feedhook-mcp

MCP server for Feedhook — turn a YouTube channel into a webhook: your endpoint gets a signed HTTP POST ~8 seconds after a new video is published. No polling, no YouTube API quota. Feedhook does YouTube's WebSub plumbing (hub subscription, verification handshake, ~5-day lease renewals, retries with backoff) and resells it as a clean API; this package is the agent front door.

Use it

claude mcp add feedhook -e FEEDHOOK_API_KEY=fh_your_key -- npx -y feedhook-mcp

Or in any MCP client config:

{
  "mcpServers": {
    "feedhook": {
      "command": "npx",
      "args": ["-y", "feedhook-mcp"],
      "env": { "FEEDHOOK_API_KEY": "fh_your_key" }
    }
  }
}

No key yet? Add the server without the env var and ask your agent to call create_account (free plan: 1 feed) — the key is returned once; save it as FEEDHOOK_API_KEY.

Tools

| Tool | Does | |---|---| | create_account | Free signup → API key (returned once) | | get_account | Plan, feed limit, feeds in use | | create_subscription | channel id + callback URL → webhook on every new video | | list_subscriptions | All subscriptions with state + delivery counts | | get_subscription | One subscription incl. recent delivery log (per-attempt HTTP results) | | test_subscription | Send a signed test.ping through the real pipeline to verify your receiver | | upgrade_plan | Free → Pro ($9/mo, 10 feeds): returns a Stripe Checkout URL to open in a browser | | delete_subscription | Unsubscribe + stop deliveries |

The webhook your endpoint receives

POST <your callbackUrl>
x-feedhook-event: video.published
x-feedhook-delivery: <uuid>
x-feedhook-signature: sha256=<hex HMAC-SHA256 of the raw body, keyed with your subscription secret>

{
  "event": "video.published",
  "subscriptionId": "…",
  "videoId": "dQw4w9WgXcQ",
  "channelId": "UC…",
  "title": "…",
  "author": "…",
  "publishedAt": "2026-06-11T15:54:18+00:00",
  "url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ",
  "receivedAt": "…"
}

Non-2xx responses are retried 5 times with backoff. Respond within 15 seconds.
