## Description
Send, validate, debug webhooks for AI agents

## Tools
Capabilities this server exposes over MCP:

- **Stripe** — `t=TIMESTAMP,v1=SIGNATURE` format with timestamp tolerance
- **GitHub** — `sha256=SIGNATURE` or `sha1=SIGNATURE` format
- **Slack** — `v0=SIGNATURE` with `v0:timestamp:body` signing scheme

## Claude Desktop Quick Installation
Remote MCP endpoint (confidence: high). Install path detected from listing signals. Add as a URL/SSE server in your client:

```json
"mcpServers": {
  "webhook": {
    "url": "https://modelcontextprotocol.io/"
  }
}
```

## Documentation & README


# mcp-webhook-tools

Webhook management and testing tools for AI agents, built on the [Model Context Protocol](https://modelcontextprotocol.io/).

## 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=SIGNATURE` format with timestamp tolerance
- **GitHub** — `sha256=SIGNATURE` or `sha1=SIGNATURE` format
- **Slack** — `v0=SIGNATURE` with `v0:timestamp:body` signing 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`                           |

Each payload includes randomized IDs, current timestamps, and suggested headers. Use the `overrides` parameter to customize specific fields.

### webhook_debug

Analyze a webhook request end-to-end:

- Parse and categorize headers (content-type, signature, timestamp, delivery ID, custom)
- Validate the request body (size, JSON validity, encoding)
- Auto-detect the provider (Stripe, GitHub, Slack)
- Verify the signature if a secret is provided
- Check timestamp freshness (default 300s threshold)
- Report all issues found

### webhook_retry_schedule

Calculate a retry schedule with exponential backoff. Shows each attempt's delay, cumulative elapsed time, and scheduled ISO timestamp. Configurable base delay, max delay cap, multiplier, and jitter.

## Setup

```bash
npm install
npm run build
```

## MCP Configuration

Add to your MCP client config:

```json
{
  "mcpServers": {
    "webhook-tools": {
      "command": "node",
      "args": ["path/to/mcp-webhook-tools/dist/index.js"]
    }
  }
}
```
