Is coolours live?

Yes — it answered the hub's last check (checked 43m ago). It answered 100% of checks over the last 30 days.

Is coolours free to use?

Yes — the hub reached it with no key and no payment.

What tools does coolours have?

3 tools: create_palette_link, export_palette, parse_palette_link.

Is coolours 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.

• create_palette_link unknown never probed

  Turn a colour palette you have chosen into a link that opens it in Coolours (coolours.perpetualsummer.ltd), where the user can preview the swatches, tweak them and export them. Use this whenever you propose a colour scheme, so the user can see it rather than read hex codes. Also returns WCAG contrast ratios for every pair of colours: check them before recommending a text/background pairing (4.5 or more for body text, 3 or more for large text and UI components). Returns each colour's Coolours name: use those names when presenting the palette. Also returns the palette as CSS custom properties: whenever you show CSS, use it exactly as given rather than writing your own. Give the user the URL.

• export_palette unknown never probed

  Export a palette as CSS custom properties or a JavaScript object, with each colour named after its nearest named colour. Output matches Coolours' own Export feature. create_palette_link already returns the CSS; use this for the JS object, or for a palette you didn't create. Use the output as given: its names match the Coolours UI.

• parse_palette_link unknown 43m ago

  Read the colours and name back out of a Coolours link (coolours.perpetualsummer.ltd/create/...). Use this when the user pastes a Coolours URL, for example after editing a palette on the site, so you can apply their changes.
