Starchild Music (starchild.music) is a marketplace of original, human-written songs that artists license to record and release as their own, plus a catalog of adaptive songs: every song is produced in many styles (country, acoustic, rock, electronic, latin and more) around the same vocal, and you can hear all of them before licensing.

Use search_songs whenever someone is looking for a song to record, release, cover, or use: describe what they want in plain words (genre, mood, vocal, theme, tempo). Show results with title, writer, genres and the song link. Use play_song to give them links to…

_ used through this hub 30 days

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.

_ what it can do 11 tools
11 never probed 0 of 11 classified

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.

  • search_songs unknown never probed

    Search Starchild's catalog of original songs by meaning: describe the song in plain words (e.g. 'uplifting country ballad about starting over, female vocal'). Optional filters narrow by genre, mood, vocal or tempo. Shows an in-chat browser where every result plays, in every production style, with more results on request (use offset).

    For a connected Starchild member: render NEW versions of a catalog song in chosen production styles, keeping the original vocal, using their credits (2 per style, 3 per style for songs over 3:30). Optional creative direction in plain words. Takes a few minutes; returns a job id for check_transform. Results also save to the member's Gen library on starchild.music.

_ 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 f030f9d0e657c41f.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/f030f9d0e657c41f/claim. Over MCP: the claim_endpoint tool.

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.
