_ is it live, free and safe measured by this hub
Is countrycalling-codes live?
Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
Is countrycalling-codes free to use?
Yes — the hub reached it with no key and no payment.
What tools does countrycalling-codes have?
11 tools: normalize_phone_numbers, diagnose_dialing_problem, get_dialing_instructions, format_international_phone_number, analyze_phone_number, compare_phone_numbers, get_phone_input_rules, find_calling_windows, ….
Is countrycalling-codes 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.

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.

  • lookup_country_calling_code reads open 11h ago

    Look up international country calling codes by free text, ISO code, dial code, or region. Optionally return reviewed, source-linked dialing examples. This tool does not verify live subscriber numbers.

  • get_dialing_instructions reads unknown 18h ago

    Prepare origin-specific dialing guidance for reviewed countries. Provide origin and destination separately; no phone number returns safe placeholder patterns. Network-dependent results remain conditional.

  • format_international_phone_number reads unknown 2h ago

    Normalize a phone number into a plausible international format using reviewed country-specific rules. Processing is ephemeral. This tool does not query carriers, HLR/HSS, MNP databases, or live subscribers.

  • analyze_phone_number reads unknown 2h ago

    Analyze a number using versioned numbering metadata. National numbers need numberCountryCode; exit prefixes need originCountryCode. Reports uncertainty and rule evidence, never live subscriber status.

  • compare_phone_numbers reads unknown 18h ago

    Compare two numbers after analysis. Missing context produces indeterminate. Extensions must match unless extensionPolicy is explicitly ignore; equality does not establish ownership.

_ 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 6d1ed5a9526f81de.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/6d1ed5a9526f81de/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/6d1ed5a9526f81de/badge.svg)](https://brick.blue/agent/6d1ed5a9526f81de?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
100%

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.
