Connect Basin to Claude

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 Claude takes a few minutes.

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.

Add the connector

Add Basin as a custom connector in Claude's settings and paste the endpoint. On Free, Pro, and Max you add it yourself; Free allows one custom connector. On Team and Enterprise an Owner adds it for the organisation, then each member connects with their own account.

When you connect, Basin asks for two things: read access to the spaces you own and the ones shared with you, and write access to files in those spaces, stamped with your email. Connecting shares nothing with anyone else. Sharing is always a separate step.

Once connected, Basin works in Claude on the web, Desktop, Cowork and mobile.

Start a new conversation

Start a new conversation after you connect. Claude loads a connector's tools when a conversation begins, not partway through one. A chat that was already open will not see Basin.

Set the standing instruction

Add one line wherever Claude keeps standing instructions: your custom instructions, a project's instructions, or CLAUDE.md if you use Claude Code.

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 project or a document sitting in the chat. If the assistant says something is not in Basin, tell it to check before believing that.

Verify

Ask for something that needs a real read:

What is in my Basin library?

If it names your spaces, it is working.

If it did not work

No Basin tools at all.This conversation is not connected. Start a new one. A Claude Project conversation shows zero Basin tools even when the connector is on, so use an ordinary chat.

Fewer than 17 tools.Claude is holding an old tool list. Remove Basin and add it again. Basin serves 17 tools; fewer means the list is stale.

The tools are there but the assistant never uses them.The standing instruction above is missing, or Claude is holding the tool details behind a search. Add the line, or set Basin's tool access to “always available”. This one does not look like a connection problem, which is why it is the common one.
