New — webhooks your AI agents can wait on. Hook & Sense opening to early access.

Alternative to · Beeceptor

Beeceptor mocks APIs for humans. HookSense gives agents callbacks.

Beeceptor is a capable API mocking and inspection tool — for a developer at the keyboard. An AI agent doesn't mock APIs; it needs to create a callback endpoint and await a result. HookSense is built for that: create_callback_endpoint, then wait_for_callback over MCP, signature-verified — no polling, no mocking layer in the way.

What developers tell us about Beeceptor

  • It's a mocking and inspection tool for humans — no way for an agent to await a result over MCP.
  • Webhook inspection is one feature bolted onto an API-mocking product, not a callback primitive.
  • No signature verification on inbound callbacks, so an agent can't trust the payload.
  • No wait_for_callback primitive — polling is the only way to learn a result arrived.

Why teams switch

Your agent awaits the result over MCP

create_callback_endpoint then wait_for_callback — the agent blocks until the signed payload arrives. No mocking layer, no polling.

MCP-native, agent-first

`npx @hooksense/mcp` adds create, wait, verify, and replay tools to Claude or Cursor. Built for agents, not for a person clicking around.

Signature-verified callbacks

verify_signature is built in — the agent only acts on a payload it can trust. Beeceptor offers no signature verification.

Auto-retries and dead-letter (soon)

Failed callbacks retry with backoff and land in a dead-letter queue so an agent never silently loses a result. Paid plans are in early access.

Pricing, side by side

Beeceptor

$25/mo (Team)

Free: 50 req/day, 10-day retention; bundles API mocking

HookSense

$0 / $29/mo (Hook)

Catch: callback endpoints + MCP. Hook: more endpoints, signature verification, retries (soon)

How to migrate (15 minutes)

  1. 1Install the MCP server: `npx @hooksense/mcp` in Claude or Cursor.
  2. 2Have your agent call create_callback_endpoint for a signed callback URL.
  3. 3Hand it to the long-running tool, async job, or human approver.
  4. 4If you used Beeceptor for API mocking too, keep it for that — use HookSense for agent callbacks.
  5. 5The agent calls wait_for_callback and acts on the verified payload.

FAQ

Is HookSense a Beeceptor alternative?

For the agent-callback use case, yes. Beeceptor bundles API mocking with a human-facing inspector; HookSense is the agent-native callback layer where your agent creates an endpoint and awaits a signed result over MCP.

Does HookSense do API mocking like Beeceptor?

No — that's not its job. HookSense focuses on agent callbacks: create the endpoint, await the result, verify the signature. If you need a full mock API, keep Beeceptor for that workflow.

How does an agent get the callback result?

It calls wait_for_callback over MCP, which blocks until the signed payload arrives or times out — no polling, no manual checks.

Give your agent a callback URL.

Add HookSense to Claude or Cursor with `npx @hooksense/mcp`. Free to start; request early access for paid plans.
