* feat(mcp): accept article_id on gnubok_create_invoice lines Invoice lines staged via MCP can now reference a catalog article (artikelregister). Staging prefills description, unit, unit_price, vat_rate and revenue account from the article with explicit-wins semantics, mirroring the web line picker. Unknown, foreign-company and deactivated articles are refused at staging, as is a price prefill from an article priced in another currency. The approval executor gains a company-scope gate for staged article_id values: the FK on invoice_items.article_id proves existence, not tenancy. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(mcp): adopt article VAT rate only from the customer's default set Web line picker parity (InvoiceEditor's applyArticle guard): an article's stored vat_rate is its domestic rate. The prefill previously staged it unconditionally, and the staging/commit gates check the wider permitted set (which includes 25/12/6 for taxed-where-performed supplies), so {article_id, quantity} to a validated EU business staged 25% Swedish VAT onto a reverse-charge invoice. The customer is now fetched before the prefill and the article rate is adopted only when it is in the customer's default rate set; foreign-business lines fall back to the 0% reverse-charge/export default unless the agent sets vat_rate explicitly. Prefill logic extracted into resolveInvoiceLineFromArticle (CodeRabbit). Found by the skeptic review pass (two independent refutations) and the Swedish accounting compliance bot, all converging on the same defect. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(invoices): name the article VAT adoption set in vat-rules, not the MCP server The vat-rate-gate-parity guard pins that no invoice write path mentions getAvailableVatRates: gating on the picker default is the bug it exists to prevent. The article-rate adoption in gnubok_create_invoice needs the default set for a different purpose (prefill, not gating), so the semantics move into lib/invoices/vat-rules.ts as getArticleVatRateAdoptionSet(), with tests pinning that adoption is empty for single-rate foreign customers and always a subset of the permitted set. server.ts keeps gating on getPermittedVatRates.

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. Add ?tool_namespace=accounted for the Accounted tool names. Requests without it retain the legacy Gnubok namespace. OAuth and stdio bridges live alongside the API surface: see app/api/mcp-oauth/, packages/accounted-mcp/, and the compatibility package in 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. If the test fires, the right answer is rarely "raise the ceiling". Instead, trim descriptions or set specialized wide tools to catalogVisibility: 'search'. Those tools remain discoverable with full schemas through gnubok_search_tools and callable through tools/call without bloating the default catalog.
