* feat(mcp): ledger-context resource with per-company booking patterns Adds Accounted://ledger/context: derived account usage, counterparty booking patterns with explicit confidence share (0.7 floor), explicit mapping rules kept separate as authoritative, observed VAT profile, and conventions. Backed by a SECURITY INVOKER get_ledger_usage_stats RPC so group-bys run SQL-side, and surfaced as a top-5 digest stanza on gnubok_get_agent_briefing so one call still bootstraps a session. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> * feat(mcp): fold source-quality prereqs into the ledger-context RPC Merchant-name normalization at the aggregation path (the splinter fix): new normalize_counterparty_key() SQL function mirroring normalizeCounterpartyName() so KORTKÖP/SWISH/date-suffixed labels merge into one counterparty key, which also makes the categorization_templates join exact. New supplier_patterns section (per-supplier dominant expense account + VAT treatment from supplier invoices; credit notes and reversed invoices excluded). account_usage excludes storno lines (they re-inflate the account a correction moved away from); the counterparty CTE keeps corrections because the transaction relink self-heals. Pattern confidence is now count-grounded evidence {seen_12m, agree, share, last_booked} instead of a bare ratio, and the digest frames it as historical frequency, never auto-book permission. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(agent-context): use roundOre for the share ratio (antipattern ratchet) Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(agent-context): defensive storno filter on counterparty CTE, fail-loud secondary reads Review follow-ups: the counterparty CTE now excludes source_type='storno' defensively (no live code path links a transaction to a storno, but legacy rows may predate reverseEntry's unlink; a linked storno would count the reversed category as precedent). Corrections stay included: they are the live booking after relink. Secondary reads (rules, templates, settings) now throw instead of silently reading as empty data: an agent must never be told 'no rules' when the truth is 'read failed'.

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).
