AI Agent Plugins Directory
What AI agent plugins are, why a directory helps you choose them, and where to find the ones worth installing — with a focus on the DeepSeek Harness (dsh) ecosystem.
An AI agent plugin is a piece of code that extends an agent runtime with a new capability: a tool the model can call, an integration with an external service, a UI panel, a memory system, even a whole sub-agent. Instead of rebuilding your agent for every task, you assemble it from plugins.
Directories matter because plugins are how agent ecosystems grow. A good catalog tells you what exists, what is maintained, and what is worth installing before you wire third-party code into a system that can run commands on your machine. This site is one such directory — with an honest scope: we catalog the DeepSeek Harness (dsh) plugin ecosystem, where the tools, model adapters and the UI are all plugins. We do not pretend to index every agent framework on the internet.
If you build on dsh, this is the full catalog. If you are comparing agent ecosystems, the category map below shows what a real agent plugin ecosystem contains — from agent loops and MCP servers to themes and desktop apps.

Frequently asked questions
Quick answers about AI agent plugins and this directory.
What is an AI agent plugin?
A plugin that extends an AI agent's runtime: a new tool the model can call, a bridge to an external service, a UI module, a memory store or a workflow. In DeepSeek Harness the idea goes furthest — the tools, model adapters, UI and even the main agent loop are all plugins, so the line between the agent and its plugins is thin.
Does this directory cover all AI agent plugins?
No — and we say so up front. This catalog focuses on the DeepSeek Harness (dsh) ecosystem: plugins built for dsh's plugin tree, profiles and tool pipeline. That focus is the point — every entry installs into the same runtime, under the same approval and sandbox model. Generic "AI agent" lists mix incompatible frameworks; this one doesn't.
Are these plugins free?
Almost all entries are open source on GitHub — check each repo's license, shown on every plugin page. Using a plugin still means running model calls through your own provider account, which bills you for tokens separately.
How do I install an AI agent plugin?
In dsh, installing a plugin usually means adding one entry to your profile or patch config — the plugin's README documents its exact line. The plugin then loads into the plugin tree, and removing the line removes everything it registered. Our step-by-step guide covers installation and how to vet third-party code safely.
