The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

list_resources open 3h ago

Browse the StealthStack ARD index — agentic resources (agents, MCP servers, skills, catalogs) discovered across the open web. Optionally filter by kind, domain, or trust. Returns a count, a kind breakdown, and the page of resources, each with its connect URL when the publisher provides one; otherwise the inline connection or pull details. Use search_resources for a specific need.

search_resources unknown never probed

Search the StealthStack ARD index for agentic resources (agents, MCP servers, skills, catalogs) discovered across the open web. Free-text query over name/description/tags, ranked by the index's relevance score (best match first). Optionally filter by kind, domain, or trust. Each result includes the connect URL when the publisher provides one; otherwise the inline connection or pull details.

get_resource unknown never probed
Get the full record for one discovered ARD resource by its identifier (URN), as returned by search_resources / list_resources. Includes the connect URL when the publisher provides one; otherwise the inline connection or pull details. Also returns type, publisher, version, trust, source, description, tags, and example queries.

_ 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.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/49472ba395fc93df/badge.svg)](https://brick.blue/agent/49472ba395fc93df)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ how we know

card completeness

70%

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.
