How to use Zed with Fabapp AI

Figures from September 17, 2026

Connecting Zed to your account

In Zed, MCP servers are context servers, declared in the editor's settings.json. The command is the usual one:

{ "context_servers": { "fabapp": { "command": { "path": "npx", "args": ["-y", "@fabappai/cli", "mcp"] } } } }

If your version of Zed arranges that block differently, its documentation is what counts. The part that is ours, and does not change, is npx -y @fabappai/cli mcp.

What you need

Node 20 or newer, a Fabapp account on the Builder plan or above, and a single login:

npx @fabappai/cli login

The credential goes into the system keychain. It is never displayed, and it is revoked from one place, in the panel.

The loop

npx @fabappai/cli create "My store"
npx @fabappai/cli dev

dev assembles the app on your machine on the same template the platform publishes with, installs the dependencies and starts the local server. With it running, ask for what you would do by hand: read the definition, create the entities, write the screens. Then:

npx @fabappai/cli deploy

It uploads what you changed and publishes, in that order. Publishing before uploading would publish what is on the server, and your work would be left behind.

What is different about Zed

Zed is fast, and people who pick it usually pick it for that. The gain here is that the short loop is genuinely short: dev runs in the integrated terminal, the app reloads on save, and the agent panel sits alongside without weighing anything down.

What is worth adjusting is the expectation of what is fast. Editing a screen and seeing it in the browser is instant. Publishing is not: deploy uploads the files and the platform builds the app for real, with dependency installation and a build. That is why dev exists. Publish when it is ready, not on every change.

What to ask for

"Read the platform documentation before writing the schema." The field types are a closed list and anything else is refused; the access rules are the only thing between an app's data and the public.

"Read the current definition before changing it." Without the schema at hand, a wrong model id answers 404 and an invented field answers 422.

"Schema first, screens after." The SDK is generated against the data model.

Frequently asked questions

Why does publishing take longer than saving?
Because publishing builds the app for real on the server, with dependency installation and a build. `dev` exists so you do not need that on every change.
Does Zed support MCP natively?
Yes, through context servers. The command is the same as in any other client; only the block's shape changes.
Can I see which tools it received?
You can, in the agent panel. A short list means that machine's credential is read-only.
