api record

Hookden gives you disposable public HTTPS endpoints that capture every request sent to them. Typical flow: create_bin → give the capture_url to a webhook sender (Stripe, GitHub, a cron, your own code) → wait_for_capture (blocks up to 45s) or list_captures → get_capture for full headers/body. To try the loop with no external sender, send_test_webhook seeds a realistic labeled sample into a bin. set_response configures what a bin replies (status/content-type/body/headers/delay; {{…}} templates rendered from the incoming request let a bin pass Slack/Zoom/Meta/Strava verification handshakes with…

_ used through this hub 30 days

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • get_capture unknown never probed

    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).

    mcp-tool

    {
  "type": "object",
  "required": [
    "bin",
    "id"
  ],
  "properties": {
    "id": {
      "type": "integer",
      "description": "capture id from list_captures / wait_for_capture"
    },
    "bin": {
      "type": "string",
      "description": "bin id or slug"
    }
  },
  "additionalProperties": false
}
    arguments 18 lines
  • wait_for_capture 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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "bin"
  ],
  "properties": {
    "bin": {
      "type": "string",
      "description": "bin id or slug"
    },
    "after_id": {
      "type": "integer",
      "description": "return the first capture with id greater than this; default = latest id at call time"
    },
    "timeout_seconds": {
      "type": "integer",
      "description": "1-45 seconds to wait (default 20)"
    }
  },
  "additionalProperties": false
}
    arguments 21 lines
  • create_bin 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.

    mcp-tool

    {
  "type": "object",
  "properties": {},
  "additionalProperties": false
}
    arguments 5 lines
  • list_captures unknown never probed

    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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "bin"
  ],
  "properties": {
    "bin": {
      "type": "string",
      "description": "bin id (or custom slug) from create_bin"
    },
    "after": {
      "type": "integer",
      "description": "only captures with id greater than this (default 0)"
    },
    "limit": {
      "type": "integer",
      "description": "max results, 1-50 (default 20)"
    }
  },
  "additionalProperties": false
}
    arguments 21 lines
  • send_test_webhook 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.

    mcp-tool

    {
  "type": "object",
  "required": [
    "bin"
  ],
  "properties": {
    "bin": {
      "type": "string",
      "description": "bin id (or custom slug) from create_bin"
    },
    "example": {
      "type": "string",
      "description": "optional example payload slug from /examples (default: a GitHub push event)"
    }
  },
  "additionalProperties": false
}
    arguments 17 lines
  • set_response 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 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.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
100%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
