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.

Generate a full audio track from a text prompt using Boost Audio AI. Returns a mix and optionally separated stems openable in the Boost Audio DAW. Use this when the user wants AI-generated music, an instrumental, a song with lyrics or a quick demo from an idea.

boost_audio_studio_builder unknown never probed

Open Soundra-style studio wizard inside this conversation. Asks the user 4 short questions (purpose, genre, budget, room size) and builds 3 studio proposals (budget / optimal / premium) with hardware per slot (microphone, audio interface, monitors, headphones, MIDI controller, DAW) and direct purchase links to supersound.pl with UTM tracking. Use when the user asks to recommend studio gear, plan a home studio for X PLN/EUR, swap a device, or compare price tiers. IMPORTANT: ALWAYS pass `locale` (pl/en/de) inferred from the user's chat language so prices are localized (PL=PLN, EN/DE=EUR) and product names + supersound.pl URLs are returned in the right language.

_ 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/6b86e30c59d5e0e6/badge.svg)](https://brick.blue/agent/6b86e30c59d5e0e6)

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

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.
