* feat(mcp): kontoplan account tools + verifikat notes exposure Two gaps reported by an MCP-driven user: no account management in the API, and verifikat notes invisible to agents (they exist in the product but MCP could neither read nor write them). - add staged gnubok_create_account / gnubok_update_account (BAS 2026 prefill for catalog numbers; rename/VAT-default/SRU/activate via update; both LOW risk reference data) - add staged gnubok_set_voucher_note (notes-only annotation, legal on posted entries per the 20260608120000 trigger carve-out) and return entry_notes from gnubok_query_journal - new pending_operations types create_account / update_account / set_voucher_note (CHECK migration + validate companion, applied to staging) - tools/list payload ceiling 54K -> 56K (documented; wire contract, descriptions trimmed first) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(skatteverket): unstick BankID connect flow and stale connection views - respond to the OAuth callback immediately and run the post-connect refresh after the response (next/server after()): users no longer stare at Skatteverket's consumed consent page for up to 40s - open the consent flow in a full tab instead of a 600x750 popup that hid the approve button below the fold - disable connect buttons while the OAuth tab is open (parallel flows overwrote oauth_state + the PKCE verifier) and recover via a closed-tab watcher plus a delayed status refetch - persist MISSING_SCOPE token health from the post-connect sync and show an actionable "approve all permissions" notice - refetch connection state on tab visibility (settings connect panel, enable-banking panel, /skattekonto) so a connect completed in another tab or after a mobile app-switch shows up without a manual reload; fix /skattekonto never clearing its not-connected state Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(article-form): add article number field with validation to ArticleForm * feat(account): enforce account type consistency with BAS class and add validation --------- Co-authored-by: Claude Fable 5 <noreply@anthropic.com>
Accounted MCP server
JSON-RPC 2.0 server exposing the Accounted bookkeeping engine to MCP clients (Claude Desktop, Claude Code, etc.). Endpoint: /api/extensions/ext/mcp-server/mcp. OAuth and stdio bridge live alongside the API surface: see app/api/mcp-oauth/ and packages/gnubok-mcp/.
Tool authoring contract
Enforced by tests in __tests__/: these are not style preferences, they're guard rails.
additionalProperties: falseon everyinputSchema. Guarded bystrict-schemas.test.ts. Forces clear rejections on hallucinated fields instead of silent ignores.- Descriptions ≤ 280 chars. Guarded by
output-schema.test.ts. NoArgs:/Returns:/Examples:prose: those belong in JSON Schema. Use agent-native hints ("Use to…", "Call X first", "HIGH risk"). - Staged-operation envelope for write tools:
outputSchema: STAGED_OPERATION_SCHEMA(server.ts). Fields:staged, risk_level, actor, message, preview, period_status?, next?. Thestaged: trueboolean is the explicit completion signal; agents must not infer completion from prose. Do NOT introduce a parallel{ success, shouldContinue, output }envelope. period_statusthreading: any tool that ties to a fiscal-period-bound date (categorize, mark paid, create voucher, correct/reverse entry, approve supplier invoice) passesdateForPeriodChecktostagePendingOperation. Response then includesperiod_status: { period_id, status: open|locked|closed, lock_date }so widgets and agents disable writes without round-trips.- Scope mapping: every new tool needs an entry in
lib/auth/api-keys.tsTOOL_SCOPE_MAP. Missing entries default to deny. - Tests for new write tools: add staging-gate coverage to
__tests__/voucher-tools.test.ts(or a sibling) plus executor coverage tolib/pending-operations/__tests__/voucher-executors.test.tsif the tool stages a newoperation_type.
Determinism / cache stability
Tool definitions (name, description, inputSchema, outputSchema, annotations) are declared as static object literals at module load: no timestamps, no UUIDs, no Date/Math.random in the definition layer. This makes the tools/list JSON payload byte-stable across requests, which lets agent-side prompt caches stay warm. Do not introduce per-request non-determinism into the definitions block. Anything time-bound or random belongs inside execute().
For internal Anthropic API usage (today only extensions/general/invoice-inbox/lib/extract-invoice-fields.ts): annotate stable prefixes with cache_control: { type: 'ephemeral' } and log usage.cache_read_input_tokens for hit-ratio observability. The 1h TTL from the agent-native API plan (item 10) requires the direct Anthropic API; Accounted's Bedrock path defaults to a shorter TTL.
Payload-size watchdog
payload-size.bench.test.ts enforces a tools/list JSON payload ceiling (currently 36,000 tokens, bumped from 32,000 when top-level Tool.title landed on all tools for Claude Connectors Directory readiness). If the test fires, the right answer is rarely "raise the ceiling". Instead, trim descriptions or leverage gnubok_search_tools (already deployed; tool definitions can defer to it for discovery rather than enumerating in tools/list).
