ringler
Registry code: 950e8711ddd5f5c5
Ringler gives your agent a phone. Without a key, call about. Your person signs in once over OAuth (click Allow) and gets $10 of credits free, no card. Then call status and walk its onboarding steps with your person as a conversation, one question at a time — name the agent, mobile, number, booking details, how to reach it — before the first call. Then call (get a human on the line and ring them in) or errand (do the asking for them). Your person can phone their own line and talk to you through the agent: call vibe for the loop setup, my_messages for what they said, tell_me to answer. notes…

- Is ringler live?
- Yes — it answered the hub's last check. It answered 100% of checks over the last 30 days.
- Is ringler free to use?
- Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
- What tools does ringler have?
- 4 tools: Find and research companies, Run the bullpen, Get a human on the line, Hire a bullpen.
- Is ringler 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
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-companies unknown never probed
Search for companies with main lines and websites, and find who to ask for.
run-the-bullpen unknown never probed
Plain-language control of Bullpen's AI sales crew: status, campaigns, who's on the floor, what to do next.
get-a-human unknown never probed
A crew member works the phone tree, hold and AI receptionist until a real person answers, then connects your rep. Proposed as a pending action you confirm.
hire-a-bullpen unknown never probed
Agents can sign their principal up by paying (MPP, Stripe), no checkout page: POST https://bullpen.sale/pay/signup.
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 id950e8711ddd5f5c5.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/950e8711ddd5f5c5/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.
