Agent-first YouTube Shorts uploader for the YouTube Data API. It is designed for Codex, Claude, Cursor, Hermes, OpenClaw and any MCP client that needs a predictable upload workflow with dry-run safety, OAuth readiness checks and structured output.
Use it when an agent needs to prepare, validate or upload Shorts through the official API without touching YouTube Studio UI.

Or run directly:
npm exec --yes --package=youtube-shorts-agent -- youtube-shorts-agent doctor
youtube-shorts-agent manifest --client codex
youtube-shorts-agent doctor
youtube-shorts-agent privacy-audit
youtube-shorts-agent auth-url --redirect-uri http://localhost:8787/callback
youtube-shorts-agent upload-short --video ./short.mp4 --title "Launch title" --caption-file copy.txt
youtube-shorts-agent list-recent --max-results 10
Dry-run is enabled by default. Set YOUTUBE_DRY_RUN=false only when doctor reports a complete OAuth setup and you intend to call the live API.
This is the full first-run path. Every step here is dry-run safe β no credentials are required and nothing is sent to YouTube. The output below is captured verbatim from a real run.
1. Check readiness. With no OAuth configured, doctor confirms you are in dry-run mode:
youtube-shorts-agent doctor
{
"ok": true,
"dry_run": true,
"configured": {
"client_credentials": "missing",
"access_token": "missing",
"refresh_token": "missing"
},
"missing_count": 3,
"ready_for_live_upload": false,
"next_steps": [
"Current mode is dry-run. Validate metadata and agent flow before live uploads."
]
}
2. Prepare a Short and its caption.
printf 'Launching the agent-first Shorts uploader.\n#shorts #ai #agents' > copy.txt
# short.mp4 is your vertical 9:16 clip
3. Run the upload in dry-run. No network call is made; the tool returns the exact job and result it would publish, so an agent can validate metadata before going live:
youtube-shorts-agent upload-short \
--video ./short.mp4 \
--title "Agent-first Shorts upload" \
--caption-file copy.txt \
--tags ai,agents \
--duration 24
{
"ok": true,
"dry_run": true,
"job": {
"id": "youtube_1780082215631",
"platform": "youtube",
"status": "queued",
"createdAt": "2026-05-29T19:16:55.631Z",
"caption": "Launching the agent-first Shorts uploader.\n#shorts #ai #agents",
"targetUrl": "",
"mediaPaths": ["./short.mp4"],
"metadata": {
"title": "Agent-first Shorts upload",
"youtube_title": "Agent-first Shorts upload",
"youtube_tags": ["ai", "agents"],
"youtube_contains_synthetic_media": true,
"video_duration_sec": 24,
"video_aspect_ratio": "9:16"
}
},
"result": {
"provider": "youtube_official",
"platformPostId": "dryrun_1780082215631",
"releaseUrl": "https://www.youtube.com",
"raw": { "dryRun": true, "jobId": "youtube_1780082215631" }
}
}
platformPostId is prefixed with dryrun_ and releaseUrl is the YouTube root β both signal that nothing was uploaded. The id, createdAt and dryrun_* values vary per run.
4. Confirm the channel listing path (returns an empty list in dry-run):
youtube-shorts-agent list-recent --max-results 5
{ "items": [] }
Going live. Configure OAuth (youtube-shorts-agent auth-url --redirect-uri http://localhost:8787/callback, then exchange the callback code for tokens), set YOUTUBE_CLIENT_ID / YOUTUBE_CLIENT_SECRET / YOUTUBE_ACCESS_TOKEN / YOUTUBE_REFRESH_TOKEN in .env, re-run doctor until ready_for_live_upload is true, then set YOUTUBE_DRY_RUN=false and re-run the same upload-short command.
youtube-shorts-mcp
Default is stdio. Optional Streamable HTTP β no session id, JSON responses, loopback only:
npx -y -p youtube-shorts-agent youtube-shorts-mcp --http
# GET http://127.0.0.1:3032/health
# POST http://127.0.0.1:3032/mcp (sessionless)
Env: YOUTUBE_MCP_HOST, YOUTUBE_MCP_PORT, YOUTUBE_MCP_TRANSPORT=http.
Hermes-style config:

args: ["-y", "youtube-shorts-agent"]

Recommended first calls:
youtube_connection_statusyoutube_privacy_audityoutube_upload_short| Tool | Purpose |
|---|---|
youtube_agent_manifest | Install/runtime guidance for Codex, Claude, Cursor, Hermes and OpenClaw |
youtube_connection_status | OAuth and dry-run readiness without token values |
youtube_privacy_audit | Upload scope, synthetic media and local file boundaries |
youtube_oauth_authorize_url | PKCE authorization URL with local session storage |
youtube_upload_short | Dry-run or live Shorts upload |
youtube_list_recent_videos | Lightweight channel verification |
Use youtube-shorts-agent. First call youtube_connection_status and youtube_privacy_audit.
If uploading AI-generated media, keep containsSyntheticMedia=true. Never print token values.
Copy .env.example to .env. Keep .env and .agent-data/ out of Git.
The upload tool sets containsSyntheticMedia=true by default for AI-generated or AI-edited videos. Override only when that is not true for the asset.
