+- **Lazy authentication.** The server answers `initialize`, `tools/list` and the documentation tools (`accounted_search_tools`, `accounted_list_skills`, `accounted_load_skill`) without any credentials. The first company-scoped call returns an authentication challenge, which Claude Code surfaces as `/mcp` → authenticate and Claude.ai as an inline Connect prompt.
+- **Adding it by hand in Claude.ai** (Settings → Connectors → Add custom connector): choose Authentication **"Required when the server asks"** (not the auto-detected "None") and OAuth client **"register one automatically" (DCR)**; the server does not advertise CIMD yet. No extra headers, Streamable HTTP.
 - **Account creation inside the sign-in.** A user who has no Accounted account creates one on the sign-in screen the challenge opens (BankID or e-mail + 2FA). No visit to the website first. `/accounted:setup` walks the whole flow, including creating the company from the conversation.
 - **Every write is staged.** Write tools create a pending operation with a preview; nothing is booked until the user approves, either in chat via `accounted_approve_pending_operation` or in the web app.
 - **Data stays in the user's tenant.** The connector only ever sees companies the signed-in user is a member of, enforced server-side per call.
