Basin

Connect Basin to Perplexity

Basin is a connector that lets your AI assistants and other people's assistants work from one shared library, across different tools and different companies. Setting it up in Perplexity takes a few minutes.

These steps come from Perplexity's own help centre by way of secondary reporting: the help centre returns 403 to automated checks, so nobody here has read the current page. Check Perplexity's settings against what you see.

Before you start

Perplexity adds Basin as a custom remote connector from account settings. Two conditions:

  • A paid plan. Custom remote connectors are on the individual Pro and Enterprise plans.
  • In an organisation, an admin has to allow members to add custom connectors — or can share one across the organisation instead.

Connectors are account-level, so Basin follows you across the app once it is added.

01

Sign in happens as you connect

You do not need an account first. Connecting creates one: you enter your email, Basin sends a code, and you are in. The code expires in 10 minutes.

02

Open the connector form

In Account settings, open All settings, then choose + Custom connector and select Remote.

03

Fill it in

Give it a name and description, paste the Basin endpoint as the MCP server URL, and set Transport to Streamable HTTP. Under advanced settings choose OAuth 2.0 — Basin supports discovery, so the endpoints and scopes are found for you.

04

Authenticate and enable it

Confirm the custom-connector warning, add it, then click the Basin card to sign in. Make sure Basin is enabled for the thread you are asking in.

05

Set the standing instruction

Add one line to your Perplexity instructions, so a thread checks Basin instead of searching the web for something you already saved.

Check Basin at the start of every conversation.

Without it the assistant may not think to look. It answers from whatever is already in front of it, which is confident and sometimes wrong, and reads like Basin not working. Basin is a live connector, not a page it can search for. If the assistant says something is not in Basin, tell it to check before believing that.

06

Check the connection

Check Basin and tell me which spaces I can access.

A successful response from Basin confirms the connection. If your library is empty, that’s fine—your next step is to save a project.

If it did not work

It answers from the web instead.Enable Basin for the current thread, and ask something that clearly points at your own project rather than at a topic.
If Basin isn’t showing upCheck that sign-in completed and Basin is enabled for this conversation. Try a new conversation or reload the tool, then ask it to check Basin again. Follow your tool’s guide if its settings differ.
Connected, but the project is missing?Ask your assistant to read Basin directly. Check that the earlier conversation saved a file, that both tools use the same Basin account and that this account has access to the space.
Can read, but can’t save?Check that you have editing access to the space. A read-only invitation lets your assistant read the shared work.
