• list_element_types

  List all 22 OnlyWorlds element types with a one-line shape summary of each. Every world is built from these types; each element has a stable UUID `id`, a `name`, and a `type`. Use `get_element_schema(type)` for a type's full field list…

• get_element_schema

  Return the field structure of one OnlyWorlds element `type` (a slug from `list_element_types`, e.g. "character"). The result groups the type's writable fields by kind so a caller knows how to read and write them: `text` (strings)…

• search_schema

  Search every element type's fields for `query` (case-insensitive substring), across all 22 types. Useful for "which types have a `location` field?" or finding where a concept lives in the schema. Returns a mapping of type slug -> the…

• list_elements

  List elements of one `type` in the world named by your API-Key header, newest-created first. `type` is a slug from `list_element_types` (e.g. "character"). Optional `name_contains` filters by case-insensitive name substring; `supertype`…

• get_element

  Fetch one element by `type` and `id` (a UUID) from the world named by your API-Key header. `type` is a slug from `list_element_types`. Returns the full v2 wire shape (the same body as `GET /api/v2/{type}/{id}`): `type`, `id`, `name`…

• search_elements

  Search elements by name across ALL 22 types in the world named by your API-Key header (case-insensitive substring match). Use this when you know part of a name but not the element's type. Bounded to at most 50 matches per type. Returns…

• get_changes

  Return the delta feed for the world named by your API-Key header: every element created/updated (`op: "upsert"`, full body) or deleted (`op: "delete"`) since `since_cursor`, in apply order, in pages of `limit` (default 25, max 1000)…

• create_element

  Create one new element of `type` in the world named by your API-Key header. `type` is a slug from `list_element_types` (e.g. "character"). `element` is the field payload: `name` plus any scalar, link, or extension fields for that type…

• update_element

  Update an existing element by `type` and `id`, changing ONLY the fields you pass — omitted fields are preserved. This is a server-side read-merge: the current element is loaded and only the keys in `fields` are applied, so it is safe…

• edit_links

  Add and/or remove links on ONE multi-link `field` of an element, leaving the rest of that field's array untouched. Use this for additive/subtractive link edits (unlike `update_element`, which REPLACES a link array). `type` is a slug from…

• bulk_apply

  Create and/or update many elements across any of the 22 types in one call. Each entry in `items` is `{"type": <slug>, "element": <payload>}` with the same payload shape `create_element` takes: an `element` with an `id` UPDATES that id…

• get_image_upload_ticket

  Get a ticket to upload ONE image into this world, for an element's `image_url` (Keel #59). The image never passes through this tool: you send its bytes yourself, straight to the image host, with the ticket. Steps: 1. Call this tool. You…
