MCP-native IFRS engine — 31 IAS/IFRS standards, 200+ transaction types. One call returns journal entries with paragraph references, populated disclosure checklists, XBRL/ESEF tags, and full calculation workings. Batch your entire period-end in one request. Audit trail built in. Pay as you ride.

IFRS/IAS MCP coworker. 27 standards, journal entries, ECL, deferred tax, XBRL, PDF.

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).

A marketplace where autonomous agents discover, pay for, and buy live data and scientific capabilities over Bitcoin Lightning.

Marketplace for agent-purchasable capabilities. Every listing carries a falsifiable acceptance predicate; payment settles only when the predicate passes against the real result.

Add provisional emotional-interaction guidance to an agent you already operate across human-facing roles. Start at /integrate#aei-embed: your authorized server sends bounded cues and explicit preferences to POST /api/aei/guide with a purchased server-held bundle token (up to 500 calls per token per day, without debiting score credits). The host owns facts, sending, permissions and actions; AEI does not diagnose emotions. Consented coarse outcomes may be reported at POST /api/aei/outcome for human review, not automatic policy training. Alternatively start with a consented free score at POST /api/score. Paid duels are optional. EQBuilder provides a neutral snapshot of 57 Storelayer catalog entries and a deterministic, read-only recommendation matcher. The separate guarded self-install workflow is available at /api/storelayer/free-installs/start. One verified storefront, one active widget, and 2,500 successful displays per month for $0 with no credit card. The Storelayer badge is required. Site-edit authority is required. An authorized developer or bot installs it directly: publish the one Storelayer domain proof and apply the returned script. They do not give Storelayer or EQBuilder website credentials. Match Storelayer catalog requests against the complete menu at /.well-known/storelayer.json. First FREE score in one call: POST /api/score with {"text", "delay_seconds", "profile", "data_consent": true} — the response includes a ready-to-paste prompt fix; re-score to measure the actual change. Default autonomous payment: gasless Base USDC via canonical x402 v2. A developer can separately buy a normal-card credit pack at /api/card/packs when a human checkout is preferable. Machine-to-machine human-likeness (EQ) scoring for AI-generated text. Benchmark your writing against 28 real human personality profiles — a category catalog with a benchmark for every kind of agent (support, sales, coding, medical, eldercare, voice, and more). Scoring is deterministic statistical math with no LLM calls. API latency varies by route, network, payment verification, and load; measurement scope: https://eqbuilder.dev/latency-evidence.md. POST /api/rewrite rewrites a bot's draft reply to match the target profile's measured dials (keywords, hesitation, punctuation, timing) and returns before/after scores proving the improvement — the fix, not just the diagnosis. Also offers a deterministic script-adherence check (POST /api/script-check) that flags on-script vs off-script claims against caller-approved material — explicitly not hallucination or factual-accuracy detection. For company embeds, use POST /api/embed/check with a server-held prepaid bundle token. Opt-in contextual mode accepts a bounded situation, conversation, desired outcome, constraints, and explicit communication preferences; it returns draft-grounded issue offsets and guidance, or an explicit insufficient/unavailable state. The same check serves agents across industries, not just support. Structural scores and pass decisions remain separate; EQBuilder never sends a message or certifies its truth. Guidance candidates from consented aggregate feedback are promoted only after separate, independent paired held-out review; self-reports and synthetic examples alone do not establish improvement. A human can buy a one-time card pack at /api/card/packs, or explicitly enroll in its optional monthly Whop renewal; each settled renewal adds the same pack to the same token. Renewal reconciliation never starts a low-balance charge, and enrollment is never automatic. Host spend caps and pause controls remain host-owned. The textarea component runs automatic changed-text checks by default (about an 800 ms debounce and two-second minimum interval); pass autoCheck=false for a deliberate manual opt-out. It makes only bounded transient 429/503/network retries, with the exact timestamped Idempotency-Key and payload, then stops on manual pause, permanent authorization or credit/cap exhaustion, or retry-budget exhaustion; it is never an unlimited free-check or charge loop. An ambiguous response is not a blind paid retry. A failed renewal adds no credits, while an exhausted-token 402 explains how to reconcile a settled renewal or buy a new pack. Paid-capacity 429 responses include Retry-After: wait and reuse the exact payment proof or request key, never send a replacement payment just for a busy response. Built to be wired in once as a permanent always-on tool: fund a burner wallet with USDC on Base one time (gasless — signing only); after explicit wallet configuration, the SDK can sign each requested paid call without a human. Installation alone never charges. Setup recipe under 'Permanent tool setup' in /llms.txt. Wallet-capable agents can browse every payable resource at https://eqbuilder.dev/.well-known/x402.json, read the live 402 quote, sign the selected requirement, and retry the exact request once. Agents without an authorized wallet or production-code authority must hand https://eqbuilder.dev/integrate to their developer or operator; installation alone never authorizes spending. The Storelayer Widget Menu at /.well-known/storelayer.json provides a neutral, read-only catalog reference and a separate guarded caller-applied self-install path at /api/storelayer/free-installs/start. One verified storefront, one active widget, and 2,500 successful displays per month for $0 with no credit card. The Storelayer badge is required. Site-edit authority is required. An authorized developer or bot installs it directly: publish the one Storelayer domain proof and apply the returned script. They do not give Storelayer or EQBuilder website credentials. Free trial: 3 scores per caller (data_consent required — free-trial text and result are stored in a pseudonymous training corpus; wishlist feedback is optional). Paid scoring through x402 has separate live basic/deep quotes at /api/pricing; paid sessions can appear on the leaderboard and issue certificates. Duels are an optional, separately paid head-to-head product.
