Looking for an agent-native RequestBin alternative?

RequestBin was the original paste-a-URL webhook inspector, now absorbed into Pipedream's workflow platform. HookSense takes a different path — the agent-native callback layer where your AI agent creates an endpoint and awaits the result over MCP with wait_for_callback, signature-verified.

Why Choose HookSense

• Your agent awaits the result over MCP with wait_for_callback — no manual refresh, no polling
• MCP-native: npx @hooksense/mcp adds the callback toolset to Claude or Cursor
• Signature-verified callbacks so your agent only acts on trusted payloads
• Standalone callback layer — not buried inside a workflow platform
• replay_callback to re-fire a captured callback when a step needs another try
• Auto-retries and dead-letter coming soon (paid plans in early access)

Frequently asked

Is HookSense the modern RequestBin alternative?

It shares the paste-a-URL simplicity but targets a different user: RequestBin is a human inspector (now inside Pipedream), while HookSense is the agent-native callback layer where your agent calls create_callback_endpoint then wait_for_callback over MCP.

How does an agent get the result back vs RequestBin?

With RequestBin a human refreshes the page. With HookSense the agent calls wait_for_callback over MCP and blocks until the signed payload arrives or times out — no polling.

Does HookSense require signup like RequestBin?

No — install npx @hooksense/mcp and your agent can create a callback endpoint right away. Signup unlocks more endpoints, signature verification, and (soon) retries on paid plans, which are in early access.
