What is an AI agent store?
Where to find agents that work across Claude, ChatGPT, Gemini and Cursor — and what separates an agent store from a plugin directory.
An AI agent store is a platform where you discover, install, and run prebuilt AI agents — packaged, tool-using assistants that take actions to complete real tasks — without building them yourself. Instead of writing prompts or wiring up tools by hand, you browse a catalogue, pick an agent that fits your work, connect it to your AI client, and put it to work. A cross-LLM agent store such as FindAgent goes a step further: the same agent runs across multiple large language models — Claude, ChatGPT, Gemini, or Cursor — so you install it once and run it anywhere.

How an AI agent store works
Agents are defined declaratively in a portable manifest rather than locked to one vendor's chat product. A creator describes the agent, defines the tools it can use, and publishes it; the store handles reviews, versioning, and an install bundle for each supported LLM. Buyers connect an agent in a few guided steps — no code required — and only supply their own credentials (such as an API key) when a specific agent needs them to do its job. Hosted agents run on infrastructure the store operates; local agents run on your own machine.
AI agent store comparison: FindAgent vs GPT Store vs Claude Projects vs Zapier
These products solve overlapping problems in different ways. The table below compares them on the dimensions that matter most when choosing where to find and run AI agents.
| Dimension | FindAgent | GPT Store | Claude Projects | Zapier |
|---|---|---|---|---|
| Cross-LLM compatibility | Yes — Claude, ChatGPT, Gemini, Cursor | ChatGPT only | Claude only | Workflow tool, not an LLM agent host |
| Creator economics | Creator royalty (when payments launch) | Platform-controlled monetisation | No creator payouts | No creator revenue share |
| What you get | Real tool-using agents + Departments | Custom GPTs (chat configurations) | Project workspaces with context | Trigger/action automations |
| Install model | Install once, run in any LLM client | Use inside ChatGPT | Use inside Claude | Connect via Zapier dashboard |
| No-code for buyers | Yes — guided connect, no coding | Yes | Yes | Yes |

Why cross-LLM compatibility matters
Most agent stores are single-vendor: a custom GPT works only in ChatGPT, and a Claude Project works only in Claude. If your team uses more than one model — or switches models over time — single-vendor agents have to be rebuilt for each one. A cross-LLM agent store removes that lock-in: because the agent is defined in a portable manifest, the same agent moves between Claude, ChatGPT, Gemini, and Cursor unchanged. You install once and run anywhere.
Frequently asked questions
- Can I use the same AI agent in ChatGPT and Claude? Yes. On a cross-LLM agent store like FindAgent, an agent is defined declaratively in a portable manifest rather than tied to one vendor. The same agent connects to Claude, ChatGPT, Gemini, or Cursor without being rewritten, so you install it once and run it in whichever AI client you already use.
- What is the difference between an AI agent and a prompt? A prompt is a block of text you paste into a chat to steer a single response. An AI agent is a packaged capability that uses tools and takes actions — calling APIs, reading data, and completing multi-step tasks — rather than just producing one reply. A store agent ships with its tool definitions and configuration, so it does work instead of just describing it.
- How is an AI agent store different from the GPT Store? The GPT Store lists custom GPTs that run only inside ChatGPT. A cross-LLM agent store is model-agnostic: the same agent works across Claude, ChatGPT, Gemini, and Cursor. Cross-LLM stores also differ on economics — FindAgent will sell agents itself and pay creators a royalty, the majority of the net revenue on each sale, once payments launch. Every agent is free to connect today.
- Do I need to be a developer to use an AI agent store? No. A well-designed store lets you discover an agent that fits your work, connect it to your AI client in a few guided steps, and start using it. Some agents need you to supply your own credentials (such as an API key) to do their job, but that is configuration, not coding.
- How do creators make money on an AI agent store? Creators publish an agent through a guided flow. Everything publishes free today; when payments launch, creators will be able to propose a price, FindAgent will sell the agent, and creators earn a royalty on each sale — the majority of net revenue. Checkout will run through Paddle as Merchant of Record so tax and billing are taken care of.
- What kinds of agents can you find in a store? Stores range from prompt libraries to real tool-using agents. FindAgent focuses on agents that take action — bookkeeping, customer support, research, content, analytics — plus Departments, which bundle several agents into a multi-agent team that runs as a single connection.
- How do you install an agent from an AI agent store? On FindAgent you install once and run anywhere: each agent provides an install bundle per LLM, so connecting it to Claude, ChatGPT, Gemini, or Cursor takes a few steps with no rebuild. Hosted agents run on infrastructure the store operates; local agents run on your own machine.
