Is sleek live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is sleek free to use?

No — it asks for a key or a login before it will serve.

What tools does sleek have?

11 tools: get_project, create_project, design, list_references, delete_project, get_design_run, get_component, list_components, ….

Is sleek safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

• get_project auth-required never probed

  Fetch a project and its projectUrl. Use it to confirm the project exists and share the URL with your user. Use list_components to see its screens.

• create_project auth-required never probed

  Create an empty project, then call design and screenshot. Creation is free and instant. Only design runs spend credits. Share projectUrl so your user can watch and edit the designs.

• design auth-required never probed

  Run Sleek's design agent to create or edit screens from a plain-language brief. Send the whole request as ONE message, such as 'a food delivery app with onboarding, restaurants, dish detail, cart, tracking, and profile'. The agent plans the screens together, so separate calls produce mismatched screens. A run spends workspace credits when it completes or saves changes. By default this waits for the run to finish. If it returns 'queued' or 'running', poll get_design_run. Only one run can be active per project. On CONFLICT, poll get_design_run until the run settles, then retry. cancel_design_run stops it sooner. If a failed run has data.error.url, your user has to act there, such as topping up credits, before you retry. On completion, share projectUrl with your user and call screenshot.

• list_references auth-required 1h ago

  List curated app styles and their preview images. When your user asks for a look such as Airbnb, brutalist, or dark fintech, pass the closest reference's id as referenceId to design. Without a reference, the agent picks a style.

• get_design_run auth-required never probed

  Poll a run that design returned as 'queued' or 'running'. Wait a few seconds between polls. On 'completed', data.result.operations lists the saved screens and theme changes. Share projectUrl and call screenshot. On 'failed', read data.error.message and send your user to data.error.url if present. A failed run, including a cancelled one, keeps what it saved in that same list and is charged only when the list is not empty. Check it before resending the brief.

• get_component auth-required 1h ago

  Fetch a screen's generated HTML. Returns only the version the screen currently shows. Use allVersions for the full history, which can be large. The returned screenId is the value design takes. Use this for a build handoff, not to check whether a design run worked.

• cancel_design_run auth-required never probed

  Ask a design run to stop, for example when the brief was wrong. A queued run never starts. A running run stops at its next step and stays 'running' until it settles. A run cut short settles as 'failed' with error code 'cancelled', or 'execution_failed' if saving its changes failed. It keeps any screens and theme changes it saved, listed in data.result.operations, and is charged only when that list is not empty. A run that had already finished settles as 'completed'. The project stays locked until the run settles, so poll get_design_run before starting another run. A run that stopped responding settles as 'failed' with error code 'execution_timeout' 15 minutes after creation.
