Is hookden live?

Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.

Is hookden free to use?

Yes — the hub reached it with no key and no payment.

What tools does hookden have?

7 tools: list_captures, get_capture, create_bin, send_test_webhook, set_response, verify_signature, wait_for_capture.

Is hookden safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

• list_captures reads unknown 2h ago

  List requests captured by a bin, oldest first. Compact summaries (id, method, path, time, content-type, body size, signature status). Use get_capture for full headers/body. Pass `after` (a capture id) to only see newer captures.

• get_capture reads unknown 2h ago

  Get one captured request in full: method, path, query, every header, and the body. Binary bodies are returned base64-encoded (up to 8KB, with a URL for the raw bytes).

• create_bin changes data unknown never probed

  Create a new webhook capture bin. Returns a public capture_url — point any webhook (Stripe, GitHub, Slack, your own service…) at it and every request sent there (any method, any subpath, headers + raw body) is stored. Then read what arrived with list_captures, get_capture, or wait_for_capture. Anonymous bins keep requests ~24h. No auth needed.

• send_test_webhook changes data unknown never probed

  Simulate a webhook delivery into a bin — no external sender or HTTP client needed. Seeds one realistic, clearly-labeled sample capture (default: a GitHub push event) and returns it in full, so you can exercise the whole loop (create_bin → send_test_webhook → list_captures / get_capture) entirely from MCP. Pass `example` to pick a provider payload from the /examples library (e.g. "stripe-payment-intent-succeeded", "slack-event-callback", "shopify-order-created"). Sample captures are marked as simulated and never count as real webhook traffic.

• set_response changes data unknown never probed

  Configure what a bin replies to webhook senders: HTTP status, content-type, body, custom response headers, optional delay. Body and header values support {{…}} templates rendered per-request from the INCOMING delivery — {{body.challenge}}, {{query.hub.challenge}}, {{header.x-hook-secret}}, {{hmac_sha256 body.plainToken YOUR_SECRET}} — so a bin can pass provider verification handshakes with zero code: Slack URL verification (body {{body.challenge}}), Zoom CRC (JSON with the hmac_sha256 helper), Meta/WhatsApp GET echo (text/plain {{query.hub.challenge}}), Strava (JSON {"hub.challenge":"{{query.hub.challenge}}"}), Asana (response header X-Hook-Secret: {{header.x-hook-secret}}). Only the fields you pass change; everything else keeps its current value. Works on bins created via create_bin by this same client; the incoming request is still captured in full either way.

• verify_signature reads unknown never probed

  Verify a webhook signature against a secret — 25 provider-exact schemes plus a generic HMAC mode, the same engine that computes ✓/✗ badges on captures. Covers HMAC-SHA256 (GitHub, Stripe, Svix/Standard Webhooks, Shopify-style base64, URL-signing Square/HubSpot/Trello…), ECDSA (SendGrid), RSA (Kick) and HMAC-MD5 (Patreon). Pass the scheme, the secret, the delivery's headers, and the BYTE-EXACT raw body (body_base64 for binary). The secret is used only for this one in-memory computation — never stored or logged. No bin needed. If verification fails, the #1 cause is a re-serialized body: point the real webhook at a capture bin (create_bin) to get the true raw bytes first.

• wait_for_capture reads unknown never probed

  Block until the next request arrives at a bin (or a timeout passes), then return it in full. Ideal flow: create_bin → configure the webhook sender → trigger it → wait_for_capture. If `after_id` is omitted, waits for the next capture after "now". Returns timed_out:true instead of erroring when nothing arrives.
