How to use Cline with Fabapp AI

Figures from September 17, 2026

Connecting Cline to your account

Cline is a VS Code extension and keeps MCP servers in a file of its own, which the extension's MCP panel opens for you to edit. The block is the usual one:

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

As soon as you save, the panel shows the server and the tools it offered.

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 Cline

Cline separates planning from acting, and that separation fits work on Fabapp well. Use the planning mode for it to read: the platform documentation, the project definition, the screens that already exist. Only then switch to acting.

The reason is concrete. The two things that most often go wrong when an assistant touches a Fabapp project are inventing a field type and writing the wrong access rule. Both fail closed, with no loud error: the field is refused, and the rule locks everybody out of their own records. Reading before writing is what prevents both, and the planning mode is literally that.

It is also worth approving change by change the first few times, until you get a feel for what it does with the schema.

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

What is the advantage of plan mode here?
It forces the right order: read the documentation and the definition before writing. The two most common failures, an invented field type and a wrong access rule, come from writing without reading, and both fail silently.
Does Cline need my Fabapp token?
No. It calls the MCP server, and the server uses the credential `login` already put in the keychain. No secret goes through the extension's configuration.
Can I review before publishing?
Yes. `npx @fabappai/cli deploy --no-publish` uploads without publishing, and you review in the Studio.
