Claude Custom Connector

Add Betterness or Betterness One to Claude on the web, desktop and mobile.

What you need

A Claude plan with custom connectors: Free (one custom connector), Pro, Max, Team or Enterprise.
A Betterness account. For Betterness One, a Betterness One workspace.

Server URLs

Connector name	URL
`Betterness`	`https://api.betterness.ai/mcp`
`Betterness One`	`https://api.betterness.one/mcp`

They are two connectors. Add the one you need, or both.

Free, Pro and Max

Open Settings → Customize → Connectors.
Select + Add, then Add custom connector.
Enter the name and the URL from the table, and select Continue.
Keep the authentication Claude detects and select Continue. Under Authentication, choose Sign in now. Under OAuth client, keep Use Claude's published identity (Recommended). Leave Request headers empty.
Select Add. Claude opens the Betterness sign-in page at auth.betterness.ai.
Sign in.
Accept the permissions on the consent screen.

Team and Enterprise

An Owner adds the connector once for the organization; each member then signs in with their own Betterness account.

Owner: open Organization settings → Connectors, select Add, hover over Custom and select Web. Enter the name and the URL, then follow steps 4 and 5 above.
Each member: open Settings → Customize → Connectors, find the connector (it carries a Custom label) and select Connect. Sign in and accept the permissions.

Do not put a bk_* or bko_* key in Request headers on a Team or Enterprise connector: every member would act as the key's owner.

Use it in a chat

Select + at the lower left of the chat, then Connectors, and turn Betterness on for the conversation. Then ask, for example, "How did I sleep this week?" or, for Betterness One, "Which of my Instagram posts did best last month?"

Purchases, appointments, Inbox messages and posts show you a preview first and run only after you approve it in the chat.

With an API key instead of signing in

For a personal connector only: under Authentication choose No sign in, and under Request headers add Authorization with the value Bearer bk_... (Betterness) or Bearer bko_... (Betterness One). Signing in is better: the access can be disconnected from Betterness and holds only the permissions you accepted.

Remove it

In Settings → Customize → Connectors (or Organization settings → Connectors for Owners), select the three dots next to the connector and Remove. To withdraw access from the Betterness side as well, disconnect Claude in Connected apps.
