Pipehero: An MCP Tunnel Built for Webhooks
carpediemAR · reddit · 2026-07-18
The author built a webhook tunnel called Pipehero to replace the tedious "ngrok + curl + manually pasting JSON into Claude/Cursor" debugging workflow.
Key features include:
- Exposes local services to the web like ngrok, but tailored for webhooks
- Real-time request inspection with under 100ms latency
- Replay requests after editing the body/method without triggering real server-side events
- Supports signature verification (like Stripe) to catch invalid or unsigned payloads early
- Monitors error rate spikes or silent drops
Crucially, it includes an MCP server, allowing agents like Claude or Cursor to directly read tunnel data, headers, and bodies, and even replay or generate synthetic webhooks without manual copy-pasting. The author notes the project is built entirely in Rust, has a usable free tier, and they are actively seeking feedback on the product and pricing.
