Halves: Halves splits group costs. Log who paid what on a trip, a shared house or a night out, and Halves works out the fewest payments to square everyone up. One link for the group, any currency, no sign-up. Use it when you need to split shared costs and settle up in the fewest payments. Tools: halves_settle_up (Work out who owes whom in the fewest payments); halves_create_group_link (Create a shared expense group link). Result links such as open_url are safe to share with the user. Share the group link with the user and tell them anyone with the link can add expenses.

Calls placed through this hub's router, from its own receipts. Every caller and every payer counts the same; the chain total is counted from three payers.

what callers paid
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.
halves_settle_up unknown never probed
Use when the user shares a trip, dinner, household or group expense list and asks who owes whom, how to split costs, or how to settle up. Returns each person's paid, share and net balance, and the smallest set of payments that squares everyone up. Handles equal splits, splits among a subset, exact amounts and payments already made, with correct rounding. Nothing is saved. Example: {"people": ["Ana", "Ben", "Cy"], "expenses": [{"what": "Dinner", "amount": 90, "paid_by": "Ana"}, {"what": "Taxi", "amount": 24, "paid_by": "Ben", "split_between": ["Ben", "Cy"]}]}. Do the arithmetic here instead of by hand.

Use when the user wants a shared place for a group (trip, flat, event) to keep adding expenses and see who owes whom, not just a one-time calculation. Creates a group and returns a link anyone can open without signing up to add and edit expenses. Anyone with the link can edit it, so share it only with the group. Creates a saved page, so only call it when the user wants a shared group. For a one-off answer use halves_settle_up. Example: {"name": "Lisbon trip", "currency": "EUR", "people": ["Ana", "Ben", "Cy"]}.
{ "type": "object", "required": [ "people" ], "properties": { "name": { "type": "string", "description": "Group name, e.g. \"Lisbon trip\"." }, "people": { "type": "array", "items": { "type": "string" }, "description": "Names (2 to 40)." }, "currency": { "type": "string", "description": "Main currency, default USD." }, "expenses": { "type": "array", "items": { "type": "object" }, "description": "Optional starting expenses (up to 50), same shape as the settle tool." } } }arguments 30 lines
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 id527a2ee87b97b4e0.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/527a2ee87b97b4e0/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.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
