list_topics
List all topics accessible to the authenticated user. Returns topic metadata including id, name, description, and tenant.
LABSCO SUMMARY
Three snippet types is a small piece of design that keeps a research library usable.
A bookmark, your summary of the page, and a thought with no source are genuinely different things, and tools that flatten them into one note type produce a pile nobody revisits. Keeping them apart at the API means an agent filing research preserves that distinction automatically. One caution worth stating plainly: send_notification reaches colleagues over Slack and email, so an agent with this connection can message people, not just take notes.
What it is
Cluing's hosted server for its research workspace, nine tools in all. Its unit is a snippet inside a topic, in three kinds: bookmark, summary and idea.
What you get
- list_topics and get_topic — topics with their non-archived snippets and role information
- create_bookmark, create_summary, create_idea — a page you saved, your write-up of it, or a free-form note with no source URL
- create_topic — a new topic, optionally inside an existing cluster
- create_smart_document — a full Markdown document, readable and searchable in Cluing
- list_workspace_users and send_notification — notify colleagues over the in-app inbox, email or Slack
Requirements
A Cluing account. You add the connector in your client and sign in to Cluing over OAuth, choosing which permissions it gets; the tool list is visible without signing in, but every call needs that sign-in.
Setup effort
Paste a URL, then authorize — add the endpoint to your client, then approve the OAuth consent screen
USE CASES
01
Filing research as you read
Save the page as a bookmark and your own distilled write-up as a summary, both under the right topic.
02
Capturing a thought with no source
An idea snippet needs no URL, so half-formed notes have somewhere to go.
03
Writing something longer
Create a Smart Document in Markdown that stays searchable in the reader.
04
Telling a colleague
List who can be notified, then send over inbox, email or Slack — remember this reaches real people.
9 tools
Counted once with only startup setup. Other versions, modes or optional credentials may expose a different list.
get_topic
Fetch a single topic by its ID, including all non-archived snippets and role information.
create_summary
Create a SUMMARY snippet (the user's distilled write-up of a web page). Requires url + content. Content must be HTML, not Markdown.
create_bookmark
Create a BOOKMARK snippet for a web page. Requires url + content. Content must be HTML, not Markdown.
create_idea
Create an IDEA snippet — a free-form note that does not need a source URL. Requires content. Content must be HTML, not Markdown.
create_topic
Create a new Topic in the user's workspace. Requires name. Optionally place inside an existing cluster.
create_smart_document
Create a Smart Document — a full Markdown document readable in the Cluing reader and searchable by AI. Use for anything longer than a snippet: reports, drafts, guides, articles. Requires name + markdown.
list_workspace_users
List the people in the workspace who can be notified. Returns {userId, name, email, isSelf, availableChannels} per member. Call this before send_notification to resolve names to user ids — never guess a userId.
send_notification
Send a notification to one or more workspace members over the in-app inbox, email and/or Slack. Optionally link a Cluing entity to make it clickable. Write title and message as plain prose with NO Markdown — none of these channels render it, so bold, headings, bullets, backticks and [text](url) arrive as literal characters; link the entity instead of writing a Markdown link. Returns a per-recipient, per-channel status — report anything that is not SENT instead of retrying.
