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.

Start monitoring a new asset (website/domain) in YOUR Merlonix account. Provide a hostname and asset_type; optionally a label and which checks to enable. Returns the created asset. Requires an API key with write scope. Subject to your plan asset quota (a full or non-paying plan returns an error).

arguments 26 lines

check_email_blacklist reads unknown never probed
Check whether a domain or IP is listed on the major DNS blocklists (DNSBLs) that mail providers consult before accepting mail — the usual reason legitimate mail silently lands in spam. Returns each zone checked, whether it is listed, and the return code. Deterministic DNS lookups, no LLM.

mcp-tool
{ "type": "object", "required": [ "domain" ], "properties": { "domain": { "type": "string", "description": "A public domain or IP address, e.g. example.com or 203.0.113.10" } }, "additionalProperties": false }

acknowledge_alert changes data unknown never probed

Acknowledge one of YOUR alerts by its alert id (from list_my_alerts) — marks it as seen/being-handled without resolving it. Optionally attach a note. Requires an API key with write scope.

mcp-tool

{
  "type": "object",
  "required": [
    "alert_id"

    }
  },
  "additionalProperties": false

arguments 17 lines

delete_asset changes data unknown never probed
STOP monitoring one of YOUR assets and remove it, by its asset id (from list_my_assets). This is irreversible — its check history goes too. Requires an API key with write scope.

mcp-tool
{ "type": "object", "required": [ "asset_id" ], "properties": { "asset_id": { "type": "string", "description": "The asset id from list_my_assets (a UUID)." } }, "additionalProperties": false }
arguments 13 lines
check_broken_links reads unknown 15h ago
Scan one web page for dead links (4xx/5xx/unreachable) and mixed content (http subresources on an https page). Returns each link with its status. Single-page scan, not a crawl — pass the exact page URL. Rate-limited to a few scans per minute, so batch calls will be throttled.

mcp-tool
{ "type": "object", "required": [ "url" ], "properties": { "url": { "type": "string", "description": "The exact page URL to scan, e.g. https://example.com/pricing" } }, "additionalProperties": false }
arguments 13 lines
check_mcp_health reads unknown 3h ago
Health-check a live MCP (Model Context Protocol) server by URL: performs a real JSON-RPC initialize handshake, then tools/list, and returns whether it is up/degraded/down, its protocol version, server name/version, the callable tool/resource/prompt inventory, transport, and handshake latency. Deterministic — no LLM. Use it to verify your own MCP server is alive and spec-compliant.

mcp-tool
{ "type": "object", "required": [ "url" ], "properties": { "url": { "type": "string", "description": "The MCP endpoint URL, e.g. https://example.com/mcp" } }, "additionalProperties": false }
arguments 13 lines
get_vendor_status reads unknown 3h ago
Get the current status plus 30-day status history of one monitored vendor by slug (e.g. "cloudflare"). Use list_vendor_status to discover valid slugs.

mcp-tool
{ "type": "object", "required": [ "slug" ], "properties": { "slug": { "type": "string", "description": "Vendor slug, e.g. cloudflare" } }, "additionalProperties": false }
arguments 13 lines
check_domain_health reads unknown 3h ago
Check the live SSL/TLS certificate (validity + expiry + issuer), DNS records (A/AAAA/MX/NS resolution), and domain-registration (RDAP) expiry of any public hostname. Each leg fails soft and is reported independently.

mcp-tool
{ "type": "object", "required": [ "hostname" ], "properties": { "hostname": { "type": "string", "description": "A public hostname, e.g. example.com" } }, "additionalProperties": false }
arguments 13 lines
check_agent_readiness reads unknown 26h ago
Score how ready a website is for AI agents and answer engines. Fetches /llms.txt, /robots.txt, and the homepage and returns a letter grade with per-signal findings. No browser rendering or LLM call — deterministic HTTP/parse.

mcp-tool
{ "type": "object", "required": [ "hostname" ], "properties": { "hostname": { "type": "string", "description": "A public hostname, e.g. example.com" } }, "additionalProperties": false }

_ 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.

Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /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-endpoint with this listing's id 2930fef0d37158a6.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/2930fef0d37158a6/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/2930fef0d37158a6/badge.svg)](https://brick.blue/agent/2930fef0d37158a6?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

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.
