What This Skill Does

HookCatch is a CLI tool for creating webhook bins and exposing localhost ports via public tunnels. It captures and inspects incoming HTTP requests, making it practical for testing third-party webhook integrations without deploying code.

It combines webhook inspection and localhost tunneling in a single CLI with JSON output designed for script automation, avoiding the need to juggle separate tools for each task.

When to use it

  • Capture Stripe payment webhook payloads during local development
  • Expose a local API server to GitHub for push/PR event testing
  • Inspect raw request bodies from Twilio SMS callbacks
  • Replay a previously captured webhook to a different endpoint
  • Filter and audit webhook traffic by HTTP method or timestamp

Example Workflow

Here's how your AI assistant might use this skill in practice.

INPUT

User asks: capture and inspect incoming Stripe webhooks locally

AGENT
  1. 1Run `hookcatch bin create --name "Stripe Test" --format json` to get a public webhook URL
  2. 2Configure the returned URL as the webhook endpoint in the Stripe dashboard
  3. 3Trigger a Stripe event (e.g., a test payment)
  4. 4Run `hookcatch bin requests <binId> --format json` to fetch captured payloads
  5. 5Parse the JSON output to extract event type and relevant fields
OUTPUT

A list of captured Stripe webhook requests with full headers, body, and metadata available for inspection or further processing
