Registry code: 89e746ab5f74ed0e
Free website and app checks from Red Center Studio. No API key. geo_audit checks AI search readiness, ai_crawler_check shows whether AI search crawlers can reach a site, domain_health checks domain and certificate expiry, DNS and email security, spof_scan finds single points of failure in a domain's providers, decode_error explains Bubble error messages.

- Is rcs-tools live?
- Yes — it answered the hub's last check (checked 15m ago). It answered 100% of checks over the last 30 days.
- Is rcs-tools free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does rcs-tools have?
- 5 tools: spof_scan, ai_crawler_check, geo_audit, decode_error, domain_health.
- Is rcs-tools 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.

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
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
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.
spof_scan unknown never probed
Find which companies a business depends on for email, sign-in, DNS, website hosting, outbound email and SaaS, using public DNS only, and what a single outage would stop. Returns the layers, the vendors, a risk score and recommendations. Free, no key. Rate limited per connection and to about 20 fresh scans an hour; repeat scans of the same domain within an hour come from cache.

Check whether the main AI search crawlers from OpenAI, Anthropic, Perplexity and Google can reach a website: the robots.txt rule for each one, and a firewall test that requests the home page with each crawler's user agent and compares the answer with a normal visit. Returns each crawler with pass or fail and copy-paste fixes. Reads robots.txt and the home page only. Free, no key. Rate limited per connection.

Check how ready a public website is for AI assistants and search engines: AI crawler access in robots.txt, sitemap, llms.txt, structured data, titles and page basics. Returns a score out of 100, each check with pass, warn or fail, and copy-paste fixes. Reads the home page, robots.txt, sitemap.xml and llms.txt only. Free, no key. Rate limited per connection.

Explain an error message from an app built on Bubble: the likely cause, and a link to the full fix guide. Matches the text against the same list as the decoder page at redcenterstudio.com/decoder/. Free, no key.
{ "type": "object", "required": [ "error" ], "properties": { "error": { "type": "string", "description": "The error message, or the key words from it." } }, "additionalProperties": false }arguments 13 linesdomain_health unknown 15m ago
Check the things that quietly take a business offline: when the domain expires (RDAP), when the latest certificate issued for the site expires and who issued it (public Certificate Transparency logs), whether the site answers over HTTPS, DNS basics, and email security (SPF, DMARC and DKIM at common selectors). Returns each finding with pass, warn or fail and a plain fix. Public data only. Free, no key. Rate limited per connection.

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 id89e746ab5f74ed0e.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/89e746ab5f74ed0e/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.
