Overview

Omphalis is where the articles, podcasts, videos, PDFs, and voice notes you choose to keep get structured and connected. This connector brings that Library into Claude, scoped to your own account. What you can do: - Search across everything you've kept, including transcripts, excerpts, and your own notes, then open any item to read its full content. - See an item's Strata (its typed structural moments) and the annotations attached to it. - Follow the Connections Omphalis has found between items in your Library. - Ask a question across several items and get an answer with citations back to the sources. - Save a new link or a note, organize items with Collections, tags, and Spaces, and add notes to your Marks. - Read your notebooks and add to them. You sign in with your Omphalis account and approve the scopes on a consent screen. Claude only sees your own Library, and you can revoke access from Settings in Omphalis at any time. Read tools work on every plan, including free. Saving links, creating Marks, and asking questions across your Library need a paid plan.

Tools

collection_items

ChatGPT
List the Library items grouped within a specified Collection.

collections_create

ChatGPT
Create a new, empty Collection and return its id, which identifies the Collection when filing Library items into it.

collections_list

ChatGPT
List your Collections (your groupings of Library items).

connections_for_item

ChatGPT
List the Connections that link a specified Library item to other items.

connections_list

ChatGPT
List your Connections across the Library, most recently created first.

library_get

ChatGPT
Get a single Library item, including its readable content. Long items are returned in windows: the response includes content_total_length and content_truncated so you can tell whether more of the body remains beyond what was returned.

library_get_structure

ChatGPT
Get the content structure (Strata) for a specified Library item: ordered structural moments with types, labels, positions, and short summaries. These are raw structural entries, so their count can differ from the grouped moments shown in the reader.

library_list

ChatGPT
List your Library items. Defaults to most recently saved first. Use sort_by='longest' or 'shortest' to answer questions like 'what's the longest item in my library' in one call instead of paging through everything. Use offset to page past the first page.

library_organize

ChatGPT
Organize a Library item: add or remove tags, file it in a Collection or a Space, or star it. Everything this does can be undone.

library_save

ChatGPT
Save a new item to your Library from a link: articles, PDFs, YouTube videos, podcasts, and more. Returns the new item's id right away with status 'processing' (the readable content is extracted in the background, so fetch it with library_get a little later) or 'duplicate' if the link was already saved.

marks_add_note

ChatGPT
Attach a personal note to an existing Mark — a system annotation or your own highlight. Use this to record your own thinking on a Mark (e.g. 'this argument seems weak') so it's saved in your Library, not just said in chat. Calling this again on the same Mark replaces its existing note rather than appending to it.

marks_create

ChatGPT
Create a new Mark (annotation) on a specified Library item.

marks_get

ChatGPT
Get the Marks (annotations) attached to a specified Library item, including any note you added to a Mark.

search_library

ChatGPT
Search your Library across item titles, summaries, transcripts, descriptions, excerpts, and notes, and return matching items with a snippet, ordered by relevance.

spaces_list

ChatGPT
List your Spaces. A Space groups Library items; its id narrows a Library listing, a search, or a question to just that Space.

strata_get

ChatGPT
Get the Strata (typed structural moments) for a specified Library item.

tags_list

ChatGPT
List the tags you have applied across your Library, each with the number of items carrying it.
