Introducing Agent Extensions

Since we launched the Agent Client Protocol, we've seen a bunch of ACP agents (most recently Auggie from Augment Code) as well as ACP clients (most recently the JetBrains family of IDEs). The ecosystem is growing faster than we expected!

Today we're making it easy for you to explore that growing ecosystem of agents. Zed's new Agent Server Extensions let you install an agent with one click and try it out right away.

Available Today: Augment, OpenCode, and Stakpak

We already have three Agent Server Extensions you can try out right now:

• Auggie from augmentcode.com
• OpenCode from opencode.ai
• Stakpak from stakpak.dev

You can install any of these by opening the Extensions panel and searching for them. As more Extensions get released, you can see them all at once by filtering extensions by Agent Servers in the Extensions panel—or by viewing all the Agent Server Extensions on our website.

What Agent Extensions Do

When you install one of these extensions, what you get is:

1. A menu item in Zed for starting a new thread with that agent
2. An automatic download of the agent's implementation, if necessary

Agents typically require some form of authentication, so as soon as you start a new thread, you can expect to go through whatever process that agent has for logging in.

Once you've done that, you're up and running with the new agent!

Add Your Agent to Zed

If you're developing an ACP-compatible agent, we'd like to help you reach Zed users! These new Agent Server Extensions make distribution straightforward: once the extension is published, anyone using Zed can install the agent with one click.

If you'd like to create one of these extensions, the steps are quick:

• Create an extension.toml which specifies things like the extension name and where to find its assets
• Add a SVG icon
• Publish it using the normal process

That's it! Check out our full Agent Server Extensions documentation for all the details.
