Bandmixr is an online mixing and mastering service for musicians. master_song opens the Bandmixr studio for a finished song: the song is checked in the browser and a 30-second mastered preview plays next to the original; the full master needs a Bandmixr account. check_mix opens the same studio focused on the report (loudness, true peak, clipping, stereo image, tonal balance). Songs dropped into the studio are analyzed in the browser, not uploaded, for the check. Mixing stems needs the person to connect their Bandmixr account: create_song (or open_song_studio for an existing song) opens the…

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.

  • check_mix open 49m ago

    Opens the Bandmixr Mix Analyzer in the chat. It checks a mix or master in the browser (the file is not uploaded): loudness (LUFS), true peak, clipping, stereo image and tonal balance, with a verdict for each and a 30-second mastered preview.

  • mix_and_master unknown never probed

    Mixes an existing song's stems and masters the mix in one go (draft, final mix, master), for example to mix it again with another genre or mastering style; a song made with create_song is already set up for this. It waits for the uploads, the analysis and the person's "Labels are correct" in the studio, then starts by itself. The mastering style is the one the person names (streaming when they name none). The studio shows the progress and plays the result; a new mix replaces the earlier version made in the chat (downloaded versions and mixes made on the website stay).

  • adjust_mix unknown never probed

    Changes a song mixed from stems the way the person asks after listening: a stem louder or quieter, muted or back in, more or less reverb, or placed left, center or right. One call takes all the changes for a song. Bandmixr then makes the mix and the master again with the changes (about as long as the first mix); the studio shows the progress and plays the new version, which replaces the earlier version made in the chat (downloaded versions and mixes made on the website stay). Stem ids, file names and the current settings come from get_song_status.

_ 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 c3337e7fe45e93ea.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c3337e7fe45e93ea/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/c3337e7fe45e93ea/badge.svg)](https://brick.blue/agent/c3337e7fe45e93ea?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.
