YOUR MUSIC

Music in your library is used to fill episodes — tracks whose genre matches the show are picked automatically. Songs marked MUSICGEN are pulled live from the MusicGen app (published songs only); the panel below explains how that connection works.

MUSIC FROM MUSICGEN — HOW IT WORKS

This is a window, not a copy

Songs with the MUSICGEN badge live in the MusicGen app and are pulled in fresh each time this page loads. Nothing is stored here.

You're seeing published songs only

This list is exactly the songs you've published in MusicGen — the ones you're allowing radio to play. To edit, unpublish, or delete a song, do it in MusicGen; it updates here (and in future episodes) automatically. Cover art and play counts come from MusicGen too — art shows once the published version of a song has cover art.

How the two apps are connected

You link a MusicGen user ID to a show below. This service then calls the MusicGen API directly (server-to-server, authenticated with a MusicGen service key your admin configured) and pulls that user's published songs into the show's library.

Link or unlink MusicGen accounts per show here. Unlinking removes that user's songs from the show's library — it never touches the songs in MusicGen itself.

FOUR WAYS TO CREATE EPISODES

1. Manually — this page

Pick a show below, press Create Episode, and watch it build. Best for one-offs and trying things out.

2. Automatically, on a schedule

Shows with Automation turned on (edit a show to toggle it) get episodes built ahead of their scheduled air time — no clicks needed. Admins monitor this on the Automation page.

Manage shows →

3. From the command line

The grs CLI can script everything here: grs episodes create. It signs in with an API key from My Account.

4. By an AI agent (MCP)

A remote agent can connect to the Station MCP server and call tools like episodes_create to build and schedule episodes on its own.

STEP 4 OF 4

Create an Episode

API KEYS

API keys let tools sign in as you without Google sign-in — use them for the grs CLI, scripts, CI jobs, or AI agents. Each key starts with grs_ and is shown only once, right after you create it. Name keys after where they'll live (e.g. "laptop CLI", "github actions") so you know what breaks if you revoke one.

How to use a key

Send it in the X-API-Key header on any API call:

curl -H "X-API-Key: grs_your_key" \
  https://your-shows-host/api/v1/shows

Or set it once for the CLI:

export GRS_API_KEY=grs_your_key
grs shows list

Revoking a key disables it immediately — anything still using it gets a 401.

Episode Automation

Automation is a set of scheduled jobs (Google Cloud Scheduler) that call this service on a timer. The main one scans every station's schedule and builds upcoming episodes before they air; the others are upkeep. Each tile below is one automation — green runs on its own, yellow is paused, grey is off. Click a tile for full details.

Station MCP Server

Secure tool server for remote station agents. Exposes schedule, episode, gap-fill, weather, ad, and metadata tools via JSON-RPC. This server does not make autonomous decisions — a remote agent connects and decides what to do.

Server UUID

—

Stable tool-server identity for logs and alerts.

Last Tool Invocation

—

Last time a tool was called via the MCP endpoint or admin button.

Manually runs the gap-fill tool for testing. In production, a remote station agent connects to the MCP endpoint and calls tools as needed.
