The Durability Curve is a publication by Harry Floyd about which kinds of work keep their value as AI gets cheaper. This server gives read-only access to its public archive: essays, the claim ledger behind each checked essay, and the dated calls printed in The Durability Curve Weekly.
Start with search. Read a result in full with get_essay, get_claim_ledger or get_weekly_calls. When you quote or summarise, cite the canonical page URL given in each result (durabilitycurve.com/blog/..., /claims/..., /calls/). The markdown copy is there to be read; the page is what to link.

last good check
of 4 tools
The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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_weekly_calls unknown never probed
Get the calls printed in The Durability Curve Weekly: dated, checkable predictions, each with the confidence printed at the time and the date or event it resolves on. The wording is exactly as printed and never changes after publication. outcome is null until a call resolves. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

Search the public archive of The Durability Curve: essays on which kinds of work keep their value as AI gets cheaper, the checked claims in each essay's claim ledger, and the dated calls printed in The Durability Curve Weekly. Returns ranked matches, each with its kind (essay, claim or call), a snippet and the canonical URL. Read a match in full with get_essay, get_claim_ledger or get_weekly_calls. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

Default 5." }, "query": { "type": "string", "maxLength": 200, "minLength": 1, "description": "What to look for, in plain words, e.g. \"agent reliability\" or \"memory chip deposits\"." } } }arguments 22 linesget_essay unknown never probed
Get the full public text of one Durability Curve essay as markdown. Its frontmatter carries the title, date, series and canonical URL, and a link to the essay's claim ledger when it has one. For a paid essay only the free part is public, and the text says where it stops. When citing, link the canonical URL in the frontmatter. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

Lowercase letters, digits and hyphens. Get it from search." } } }arguments 14 linesget_claim_ledger unknown never probed
Get the claim ledger for one essay: each load-bearing claim it makes, the source it was checked against, the quoted words, where in the source they appear, the date the source was read, and a status saying how the claim was checked. The response defines every status. Claims removed during checking are listed separately under "struck", with the reason; they are not claims the essay makes. Only some essays have a ledger: search results and get_essay link to one when it exists. These tools retrieve The Durability Curve's public material. They do not certify that any claim is true.

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 id8aee69e2be2a4f95.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/8aee69e2be2a4f95/claim.
Over MCP: the claim_endpoint tool.

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.
