- Language server plugins need the matching language server on your machine; clangd-lsp, for example, is for .c files.
- Plugins can run hooks, so read the README first; ralph-loop uses a Stop hook and explanatory-output-style uses a SessionStart hook.
How a plugin is installed and configured
Official plugins come from the Anthropic marketplace; third-party ones are added by marketplace URL first. Each entry below shows the exact command from its README.
Arquivo: Terminal: /plugin · manifest .claude-plugin/plugin.json
# add a marketplace once, then install by name
/plugin marketplace add <owner>/<repo>
/plugin install <plugin-name>@<marketplace-name>
# example from the official marketplace
/plugin install commit-commands@claude-plugins-official
# minimal manifest in the plugin repo
.claude-plugin/plugin.json
