One credit covers a turn of conversation with the Studio Copilot. Free includes 5/month; Pro and Teams include 5 plus an option to buy more.
Is MCP serving billable today?
No. Every public Hub version has a live endpoint at mcp.ontoboom.com/o/@ns/slug@ver with no usage meter.
Can I serve a private ontology over MCP today?
No — private ontologies return 403 from the MCP endpoint. Public + unlisted ontologies serve to anyone.
Is there a free trial for Pro or Teams?
No free trial — the Free plan is the trial. You can publish public Hub ontologies, design with the visual canvas, and run real validation on Free. Upgrade when you need unlimited projects, private publishing, or team collaboration.
Do I need a paid plan to publish to Hub?
No. Public publishing is free, including the live MCP endpoint. Paid plans add private + unlisted publishing and bring private MCP access.
Can I self-host the MCP server?
Yes — for enterprise. Get in touch and we'll send you the on-prem packaging path.
