Where to Find the Community Plugin Marketplace for Claude

The Claude Community Plugin Marketplace is located at .claude-plugin/marketplace.json in the anthropics/claude-plugins-community repository, which contains the complete JSON catalogue of all community-published plugins.

The community plugin marketplace for Claude serves as the central registry for third-party extensions that extend Claude's capabilities. This marketplace is defined by a JSON manifest stored directly in the open-source repository, making it accessible for programmatic discovery and integration. Understanding the file structure and location enables developers to browse available plugins and understand how the ecosystem is organized.

Central Marketplace Location

The authoritative source for the community plugin marketplace is the manifest file located at the root of the repository:

• Path: .claude-plugin/marketplace.json
• GitHub URL: https://github.com/anthropics/claude-plugins-community/blob/main/.claude-plugin/marketplace.json

This file contains the complete catalogue of community-published plugins. According to the source code analysis, the manifest includes entries such as "name": "0x" with corresponding source URLs and SHA references, confirming this file serves as the definitive list of community plugins.

Manifest Structure and Metadata

The marketplace JSON follows a structured schema that organizes plugin metadata for machine readability. The top-level object contains two critical keys:

• "plugins" array: Contains the complete list of available community plugins, each with metadata including name, description, source repository, SHA reference, and homepage URL.
• "renames" map: Provides a lookup table for legacy plugin identifiers that have been renamed, ensuring backward compatibility.

Each entry in the plugins array exposes standardized fields that allow Claude clients to discover, verify, and load extensions safely.

Individual Plugin Manifests

In addition to the central marketplace file, individual plugin directories maintain their own local manifests. These per-plugin configurations follow the same JSON structure and are located at .claude-plugin/marketplace.json within each plugin's subdirectory:

• testdino/.claude-plugin/marketplace.json — Marketplace manifest for the testdino plugin collection
• quickdesign/.claude-plugin/marketplace.json — Marketplace manifest for the quickdesign plugin collection

These individual manifests allow plugin authors to bundle metadata directly with their source code while still being referenced by the central catalogue.

How to Access the Marketplace Programmatically

The marketplace JSON is accessible via the GitHub raw content URL, enabling direct programmatic consumption without cloning the repository.

Python Example

Load the marketplace manifest and list all plugin names:

import json
import requests

url = "https://raw.githubusercontent.com/anthropics/claude-plugins-community/main/.claude-plugin/marketplace.json"
data = json.loads(requests.get(url).text)

plugin_names = [p["name"] for p in data["plugins"]]
print("Available plugins:", plugin_names)

Command Line Example

Retrieve the marketplace JSON via curl and extract key fields:

curl -s https://raw.githubusercontent.com/anthropics/claude-plugins-community/main/.claude-plugin/marketplace.json \
| jq '.plugins[] | {name, description, homepage}'

JavaScript Example

Fetch the marketplace and filter by category:

fetch('https://raw.githubusercontent.com/anthropics/claude-plugins-community/main/.claude-plugin/marketplace.json')
  .then(r => r.json())
  .then(data => {
    const testingPlugins = data.plugins.filter(p => p.category === 'testing');
    console.log('Testing plugins:', testingPlugins.map(p => p.name));
  });
