Notion, Linear, Atlassian, Sentry, Asana and Stripe no longer open the
MCP server form. The wizard shows one "Sign in to Notion" button: the
pop-up opens inside the click (so browsers allow it), follows the
worker's mcp.oauth events to the provider, and the tool is saved on
success with its actions on the done step. Reconnecting a preset uses
the same flow, as do the chat bar and the health toast.
Saving an OAuth MCP server without a new handshake now uses the stored
sign-in instead of failing, and the custom MCP form keeps scopes and
timeout under Show advanced.
- Guides > Connectors: using connections, sharing modes, attribution,
and admin setup (encryption key and rotation, redirect URIs, Google
Drive, SharePoint, Confluence, S3, MCP presets).
- Integration pages register CONNECTOR_REDIRECT_BASE_URI as-is; the
?provider= suffix never matched what the backend sends.
VITE_GOOGLE_CLIENT_ID is optional.
- Upgrading: set ENCRYPTION_SECRET_KEY before migrating multi-user installs.
