mearef
Registry code: cd4c3f98de409bc9
Paid answer tools (check_minimum_wage, compute_vat, count_working_days, settlement_date, compute_income_tax, compute_statutory_interest, compute_employment_cost) take optional receipt, a boolean that defaults to false. When receipt is true, a paid success embeds an Ed25519 answer receipt (kind answer_receipt). The receipt is included in the answer price — no extra USDC. HTTP 402 and free refusals do not include a receipt. An answer receipt is not a series certified extract and is not legal advice. It only covers the computation over the cited series as of last_confirmed. Series certified…

- Is mearef live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is mearef free to use?
- Partly — some of its tools are open, others need a key or payment.
- What tools does mearef have?
- 13 tools: Change and freshness feed, Series history, List available series, Compare across countries, Public holidays, Get a reference value, Regional snapshot, Country brief, ….
- Is mearef safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address also stands behind 7 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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_changes reads unknown never probed
Free, unmetered feed of series whose current value moved, plus how recently the served set was re-verified. Poll this instead of re-buying a series.
get_series_history reads unknown never probed
Historical values for a series over a date range
list_series reads unknown never probed
Catalog of 12 series types across 9 Middle Eastern countries
compare_series unknown never probed
One series across up to 10 countries in one call, each row cited
get_public_holidays reads unknown never probed
Official public holidays for a country and year
get_series reads unknown never probed
One cited reference value (policy rate, VAT, minimum wage, CPI, corporate or personal income tax) with source URL and effective date
get_snapshot reads unknown never probed
Every current series value for every country in the region
get_country_brief unknown never probed
Every series for one country in one call, each cited
vat_determine unknown never probed
For a seller making a cross-border digital sale: which jurisdiction's VAT applies, who accounts for it, the registration trigger and rate basis — each cited to the statute (EU, UK & South Africa; defined supply pairs). Handles the wallet-only, unidentified-buyer case that x402 settlements produce.
compute_statutory_interest reads unknown never probed
Simple interest on a principal at the cited statutory-interest series rate (Actual/365). A series with no numeric rate is refused free. Optional receipt:true on the paid HTTP 200, included in this answer's price. Verify with verify_answer_receipt (free).
get_calendar reads unknown never probed
Free, unmetered re-verification window for this brand. reverify_by is derived from last_confirmed + update_cycle_days. status unknown omits any next date. Notes are not parsed. Not an MPC, budget, or wage-review date.
verify_answer_receipt reads unknown never probed
Free check of an answer receipt (kind answer_receipt) against the public key at /certified/public-key. Confirms this service signed that receipt. Not a series certified extract and not legal advice.
validate_tax_id unknown never probed
Format and (where published) official check-digit validation of a tax ID or VAT number: valid/invalid, normalised form, id type, failure reason, cited
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.
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.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - 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. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idcd4c3f98de409bc9.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/cd4c3f98de409bc9/claim.

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.
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.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
