Webhook
Handles the full webhook lifecycle for AI agents: sending POST requests with retries and exponential backoff, validating HMAC signatures for Stripe, GitHub, and Slack using timing-safe comparison, and generating realistic test payloads for common events like payment_intent.succeeded or push notifications. The debug tool parses headers, detects providers, checks signature validity and timestamp freshness in one pass. Useful when your agent needs to trigger webhooks to external services, verify incoming webhook authenticity, or simulate webhook scenarios during development without hitting live endpoints.

mcp-webhook-tools
Webhook management and testing tools for AI agents, built on the Model Context Protocol.
Tools
webhook_send
Send a webhook payload to any URL with custom headers, body, and content-type. Supports automatic retry with exponential backoff and jitter. Returns detailed attempt records including status codes, timing, and errors.
webhook_validate
Validate webhook signatures using HMAC-SHA256 or HMAC-SHA1. Includes built-in patterns for:
- Stripe —
t=TIMESTAMP,v1=SIGNATUREformat with timestamp tolerance - GitHub —
sha256=SIGNATUREorsha1=SIGNATUREformat - Slack —
v0=SIGNATUREwithv0:timestamp:bodysigning scheme
Uses timing-safe comparison to prevent timing attacks.
webhook_generate_payload
Generate realistic webhook payloads for testing. Supported events:
| Service | Events |
|---|---|
| Stripe | payment_intent.succeeded |
| GitHub | push, pull_request |
| Slack | message |
