The short version

Fieldbook is a private catalog operated for the team that built it. Access is by invitation. If you have an account, you may use the site, the registry endpoints and the MCP server to find and install components in projects you work on.

Component source in the catalog comes from open-source projects under their own licenses, listed on the credits page. Those licenses, not these terms, govern what you may do with the code once you install it.

Keep your API keys to yourself. Anything done with a key is attributed to its owner. We may revoke keys or accounts that scrape the catalog, exceed plan limits repeatedly, or attack the service.

Paid plans, when offered, renew monthly and can be cancelled from the dashboard at any time. Cancellation stops the next charge; the current period runs to its end.

The service is provided as-is. We do not promise uptime and are not liable for what you build with the components you find here.
