api record

KitBench calculators that return exact, deterministic answers: character counting (Japanese-aware), days between dates and adding days (with Japanese business days and holidays), age, Japanese era (wareki) conversion, Japanese consumption tax and unit conversion. Each result includes a "source" link to the matching KitBench page.

_ is it live, free and safe measured by this hub
Is kitbench live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is kitbench free to use?
Not measured yet.
What tools does kitbench have?
7 tools: convert_units, count_characters, days_between, add_days, calculate_age, convert_japanese_era, consumption_tax.
Is kitbench 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.

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.

  • convert_units unknown never probed

    Convert units with official exact factors (NIST etc.), including Japanese units (tsubo, jo/tatami, shaku, sun, go, Japanese cups and spoons), temperature and fuel economy. Returns the exact result, a rounded display value, the factor, and extras such as feet-and-inches, inch fractions (1/16) and pounds-and-ounces. Unit ids by category - length: mm, cm, m, km, in, ft, yd, mi, nmi, shaku, sun; mass: mg, g, kg, t, oz, lb, st, ons, kwintal; temp: c, f, k; volume: ml, l, m3, tsp, tbsp, floz, cup, pt, qt, gal, flozuk, galuk, cupjp, tbspjp, tspjp, go; area: cm2, m2, ha, km2, sqin, sqft, sqyd, ac, sqmi, tsubo, jo, donum; speed: mps, kmh, mph, kn, fps; fuel: kml, l100, mpg, mpguk; pressure: pa, kpa, mpa, bar, psi, atm, mmhg; energy: j, kj, cal, kcal, wh, kwh, btu; power: w, kw, hp, ps; data: b, kb, mb, gb, tb, kib, mib, gib, tib.

  • count_characters unknown never probed

    Count characters in a text exactly as KitBench's character counter does. Counts user-perceived characters (grapheme clusters: emoji sequences, combining marks and flags count as 1), plus counts excluding newlines and whitespace, half-width characters counted as 0.5, lines, paragraphs, Japanese manuscript paper (genkō yōshi, 20x20) sheets, UTF-8 bytes, English words, and a breakdown into hiragana, katakana, kanji, Latin letters, digits and other. Strong for Japanese text and character limits. Text up to 200,000 characters.

_ try it 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 ef27202957233d41.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/ef27202957233d41/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/ef27202957233d41/badge.svg)](https://brick.blue/agent/ef27202957233d41?ref=badge)

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 know
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.
