AgentKit is a developer toolkit for building AI agents, available through GitHub and npm

AgentKit is an open-source framework that helps developers create AI agents — software that can take actions on your behalf using artificial intelligence. You can find it on GitHub under the Coinbase organization, and install it through npm (Node Package Manager) if you work with JavaScript or TypeScript projects.

The toolkit is designed for developers who want to build agents that can interact with blockchain networks, APIs, and other systems. It is not a finished product you download and use directly — it is a set of code and tools that developers use as a starting point for their own projects.

Key Takeaways

  • AgentKit lives on GitHub at github.com/coinbase/agentkit and is free to access and use.
  • You install it through npm using the command line if you are building a JavaScript or TypeScript project.
  • The toolkit includes documentation, code examples, and templates to help you get your free guide building AI agents.
  • You need basic developer knowledge — familiarity with Node.js, npm, and command-line tools — to use it effectively.
  • AgentKit is maintained by Coinbase and updated regularly, so checking GitHub for the latest version is important before you start a new project.

Finding AgentKit on GitHub

Go to github.com and search for "coinbase agentkit" or navigate directly to github.com/coinbase/agentkit. The repository page shows the code, documentation, and all the files you need. On the right side of the page, you will see a green button labeled "Code" — click it to see your options for downloading or cloning the repository.

The repository includes a README file that explains what AgentKit does and how to get your free guide. This is the first place to read because it tells you what version of Node.js you need, what dependencies the project requires, and whether AgentKit is the right tool for what you are trying to build.

GitHub also shows you the release history, which lists all the versions that have been published. If you are starting a new project, use the most recent stable release rather than an older version, because newer versions include bug fixes and new features.

Installing AgentKit Through npm

If you already have a JavaScript or TypeScript project set up with Node.js and npm installed, you can add AgentKit to it using the command line. Open your terminal or command prompt, navigate to your project folder, and run the npm install command shown in the GitHub repository documentation.

The exact command will look something like npm install @coinbase/agentkit, though the exact package name may vary depending on the current version. Always copy the command directly from the GitHub README to make sure you are installing the right package.

After installation completes, npm creates a folder called node_modules in your project and adds AgentKit to your package.json file. This tells npm that your project depends on AgentKit, so anyone else who clones your project can install the same version by running npm install.

What You Will Find in the Repository

The GitHub repository contains the source code, but also includes examples, documentation, and configuration files. The examples folder shows you how to build a basic agent, how to connect it to different APIs, and how to handle common tasks like authentication and error handling.

The documentation folder (often called docs or README sections) explains the core concepts — what an agent is, how it makes decisions, what actions it can perform, and how to extend it with your own custom actions. This documentation is written for developers, so it assumes you understand JavaScript or TypeScript and basic programming concepts.

You will also find a LICENSE file, which tells you how you can use the code. AgentKit is typically released under an open-source license that allows you to use it for free, modify it, and distribute it under certain conditions. Read the license if you plan to use AgentKit in a commercial product.

Checking for Updates and Staying Current

GitHub shows you when the repository was last updated and how frequently the maintainers release new versions. Click the "Releases" tab on the repository page to see all published versions, what changed in each one, and download links for each release.

If you have already installed AgentKit in a project, you can check for updates by running npm outdated in your project folder. This shows you which packages have newer versions available. To update AgentKit to the latest version, run npm update @coinbase/agentkit (or whatever the package name is).

Before updating to a new version, read the release notes on GitHub to understand what changed. Sometimes new versions include breaking changes that require you to modify your code, so it is worth knowing what you are getting into before you update.

Alternatives if AgentKit Does Not Fit Your Needs

AgentKit is specifically designed for building agents that work with blockchain and Coinbase services. If you are building an AI agent for a different purpose — like chatbots, automation tools, or general-purpose AI applications — other frameworks may be a better fit.

LangChain, CrewAI, and AutoGen are other open-source agent frameworks available on GitHub. Each one has different strengths: LangChain focuses on language models and chains of reasoning, CrewAI emphasizes multi-agent collaboration, and AutoGen specializes in agents that can talk to each other. Search GitHub for these names to explore them, or check their official websites for comparison guides.

If you are not sure whether you need an agent framework at all, start by asking what you want the software to do. If it needs to make decisions, take multiple steps, or interact with external systems based on user input, an agent framework is probably useful. If you just need to call an API or process data, a simpler library might be enough.

Frequently Asked Questions

Do I need to know blockchain to use AgentKit?

Not necessarily. AgentKit handles blockchain interactions for you, so you can build agents without deep blockchain knowledge. However, understanding basic concepts like wallets, transactions, and smart contracts will help you design better agents. The documentation includes explanations of these concepts for developers new to blockchain.

Can I use AgentKit if I do not know JavaScript?

AgentKit is built for JavaScript and TypeScript, so you need at least basic familiarity with one of those languages. If you know Python or another language but not JavaScript, you would need to learn JavaScript first, or look for agent frameworks built in your preferred language.

Is AgentKit free to use?

Yes, AgentKit itself is free and open-source. However, using it may involve costs if you call paid APIs or blockchain services. For example, interacting with certain blockchain networks or Coinbase services may have transaction fees or API costs depending on what your agent does.

Where do I ask questions if I get stuck?

GitHub repositories usually have a Discussions tab or Issues section where developers ask questions and report problems. You can also check if Coinbase maintains a Discord server or community forum for AgentKit users. The README typically links to these community resources.

How often is AgentKit updated?

Update frequency varies. Check the Releases tab on GitHub to see how often new versions come out. Some projects release updates monthly, others quarterly. The commit history shows you how actively the code is being worked on day-to-day.
