83 tools means an agent has many ways to spend, and the $10 pack expires after 90 days whether or not you used it. That is fine for a burst of work and poor for occasional use. The trial is generous enough — 250 credits over 30 days — to find out which of those tools you would actually call before committing to a plan.
Celavii's endpoint. Their tool catalogue page lists 83 tools; the page is a single-page app, so the names were captured as a snapshot rather than parsed into a list here.
83 tools by the vendor's own catalogue. The endpoint requires OAuth before it will enumerate them, so this count is theirs rather than one we obtained.
OAuth bearer, realm celavii-mcp. Credits are the billing unit: Free gives 250 once with a 30-day trial, a $10 pack gives 500 that expire in 90 days, and Starter is $49/month for 3,000.
Paste a URL, then authorize — add the endpoint to your client, then approve the OAuth consent screen
