xither
Registry code: f055b63f030703e6
Xither keeps dated, hashed copies of the pages AI and SaaS vendors publish: sub-processor lists, data processing agreements, trust pages and deprecation schedules. Every fact these tools return is a stored reading with its source URL and the date Xither read it; cite both when you repeat it. Xither reports what a page says, not what it means. Use search_vendors when unsure of a vendor's slug, then lookup_vendor for one vendor.

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.
notice_windows reads open 23h ago
Every sub-processor notice window Xither can quote: the number of days (business days where the clause says so) each vendor's own terms state for a new sub-processor, and what that number counts (basis: 'objection' = time to object once told, 'notice' = notice before the change, 'unstated' = the clause does not settle it), with the verbatim clause, its source URL and the date Xither read it. The same table as www.xither.com/notice-windows. A vendor not listed has no window Xither could quote.
{ "type": "object", "properties": {}, "additionalProperties": false }arguments 5 linesupcoming_model_retirements reads open 23h ago
Model and API retirement dates from the retirement tables vendors publish, as Xither last read them, soonest first: model, date, the replacement the vendor names, the verbatim table row, source URL and read date. Optional vendor filter; within_days defaults to 90, maximum 365; at most 50 rows. Covers only vendors whose retirement tables Xither reads.
{ "type": "object", "properties": { "vendor": { "type": "string", "maxLength": 200, "minLength": 1, "description": "Optional vendor name, slug or domain." }, "within_days": { "type": "integer", "default": 90, "maximum": 365, "minimum": 1, "description": "How many days ahead to look, from today." } }, "additionalProperties": false }arguments 19 linessearch_vendors reads unknown 6h ago
Find vendors in the Xither record by name, slug or domain. Returns up to 10 matches, each with its name, slug and record URL, and no record data. Pass a slug to lookup_vendor for the record.
{ "type": "object", "required": [ "query" ], "properties": { "query": { "type": "string", "maxLength": 100, "minLength": 2, "description": "Part of a vendor name, a slug or a domain." } }, "additionalProperties": false }arguments 15 lineslookup_vendor reads unknown 23h ago
The Xither record for one vendor. Use it when the user names a specific vendor and asks where it publishes its sub-processor list or DPA, how long its terms give to object to a new sub-processor, what it has changed, or when its models retire. Returns: where it publishes its sub-processor list and data processing agreement and when Xither last read each page (or why a page cannot be read); the notice window its agreement states for new sub-processors (quoted, with source URL and read date); its public changes to either document with permalinks; and model retirement dates it publishes for the next 365 days. One vendor per call; accepts a name, slug or domain. If the name matches several vendors it returns their slugs to call again with; if it matches none, the vendor is not in the record, which says nothing about what the vendor publishes. Use search_vendors instead when you only have part of a name, notice_windows to compare windows across vendors, and upcoming_model_retirements for retirements across vendors. Changes appear 30 days after Xither records them; subscribers get them the same morning at www.xither.com/pricing.

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 idf055b63f030703e6.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/f055b63f030703e6/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.
