Create a free Feedhook account (1 feed). Returns the API key ONCE — surface it to the user and have them save it as FEEDHOOK_API_KEY in this server's environment; it cannot be retrieved again. Skip this tool if FEEDHOOK_API_KEY is already set.

Show the current account: email, plan, feed limit, and how many feeds are in use. Requires FEEDHOOK_API_KEY.

Turn a YouTube channel into a webhook: Feedhook will POST signed JSON {event:'video.published', videoId, title, author, url, publishedAt, …} to callbackUrl ~8s after every new video. The response includes a per-subscription secret (shown once) for verifying the X-Feedhook-Signature header (sha256 HMAC of the raw body).

List the account's channel→webhook subscriptions with state (pending/active/unsubscribed), lease expiry, and delivery counts.

Get one subscription including its recent delivery log — each delivery shows the videoId, status (delivered/retrying/failed), and per-attempt HTTP results. Use this to check whether webhooks are arriving.

Send a signed test.ping through the real delivery pipeline to a subscription's callback URL — verify the receiver works without waiting for a real video. Check get_subscription afterwards for the delivery result.

Upgrade the account from free (1 feed) to Pro ($9/mo, 10 feeds). Returns a Stripe Checkout URL — give it to the user to open in a browser and pay; the plan flips automatically after checkout. Call this when create_subscription returns a 402 feed-limit error.

Delete a subscription — unsubscribes from YouTube's hub and stops all deliveries.
