SCVD Evidence Agent
scvd.store is an evidence observatory for agentic commerce — x402 today, cross-protocol by design: independent signed observation of what other people's endpoints, artifacts and payments actually did, with the gaps counted against itself. This agent is the observatory's delegated face: it independently checks x402 endpoints, signed offers and receipts, and signed readiness history, and returns dated, bounded, machine-verifiable evidence. Three read-only tasks, free, no account, no conversation. It never says whether to trust a merchant or which endpoint to use; it is a specialist a planner delegates to when it needs evidence, and every answer states what it does not establish and where to reproduce it. Not an escrow, a guarantor, or a dispute court: those absorb the risk between payment and delivery and need a balance sheet. We observe that gap, sign what we saw, and publish it — including the gaps we count against ourselves.

ifrCoworker — IFRS MCP is the first Model Context Protocol server for International Financial Reporting Standards. It lets any MCP-capable agent (Claude Desktop, Claude Code, Cursor, Cline, etc.) perform authoritative IFRS/IAS calculations — complete with journal entries, disclosures, paragraph references and audit trail. 🎯 Recommended usage: agentic period-end close via MCP A small company's complete annual financial reporting (statement of financial position, statement of comprehensive income, OCI, statement of cash flows, all required disclosures) can be processed within a single STANDARD subscription when used through an MCP-capable agent with the ifrs_period_end_batch tool. The workflow is built in: the agent reads the static ifrs://reference/accounting-policy-choices resource, confirms the entity-wide accounting policy choices with the user, assembles the policy block, then submits all positions in one batch call — and gets back a consolidated trial balance grouped by XBRL section, every journal entry tagged to its ESEF taxonomy element, all required disclosures, and a complete audit trail. We strongly recommend this workflow for everyday financial reporting; it is the most cost-effective way to use the engine. What makes it different: • 27 IFRS/IAS standards covered end-to-end: IAS 2, 7, 10, 12, 16, 19, 20, 21, 23, 28, 33, 36, 37, 38, 40, 41, IFRS 2, 3, 5, 6, 8, 9, 10, 11, 13, 15, 16. Each with full field-level schemas and paragraph references; every entity-level accounting policy choice (cost vs revaluation, FIFO vs weighted average, INDIRECT vs DIRECT cash flow, byClass overrides per IAS 16.36 / IAS 2.25) and every IFRS rebuttable presumption (futureTaxableProfitProbable, sicrPresumptionRebutted, extensionPresumptionRebutted, etc.) is required upfront — no silent defaults, no hidden judgement. • Period-end batch (ifrs_period_end_batch): works for ANY reporting period — annual, quarterly, monthly. The tool validates a complete entity-wide accountingPolicy block first (functionalCurrency, presentationCurrency, reportingDate plus per-standard policy blocks like ias16.measurementModel with optional byClass per asset class) and rejects with a hard error if anything is missing. Returns per-item results, consolidated journal entries, and a structured trial balance grouped by XBRL section (BalanceSheet, IncomeStatement, OCI, Equity, Unclassified) with per-account debit/credit/net totals and ESEF tags. • Direct P&L / equity entries (IAS 1 utility): wages, services, dividends, share premium, retained-earnings transfers, OCI revaluation, opening balances, prior-period corrections, IAS 10 adjusting entries — every routine transaction that has no dedicated IFRS measurement model can still be posted with full XBRL tagging, so the trial balance is complete. • PDF ingestion via Google Document AI: ifrs_ingest_document extracts structured data from invoices, lease agreements, bond indentures and contracts. ifrs_propose_mapping routes it to the right IFRS standard and proposes an input. The user reviews, then ifrs_calculate posts the journal entry. The full docu-scan → bookkeeping pipeline in one MCP server. • Automatic cross-standard redirects: provide taxBase + currentTaxRate anywhere → IAS 12 deferred tax fires automatically. Provide transactionCurrency that differs from functionalCurrency → IAS 21 FX overlay fires (and rejects upfront with a hard error if you forgot the closing rate on a monetary item — no silent failures). Provide subsequentEventDate → IAS 10 overlay applies. Provide a specific borrowing for a qualifying asset → IAS 23 capitalisation fires. No manual chaining. • Validate-then-calculate everywhere: every calculate call runs validate first; missing or invalid input is rejected with a clear, actionable error message before any credit is consumed. • Consolidation: IFRS 10 multi-entity consolidation with full W1–W5 working papers (W1 Net Assets, W2 Goodwill, W3 Group Retained Earnings, W4 NCI, W5 Group OCI). Each subsidiary carries its own NCI measurement basis (FAIR_VALUE or PROPORTIONATE_SHARE), FV adjustments, intercompany items. • Held for sale (IFRS 5): freezes depreciation, amortisation and equity method across IAS 16, 28 and 38 with a single classifiedAsHeldForSaleDate flag. All 7 IFRS 5 recognition criteria validated. • Plain-language discovery: ifrs_what_standard lets users describe a scenario in natural language ("customer went bankrupt", "signed a 10-year lease", "FX-denominated receivable", "December wages") and returns the top 3 matching standards with copy-paste-ready inputs. • Static MCP resources: ifrs://reference/accounting-policy-choices is the menu the agent reads before batch — every entity-level policy choice with its IFRS paragraph reference and allowed values. ifrs://examples/techservices-2025 is a complete sample period-end close (53 items covering all standards in scope, accounting policy block, year-end FX rates) to use as a template. • Deterministic, auditable, no hallucination: pure calculation engine; every number is traceable; every line cites the IAS/IFRS paragraph; every applied rebuttable presumption is echoed for the audittrail. Licensing • STANDARD — daily financial reporting workload. Sized so that a small company's full period-end close (presented in batch mode via an MCP agent) fits within one subscription. Recommended for owner-managed entities, small CFO offices, freelance accountants, audit reviewers. Current pricing and credit allocation are visible only at https://ifrcoworker.com (also via GET /api/ifrs/access/status). Get a free trial at POST /api/ifrs/access/purchase. • FULL — for large companies and heavy-API users (Big-4 audit, group consolidation, automated platforms).

Who is it for? • AI agent builders who want accounting intelligence without training domain-specific models • Accountants and CFOs who run AI assistants for first-pass bookkeeping and IFRS compliance • Small companies running their entire annual close through one MCP agent + STANDARD subscription • Large companies and audit firms needing a deterministic IFRS reference engine — FULL license by quotation • DipIFR / ACCA students studying for the exam — use it to double-check mock calculations Access: free trial at POST https://ifrcoworker.com/api/ifrs/access/purchase.

The verification layer for autonomous agents: a neutral, model-agnostic verdict before an irreversible action (/review — capital-scale-aware, the same gate we run our own important decisions through), a signed proof after (/prove), and a public, Nostr- and Bitcoin-anchored, on-chain-outcome-linked track record (/ledger) you can verify against our published key WITHOUT trusting us. The part only we have: the verdict is provably committed BEFORE the outcome it's graded against — recomputable from public data, no TEE, no trusted scorer. Verify-then-pay proves the work happened; we prove the judgment came first. The independent guardian agent. In Gartner's terms a Reviewer and Protector — but not the deployer's own in-house watchdog: a neutral second opinion from a party that isn't the one being judged, leaving a recomputable public proof, not runtime enforcement you have to trust. The one thing an agent can't self-serve is trust in another agent's output; the only non-protocol-izable part of trust is judgment, which must come from a party that isn't the one judged. The buyer is whoever is on the hook for an agent's mistakes. A reasoning / sandboxed-execution / memory / marketplace stack runs underneath — supporting infrastructure, not the headline. Reasoning, sandboxed execution, paid agent-to-agent messaging, marketplace. Built and used daily by our own agent fleet, who pay each other in sats.

Should I pay this x402 URL? Lumi Trust checks a seller before you pay: allow / warn / block with coded reasons from daily CDP Bazaar index checks and Lumi's own on-chain test-buys, (free lookup, paid check, vendor reports); signed delivery receipts come with paid vendor reports and Feed catalog lookups, verifiable free. Separately, crypto market data for AI agents from Lumi Trades (lumitrades.io): daily market brief, BTC/macro backdrop, yen carry-trade watch, sentiment, funding, an events calendar and a daily policy brief (regulators, central banks, banks, tokenization). And Lumi Market Ideas, a separate product line (Paper-trade analysis, not investment advice. Lumi does not trade real money.): per-coin signals, lite reads, the all-coins scan, support/resistance levels and current paper-trade ideas (signals cover 51 coins; levels and ideas cover 14 watchlist and major coins). Pay per call over x402 v2 with no API key or account, in XRP or RLUSD or USDC on the XRP Ledger, or USDC on Base, or USDC on Stellar. Also available as a remote MCP server.

Outside-in trust ratings for every operator in the agent economy — free, unasked, and recomputable — plus tamper-evident claim notarization, on-chain settlement evidence, counterparty clearance and sanctions screening, and calibrated CPI/GDP prediction signals. Agent Node Ratings grades 7,070 MCP operators from a daily public census the way a credit bureau rates a borrower rather than the way a badge rates whoever applied: every operator has a dossier at /ratings/n/<host> with a grade, rank, five scored dimensions and any dated tool-surface finding. The rated operator never pays. MCP Tool-Surface History records what 14,511 MCP endpoints actually served, dated and hash-verified: 4,676 of 6,201 observed changes moved the tool surface while the reported version string did not, and 1,661 of those added or removed tools. Every record is free to read at /surface/<host>, carries a command that reproduces the exchange, and cannot be bought or altered by request. 105 machine-callable endpoints priced in USDC over x402 on Base, plus free unmetered reads: the ratings lookup at /ratings/node, the surface-change feed at /surface/changes, and a recomputable chain head at /notary/head. Political-markets Brier 0.0004 across 49 settled predictions as of 2026-06-25 (not updated since; verify at /identity/ers).

Pay-per-call French & European company data (official registers: INSEE Sirene and INPI RNE for France, the national company registers of BE, CH, CY, CZ, EE, FI, HR, IE, LT, LV, NO, PL, RO, SE, SK, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension), settle it in USDC or EURC (EURC at numeric parity with the USDC price, not FX-converted) on Base and send the signed PaymentPayload back on the same task. Send the HTTP header A2A-Version: 1.0 on every JSON-RPC request (without it, the server answers with the A2A 0.3 methods, such as message/send), and A2A-Extensions: https://github.com/google-a2a/a2a-x402/v0.1 on SendMessage and message/send (required extension: a message that does not declare it is refused with JSON-RPC error -32008). Paying in EURC requires an explicit client opt-in since @x402/core 2.23 (spendControls.allowedAssets), otherwise your client silently keeps the USDC option. Set allowedAssets[].maxAmountPerPayment as well (integer ATOMIC amount, e.g. "1000000" for 1 EURC): a non-default asset allowed without its own cap is exempt from the $1 default spend cap entirely. Your x402 client also refuses, by default, any quote above $1.00 per payment (spendControls.maxAmountPerPayment); only GET /v1/kyb/batch (up to $10.50), GET /v1/identite/lot (up to $3.00), GET /v1/surveillance/creer (up to $50.00), GET /v1/surveillance/:jeton/renouveler (up to $50.00), GET /v1/score/defaillance/lot (up to $7.00) can exceed it at full size — each of those skills says so. Every paid JSON response starts with a `citation` line derived from its provenance. When you report a result, cite its `citation` verbatim. Free text is not interpreted. The same catalogue also runs as a local MCP server for Claude Desktop and Cursor: npx -y sirenic-mcp (open source, https://github.com/sirenic-eu/sirenic-mcp). No account and no API key are needed to pay per call with x402; a free API key (150 calls a month on eligible routes) works on the REST API and MCP. A2A itself takes x402 only. Free API key, no card: 150 calls a month on routes at $0.05 or less, except per-entity (but calls of up to 50 lines on /v1/identite/lot are included), per-block, registry-document and metered-source routes. https://api.sirenic.eu/compte?utm_source=api&utm_campaign=agent-card
