Claude Marketplace Plugin Categories: Complete List and How to Use Them

The Claude Marketplace organizes community-contributed plugins into 13 distinct categories including testing, productivity, development, location, finance, monitoring, deployment, design, database, security, learning, automation, and Developer Tools.

Each plugin in the anthropics/claude-plugins-community repository declares its category in the "category" field of the marketplace manifest. Understanding these categories helps you quickly discover tools that match your workflow, whether you need AI-powered testing frameworks or database management utilities.

How Plugin Categories Are Defined

The authoritative source for all category assignments is .claude-plugin/marketplace.json. This JSON file serves as the master manifest for the Claude Marketplace, with each plugin entry containing metadata including its assigned category.

Categories are not hierarchical—each plugin maps to exactly one category value. The current snapshot reveals both lowercase snake_case labels (security, automation) and title-case variants (Developer Tools), reflecting organic growth of the taxonomy over time.

Working with Categories via CLI

The Claude CLI provides built-in filters to query plugins by their assigned categories. These commands read directly from the same marketplace.json structure.

List all plugins in a specific category:

claude plugin list --category development

Install a plugin from a particular category:

claude plugin install adup-ai-marketing-agent@claude-community

Search within a category for specific functionality:

claude plugin search --category security "auth0"

Generate distribution statistics:

claude plugin stats --group-by category

Key Files for Plugin Category Research

File	Purpose
.claude-plugin/marketplace.json	Master manifest containing all plugin metadata including the "category" field
README.md	Repository overview and installation instructions
opencode.json	Opencode tooling metadata (infrastructure, not category-related)

All category assignments originate in marketplace.json. When the marketplace updates, this file reflects new categories or reassignments immediately.

Frequently Asked Questions

How do I find which category a specific plugin belongs to?

Search the marketplace.json file for the plugin name, then inspect its "category" field. Each plugin entry is a JSON object with consistent top-level keys including name, description, and category.

Can plugins belong to multiple categories?

No. The current schema assigns exactly one category string per plugin. If you need cross-cutting functionality, use claude plugin search with keywords rather than filtering by category alone.

What is the most populated category in the Claude Marketplace?

The source JSON shows significant clustering around development, productivity, and security, though exact counts require parsing the full manifest. Run claude plugin stats --group-by category for real-time distributions.

How are new categories added to the marketplace?

New categories emerge organically when plugin authors propose entries with novel category values. The anthropics/claude-plugins-community maintainers may eventually normalize these into the official taxonomy, as seen with the Developer Tools title-case variant standardizing earlier inconsistent labels.
