api record

OpenAccountants: tax skills for 190+ jurisdictions (countries, US states, Canadian provinces). Each skill sets out the method for a tax task, names the official source for its figures, and says whether a licensed accountant has reviewed it.

WHEN TO USE: any question about tax, VAT/GST, US sales tax, payroll or filing for a country or US state, in whatever words the user asks it: 'how much tax will I pay in Spain', 'do I need to register for VAT', 'when is my return due', 'is this deductible', 'how is a freelancer or a company taxed in Germany', 'sales tax in Texas', 'what changes if I move to…

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • get_quote open 35m ago

    Call only when the user asks what OpenAccountants charges, requests a quote, or asks whether their current fee is fair. Returns the same published plans, service prices, limits, market exceptions and hourly rate as the website, plus the engagement process and contact details. Match the client's scope to the listed prices; incomplete scope means the total is provisional. Separately quoted services must be confirmed by OpenAccountants. This tool does not create an engagement.

  • start reads open 35m ago

    Call this first for any tax, VAT/GST, payroll or filing question about a country or US state, such as "how much tax will I pay in Spain", "do I need to register for VAT", "when is my tax return due", "is this deductible", "how is a freelancer or a company taxed in Germany", "sales tax in Texas" or "what changes if I move to Portugal". Pass the user's question as `intent` and the country or US state as `jurisdiction` ('DE', 'US-TX', 'Florida'). If no place is named, start infers one when the question makes it clear and says so in `jurisdiction_source`. Returns the skills to read next (`skills_to_load`, open each with get_skill), or what is still needed, usually the country. Covers 190+ jurisdictions; where no skill exists yet it returns a research_brief naming the official sources. Called with an empty intent (no question yet), it returns the topics and jurisdictions covered.

  • validate_vat_number reads open 20h ago

    Check live whether an EU VAT number is valid and registered, for example before applying a B2B reverse charge, zero-rating an intra-EU sale or onboarding a supplier. Queries the European Commission's VIES registry and returns the verdict plus the registered business name and address where the authority discloses them. Coverage: the 27 EU member states plus 'XI' (Northern Ireland); use 'EL' for Greece. Other countries, including the UK, are not supported yet: say live validation is not available there rather than guessing. If the registry is down the response says so.

  • check_audit_exemption reads open 20h ago

    Answers 'does my company need an audit?' for a private limited company in Malta (MT, Article 185(2) micro thresholds) or the UK (GB, small-company thresholds before and after 6 April 2025). A deterministic check of turnover, balance sheet total and average employees. Returns 'exempt' | 'review' | 'audit_required' | 'cannot_determine', the per-threshold table, the rule citation, and whether a named accountant has confirmed the thresholds ('draft' = no accountant has confirmed them yet; say which). Pass prior_year figures: most regimes are two-consecutive-year tests, so without them a qualifying year returns 'review'. 'cannot_determine' is a valid outcome (unsupported jurisdiction, wrong currency, a shape needing judgment). Use the determination as returned, not thresholds from memory.

  • search_skills reads open 18h ago

    Find or browse skills. With a `query`, finds the skill for a specific tax topic by keyword: a deduction, form, regime or rule such as 'home office deduction', 'Schedule C', 'reverse charge', 'crypto capital gains' or 'Beckham regime'. Without a query, lists the skills for a jurisdiction, domain or role (for example every skill for 'MT', or every 'payroll' skill), each with its current approval label, 100 at a time (limit up to 200; page with offset and next_offset). Optionally limit either to one jurisdiction or domain. Returns skill slugs to open with get_skill. Set content_type='method' to find step-by-step methods (run them via start), each tagged accountant-reviewed or source-cited.

  • search_rules reads open 35m ago

    Look up tax rates, thresholds and rules in one or many jurisdictions, such as 'VAT rates in MT, IE and DE', 'income tax brackets for 2025' or 'rules mentioning reverse charge'. Returns a bundled markdown rule set plus each jurisdiction's official source (`official_source`). For one specific figure in one jurisdiction a skill is often more complete (search_skills then get_skill): a figure can sit in a skill without being a separate rule here, and then this returns related guidance instead. Entries tagged `GUIDANCE` are text, not values. Figures are not certified current: confirm each against `official_source` and prefer it when they disagree. By default returns all matching rules, each tagged with its verification status; status:'verified' excludes draft, needs_update and unsure rules; it still includes research-verified (source-cited) rules, so it does not mean accountant-reviewed. Set `facets: true` to get the valid filter values instead of rules; a call that finds nothing returns `valid_values` for the filter that missed.

  • share_with_openaccountants sends messages unknown never probed

    Only when the user asks: sends their feedback, or their request for a person to check or do the work, to OpenAccountants. Two modes. (1) `note`: an anonymized note about the guidance (a gap, a workaround you needed, or via `skill_slug` a bug in a specific skill). Anonymize hard: no names, amounts, or PII. (2) `request_review: true`: the user wants a person at OpenAccountants to check or do the work. Typical requests: 'can an accountant check this?', 'can someone file this for me?', 'can someone do this for me?', 'I want an accountant', 'can I talk to a person?'. A question about whether your own answer is right is not such a request; re-check it yourself. Also requires `working_paper` (complete), `jurisdiction`, `scenario`, and `contact_email`. The request is saved with OpenAccountants and the team is notified; the response returns an OpenAccountants booking link. The call is free. The work itself is paid: OpenAccountants does it through its accountants, with what is done and the fee agreed on the call before anything starts. Never describe the work itself as free. Call at most once per user request; not as a routine closing step.

  • compute unknown never probed

    Computes a tax figure with fixed, tested code instead of mental arithmetic. Use this for any figure an engine below covers; never compute that figure yourself. Pass only the facts the user gave: the engine applies the tax rules itself (allowances, standard deductions, bands, caps) and never asks you to decide a rule. Returns the result, every step, each rate used with its skill, section and quoted line, the engine's assumptions, skills_used with each skill's approval label (state it exactly as given) and a receipt id. Every engine takes tax_year and refuses a year it has no figures for. Facts marked * are required; an optional fact you leave out takes its default, and the answer states that as an assumption. If the engine returns missing_rule or needs_input, tell the user exactly what is missing or ask them for the fact. Never call again with guessed or altered facts to get a number, and never compute the figure yourself instead.

_ try it over mcp through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 1c4a08466530bd4c.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/1c4a08466530bd4c/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we knowoff the mcp door
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
