Is yarrow live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is yarrow free to use?

Yes — the hub reached it with no key and no payment.

What tools does yarrow have?

7 tools: two_lenses, cast_hexagram, cast_tarot, divine, tarot_reading, lookup_yilin, lookup_hexagram.

Is yarrow 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.

• two_lenses reads unknown never probed

  Bring one real question to two independent symbolic traditions: a source-first I-Ching cast and one upright Waite-Smith Major Arcana card. Returns a clear calibrated answer first, then five grounded sections covering the I Ching lens, Tarot lens, shared themes, different emphasis, and next step. Direction without guaranteed prediction or mutual-confirmation claims. Daily quota is shared with completed divine readings.

• cast_hexagram reads unknown never probed

  Cast a hexagram for an I-Ching consultation. Returns the primary hexagram, the six lines (6=old yin, 7=young yang, 8=young yin, 9=old yang from bottom to top), any moving lines, and the changing hexagram if there are moving lines. Pass `seed` to make the cast deterministic (useful for testing or for reproducing a reading).

• cast_tarot reads unknown never probed

  Draw one upright Major Arcana card for reflection. Uses a deterministic one-card Waite-Smith Major Arcana method and returns a selected source excerpt from Arthur Edward Waite's public-domain 1910/1922 text. Pass `seed` to reproduce the same draw.

• divine reads unknown never probed

  Ask the I Ching. See your next step. Cast a hexagram, show the classical sources first, then offer a thoughtful reflection grounded in those sources. Sources first. Reflection, not prediction. The divine name remains stable for oracle/divination client compatibility. Supports English, Chinese, Japanese, Korean, Spanish, French, German, Portuguese, Italian, Russian, Arabic, Hindi, Indonesian, and English+Chinese bilingual output. Daily quota: 30 completed readings per device_id (or per anonymous IP if no device_id is supplied); timeout, provider failure, incomplete response, and cancellation do not consume it.

• tarot_reading reads unknown never probed

  Ask one real question through a single upright Waite-Smith Major Arcana card. Returns a direct calibrated answer first, the named card and bound Arthur Edward Waite 1910 source excerpt, a practical reality check, and one observable next step. No reversals, astrology, redraw loop, or guaranteed prediction. Daily quota is shared with completed divine and Two Lenses readings.
