Agent Plugin Marketplace
An agent plugin marketplace is a place to discover packaged skills and MCP servers for AI agents. Agent Plugins Directory currently lists 3,912 distinct packages from 1,607 publishing repositories, each verified against the Agent Plugins 1.0.0 schema on 2026-10-08. A verified listing proves manifest conformance; it does not prove availability in every client marketplace.
Browse the complete directory, search every current listing, or compare the installation routes for compatible clients.

Is this an official Agent Plugins marketplace?
No. Agent Plugins Directory is an independent, read-only discovery and verification layer. The open Agent Plugins 1.0.0 specification defines a portable package, but explicitly leaves registries, marketplaces, installation, updates, and enablement to each client. This site does not claim that a GitHub package is published in ChatGPT, Codex, Cursor, Copilot, VS Code, or Kiro merely because its plugin.json validates.
| Term | What it means here |
|---|---|
| Directory | The complete verified census and its stable detail pages |
| Marketplace | The browse-and-compare experience for people looking for agent plugins |
| Client marketplace | A registry configured inside a specific client, with its own availability and review rules |
| Installer | The client-controlled action that downloads or enables a package |
How do you evaluate a marketplace listing?
Open the plugin detail page and check four things before installation: the publisher and source repository, the skills named by the package, every MCP server and transport, and the license. Then inspect the source files. A valid schema does not make third-party instructions or executable MCP processes trustworthy.
The plugin.json validator checks a manifest against the official schema. The census JSON provides the same current dataset for tools and answer engines, while llms.txt maps the site's machine-readable resources.
How do client marketplaces differ?
Marketplace visibility is client-specific. Codex, ChatGPT, Cursor, GitHub Copilot, VS Code, and Kiro can expose different sources and installation flows even when they understand compatible components from the same portable package. Use the install hub and its per-client guides instead of assuming one listing appears everywhere.
For current Codex behavior, OpenAI documents plugins in its official help article and publishes the structure of its own plugin repository on GitHub. Those OpenAI distribution conventions are related to, but not identical with, a root Agent Plugins 1.0.0 manifest.
Is “agent-plugin-marketplace” also a plugin name?
Yes. The directory contains a third-party package named agent-plugin-marketplace. That detail page describes one package; this page owns the general query for browsing an agent plugin marketplace.
FAQ
How many plugins are in this marketplace? The current verified directory contains 3,912 distinct plugins from 1,607 publishing repositories as of 2026-10-08.
Are the listings free? This directory is free to browse. A package or client may impose separate requirements; verify those with its publisher and client marketplace.
Does “verified” mean safe? No. It means the fetched manifest conformed to Agent Plugins 1.0.0 at the stated verification date. Review skills, MCP commands, permissions, source, and publisher trust before installation.
Can a plugin appear here but not in Codex or ChatGPT? Yes. This directory discovers conformant public manifests. Client marketplace publication and installation are separate decisions.
