* fix(mcp): offer the link tool in the uncategorized-transactions VAT blocker The gnubok_vat_close_check blocker hint only named categorize/auto-match, both of which create new bookkeeping. For a transaction whose affarshandelse is already booked on an existing verifikat, following the hint would double-book, so agents dead-ended the case into "contact support" (2026-08-06 support mail from Orto Engineering). The hint now also names gnubok_link_transaction_to_journal_entry, is extracted as an exported constant pinned by a test, and the tool joins the categorize_month recommended loadout. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * feat(invoices): quarterly, half-yearly and yearly recurring schedules User request: recurring invoice schedules only supported monthly cadence. Adds interval_months (SMALLINT 1-12, default 1) to recurring_invoice_schedules; the UI offers manadsvis/kvartalsvis/ halvarsvis/arsvis presets while API and MCP accept any 1-12. The cron advances next_run_date by whole intervals from the due date, and the new rollNextRunDateForward() helper rolls missed or edited interval schedules on their own month grid so a quarterly Jan/Apr/Jul/Oct schedule missed in an outage rolls Jan 15 to Apr 15, never Feb 15. Monthly (interval 1) keeps its existing today-anchored recompute semantics unchanged. Changing the interval alone never touches next_run_date: the new cadence applies from the next run, so an edit can never pull a send earlier. Existing rows default to 1 and behave byte-identically. The MCP slice of this feature (interval_months on the three recurring-schedule tools in server.ts) was committed in d2600907f alongside the VAT-blocker hint fix by a parallel session sharing this worktree. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(invoices): address PR #1438 review findings CodeRabbit round 1, all three findings: - MCP descriptions now state the full accepted interval range (any integer 1-12) instead of enumerating only the 1/3/6/12 presets, and qualify that changing ONLY interval_months leaves next_run_date untouched. - assertValidCadence rejects fractional day_of_month. - rollNextRunDateForward rejects calendar-invalid anchors that pass the shape regex (2026-13-05, 2026-02-31), with regression tests.

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.
