Security reflects where data goes, requested permissions and incidents on record at the verification date. It is not a guarantee of zero risk: check the deployment mode and the connections you enable.

What it does, concretely

Extending Claude Code with third-party plugins raises a trust issue: how can you tell whether a plugin is reliable, maintained, and free of malicious code? Anthropic's official directory centralises verified plugins to address this need.

The directory distinguishes two categories: internal plugins developed and maintained by Anthropic, and external plugins submitted by partners or the community, which must meet quality and security standards before approval. Installation is done directly from Claude Code using the command /plugin install {name}@claude-plugins-official or through the discovery interface /plugin > Discover.

Each plugin can include slash commands, agent definitions, skills, and an MCP server configuration. Skills are registered as <plugin-name>:<skill-name> in Claude Code, making them easy to identify and invoke precisely.

This directory is aimed at developers who use Claude Code daily and want to extend it with new capabilities without searching for plugins from unknown sources. It is not suited to those looking for highly specialised plugins not yet in the catalogue, or to those who want to publish a plugin without going through the official submission process.

What it offers

·Centralised catalogue of verified plugins, separating Anthropic internal plugins from approved external ones.
·One-command installation from Claude Code: /plugin install {name}@claude-plugins-official.
·Browse and discover available plugins directly via /plugin > Discover inside Claude Code.
·Support for skill-bundle plugins: a plugin can expose multiple skills from a repository without a dedicated manifest.
·Plugin rename management with automatic migration of existing installs via a mapping file.
·Open submission process for partners and the community via an official form, with quality and security validation.
·Standardised structure for each plugin: metadata, optional MCP configuration, commands, agents, and skills.

Our tips

Before installing an external plugin, check its homepage (the homepage field) to review the source code and maintenance history, as Anthropic does not control the content of third-party plugins.
To change how a plugin appears in the UI without breaking existing installs, use the displayName field rather than changing the name field, which is immutable once published.
If you are building a plugin from a repository that already contains SKILL.md files, use strict: false mode with an explicit skills array to expose them without creating an additional manifest.
If a plugin rename is unavoidable, add an entry to the renames map in .claude-plugin/marketplace.json so existing users are automatically migrated on their next sync.
Use the example plugin provided in /plugins/example-plugin as a reference implementation before submitting a new plugin to the directory.

Watch out

Anthropic does not control the content of external plugins (MCP servers, files, included software) and cannot guarantee they will work as intended or remain unchanged over time.
A plugin's technical name (name) is immutable after publication: a naming mistake at submission cannot be corrected without risking broken installs for existing users.
