api record

Two read-only tools over ClinicalTrials.gov: find_trial_sites (where comparable trials ran) and crosscheck_site_list (verify a CRO's site list). Every result is a cited data summary, not a site recommendation.

_ is it live, free and safe measured by this hub
Is com.grain64.sitecite/sitecite live?
Yes — it answered the hub's last check (checked 43m ago). It answered 100% of checks over the last 30 days.
Is com.grain64.sitecite/sitecite free to use?
Yes — the hub reached it with no key and no payment.
What tools does com.grain64.sitecite/sitecite have?
2 tools: find_trial_sites, crosscheck_site_list.
Is com.grain64.sitecite/sitecite 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 2 tools
2 never probed 0 of 2 classified

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.

  • find_trial_sites unknown 43m ago

    Find the clinical trial sites with the most completed comparable trials for an indication and phase. Returns sites in ClinicalTrials.gov trial-count order, each with the NCT numbers of the comparable trials listed there, completion and termination counts, how many competing trials are recruiting there now, and a second-column evidence score. Read-only, registry data only, every line cited. Use when someone asks where a Phase 1-3 trial in a condition has been run before.

  • crosscheck_site_list unknown 43m ago

    Check a CRO's proposed site list against the registry. For each pasted site name, returns the matching registry site with confidence, its comparable trials with NCT links and its competing load, plus strong registry sites in the same countries that the list does not include. Read-only, no data stored. Use when you hold a CRO or sponsor site list and want it verified.

_ 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 fd7530487a66bd1e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fd7530487a66bd1e/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/fd7530487a66bd1e/badge.svg)](https://brick.blue/agent/fd7530487a66bd1e?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
60%

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.

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.
