From the fourth E2E run: the agent correctly refused to reproduce a 104 KB SIE file token by token (silent mid-verifikat truncation) and dead-ended to the web wizard, and its replies were walls of compliance prose. 1. gnubok_create_sie_upload: signed same-origin upload URL (reuses the pending-document infra; .se/.sie/.si only, 50 MB HTTP cap). gnubok_sie_preflight and gnubok_import_sie accept upload_id as the byte-exact source, plus optional sha256 (hex of the raw bytes) verified on the upload_id/base64 paths so truncation is DETECTED, never silent. Inline content above 120k chars is refused with a pointer to the upload flow. Scope bookkeeping:write (same intent as import_sie). 2. Skill: brevity rule (max ~8 short lines per reply, one warning per step, no legal essays), memory-first rule (check what is already known before asking the opening questions), the upload-first SIE step, and gnubok_explain_voucher_gap after import for skipped voucher numbers. 3. CONNECTORS.md starter prompt rewritten memory-first so it stays copy-paste ready without the user's own data in it. Plugin v1.2.2. tools/list ceiling 62K to 62.4K documented in the bench.

Connectors
This plugin bundles exactly one connector: the Accounted MCP server, the same server that backs the Accounted connector in Claude.ai and the accounted-mcp stdio bridge.
| Connector | Server | Auth | What it reaches |
|---|---|---|---|
| Accounted | https://app.accounted.se/api/extensions/ext/mcp-server/mcp?tool_namespace=accounted |
OAuth 2.1 (PKCE). One-click consent: all scopes pre-selected (adjustable in a fold); every write still stages for explicit approval before it touches the ledger. | The user's own companies in Accounted: ledger, transactions, invoices, VAT, payroll, reconciliation, year-end. |
Share link and starter prompt
One-click add on claude.ai (opens the Add custom connector dialog prefilled; the params are connectorName/connectorUrl):
https://claude.ai/customize/connectors?modal=add-custom-connector&connectorName=Accounted&connectorUrl=https%3A%2F%2Fapp.accounted.se%2Fapi%2Fextensions%2Fext%2Fmcp-server%2Fmcp%3Ftool_namespace%3Daccounted
Pair the link with a starter prompt the user pastes as their first message. It stays copy-paste ready for everyone because it points the agent at what it already knows (Claude memory, earlier chats) instead of containing the user's own data; the server-side onboarding skill carries the rest of the flow:
Sätt upp mitt företag i Accounted. Utgå från det du redan vet om mig och mitt bolag (organisationsnummer, bank, tidigare bokföringssystem) och fråga bara efter det som saknas. Håll det kort.
How the connection works
- Lazy authentication. The server answers
initialize,tools/listand 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:setupwalks 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_operationor 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.
Self-hosted Accounted
Point the plugin at your own instance: remove the bundled server and add yours with claude mcp add --transport http accounted "https://your-host/api/extensions/ext/mcp-server/mcp?tool_namespace=accounted". The same OAuth flow, skills and commands apply.
