api record

Acorn Harness (https://acornharness.com) builds custom XT30, XT30(2+2) and XT30 + JST GH wire harnesses to order. They are Assembled in the USA, 100% tested, and ship within 5 business days (US only).

_ is it live, free and safe measured by this hub
Is acorn-harness live?
Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.
Is acorn-harness free to use?
Yes — the hub reached it with no key and no payment.
What tools does acorn-harness have?
4 tools: create_order, get_order_status, quote_harness, list_options.
Is acorn-harness 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.

  • list_options open 1h ago

    List every option for an Acorn Harness custom wire harness: connector types (XT30, XT30(2+2), XT30 + JST GH), wire length range, power gauges, end terminations (straight, right angle up/down, unterminated tinned leads), wire colors, extras (twisted or crossed signal pair, JST GH end B), the rules for combining them, the defaults, pricing rules, lead time, shipping and returns. Call it when you need the allowed values; it takes no arguments and changes nothing.

  • create_order unknown never probed

    Create an unpaid order for one or more wire harness designs and get a checkout_url on acornharness.com for the buyer. The buyer opens it to pay (card, Link or wallet, via Stripe) and enter the US shipping address and shipping speed; nothing is charged or built until they pay there, and the link expires after 24 hours. Quote first with quote_harness and confirm the design, quantity and price with the user before calling this. Never ask for or accept card numbers or other payment details in the conversation. Items take the same fields as quote_harness.

    Check an order by the id create_order returned (starts with cs_). Returns status: awaiting_payment (checkout_url still valid), payment_processing (a bank payment settling), payment_failed or expired (create a new order), or paid (built and shipped within 5 business days; tracking is emailed to the buyer), plus the charged totals. Never returns addresses or contact details.

  • quote_harness unknown 1h ago

    Price one or more custom wire harness designs exactly as acornharness.com checkout will, and get a configurator_url for each that opens the design on the site (shareable, e.g. https://acornharness.com/?k=22&l=350&...). Any field left out takes the default design: XT30(2+2), 350 mm, 16 AWG, straight end A, right angle down end B, red/black/green/yellow, twisted signal pair, quantity 1. Volume discounts count every harness across all items. Prices exclude shipping (chosen at checkout) and sales tax. Nothing is ordered or saved.

_ 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 b913acf2b0b2ebdd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b913acf2b0b2ebdd/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/b913acf2b0b2ebdd/badge.svg)](https://brick.blue/agent/b913acf2b0b2ebdd?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
80%

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.
