HookSense vs Hookdeck: Agent callback layer vs event gateway

Hookdeck is a webhook infrastructure platform for routing and retrying events between apps. HookSense is the agent-native callback layer: your AI agent creates a callback endpoint and awaits the result over MCP with wait_for_callback, signature-verified. Different layers for different jobs.

Why Choose HookSense

  • Your agent awaits the result over MCP with wait_for_callback — no queue to provision, no consumer to poll
  • MCP-native: npx @hooksense/mcp adds the callback toolset to Claude or Cursor in one command
  • Built for AI agents awaiting a single signed result, not for DevOps wiring app-to-app event routing
  • Signature verification built-in on every inbound callback (Hookdeck makes you wire this yourself)
  • Hook at $29/mo (early access) for the agent-callback use case, far below Hookdeck Growth at $499/mo
  • Auto-retries and dead-letter coming soon (paid plans in early access)

Frequently asked

What's the difference between HookSense and Hookdeck?
HookSense is the agent-native callback layer — an AI agent creates an endpoint and awaits a signed result over MCP with wait_for_callback. Hookdeck is infrastructure for routing, retrying, and transforming webhooks between applications. Different layers for different jobs.
Is HookSense cheaper than Hookdeck?
For the agent-callback use case, yes — there's a free tier with callback endpoints and MCP, then Hook at $29/mo and Sense at $99/mo (early access). You're not paying for an app-to-app event gateway you don't need. Hookdeck Team is $39/mo and Growth is $499/mo.
Does HookSense replace Hookdeck?
For app-to-app event routing, transformations, and fan-out retries across many consumers — no, Hookdeck fits that. For an AI agent that needs to create a callback endpoint and await a single signed result over MCP — yes, that's exactly what HookSense is built for.
