Domains

Grouping collections, and views that read across them.

7 tools — 4 read, 3 write.

Tool		What it does
create_domain	write	Create a domain — a named grouping of collections (e.g.
delete_domain	write	Delete a domain.
export_domain_view	read	Export a SAVED domain (spine) view as a CSV snapshot: the view's own filters, column selection and column order, every row it resolves to.
list_domains	read	List the domains (collection groupings) you can see in this organization, with how many collections each groups.
modify_domain	write	Rename a domain and/or set its description.
preview_domain_view	read	Render an UNSAVED domain (spine) view config without persisting it: one row per item in the config's anchor collection, one column per relation path walked out from it.
resolve_domain_view	read	Render a domain (spine) view: one row per item in the view's anchor collection, plus one column per relation path walked out from it.

Calling these

Over MCP, find one with search_tools, then run it with execute_tool. Over REST, POST /api/capabilities/<tool> with the arguments as the JSON body. Either way, fetch the input schema for the tool you're about to call rather than guessing — get_tool_schema over MCP, or GET /api/capabilities?name=<tool> over REST.

See How the API works for auth, errors and the shared envelope.
