# Webhook Studio

> Lets your agent spin up webhook endpoints, wait for real events, replay them to localhost and generate types from your actual traffic.

Webhook Studio sits between webhook providers such as Stripe, GitHub and Twilio and your app. It captures every event with its headers, raw body and signature result, forwards and replays events, and learns the shape of what each provider actually sends your account. Its hosted MCP server gives your agent that whole pipeline, so it can build and test a webhook integration end to end.

What you can do with it
- Create webhook endpoints and get the URL to point a provider at, plus a live inbox link for you
- Wait for the next matching event, so "send a test webhook" becomes one step in the chat
- Read the latest event, or search past events by time, provider, type or signature result
- Replay a captured event to localhost or any URL, with the original signature intact or re-signed with your own secret
- Forward matching events to your backend with AND/OR conditions, and see which deliveries failed and why
- Turn on HMAC signature verification with the provider's own signing secret
- Generate TypeScript, Zod or JSON Schema types, or a full Next.js or Express handler, from the payloads your account received, and diff schema versions for breaking changes

How it connects
Add https://webhook-studio.com/mcp as a hosted server with an Authorization: Bearer header. Webhook Studio offers two kinds of token:
- A keyless ws_anon_ token from POST https://webhook-studio.com/api/start, with no signup. It can read and replay events on one fresh endpoint and expires with it after 3 days.
- A ws_live_ API key from the API page of a free account, for everything: creating endpoints, verification, forwards and schemas.
Webhook Studio documents setup for Claude Code, Cursor, VS Code and other MCP clients.

Good to know
The server connects without a header, but its tools then answer that an API key is missing, so add a token before you use it. A keyless token that calls a tool outside its scope, such as creating an endpoint, gets a 401; Webhook Studio enforces that on its server, so a keyless token is safe to hand an agent.

## Install

You'll need:

- `Authorization` (optional): Bearer <token>. A keyless read+replay token from POST /api/start (ws_anon_...), or a full-access API key from your dashboard (ws_live_...). See https://webhook-studio.com/mcp/setup

Replace each `<NAME>` placeholder with your own value.

### ChatGPT

In ChatGPT on the web: Plugins → + → Add custom MCP server, then paste https://webhook-studio.com/mcp under Connection. Business and Enterprise plans; Pro can add read-only servers.

### Claude

In Claude (web or desktop): Customize → Connectors → Add custom connector, then paste https://webhook-studio.com/mcp

### Muse

In Muse: In a Muse chat, ask it to create a custom connector for the MCP server at https://webhook-studio.com/mcp. Then tap Connect on the card it shows and sign in, or add your key.

### Grok Bot

In Grok Bot: In a chat with your Bot, say "Add this MCP server: https://webhook-studio.com/mcp". It confirms the details with you and sets it up, and the tools are ready from your next message.

### Gemini

In Gemini: At gemini.google.com: Settings → Connected Apps → Add a custom app, then paste https://webhook-studio.com/mcp

### Grok

In Grok on the web: At grok.com/connectors: New Connector → Custom, then enter https://webhook-studio.com/mcp and sign in if it asks.

### GitHub Copilot

Add to VS Code: vscode:mcp/install?%7B%22name%22%3A%22webhook-studio%22%2C%22type%22%3A%22http%22%2C%22url%22%3A%22https%3A%2F%2Fwebhook-studio.com%2Fmcp%22%7D

Copilot CLI:

```shell
copilot mcp add --transport http webhook-studio https://webhook-studio.com/mcp
```

Add to .cursor/mcp.json:

```json
{
  "mcpServers": {
    "webhook-studio": {
      "url": "https://webhook-studio.com/mcp"
    }
  }
}
```

### Claude Code

Run in your terminal:

```shell
claude mcp add --transport http webhook-studio https://webhook-studio.com/mcp
```

### Codex

Run in your terminal:

```shell
codex mcp add webhook-studio --url https://webhook-studio.com/mcp
```

### Antigravity

Add to ~/.gemini/config/mcp_config.json:

```json
{
  "mcpServers": {
    "webhook-studio": {
      "url": "https://webhook-studio.com/mcp"
    }
  }
}
```

### Gemini CLI

Run in your terminal:

```shell
gemini mcp add --transport http webhook-studio https://webhook-studio.com/mcp
```

### Replit

In Replit: At replit.com/integrations, open MCP Servers → + Add MCP server, paste https://webhook-studio.com/mcp (add any headers under Advanced settings), then click Test & save.

### OpenClaw

Run in your terminal:

```shell
openclaw mcp add webhook-studio --url https://webhook-studio.com/mcp --transport streamable-http
```

If it needs a key or sign-in: For https://webhook-studio.com/mcp, add --header NAME=value for each header it needs, or --auth oauth and then run openclaw mcp login webhook-studio.

### OpenCode

Run in your terminal:

```shell
opencode mcp add webhook-studio --url https://webhook-studio.com/mcp
```

If it needs a key: For https://webhook-studio.com/mcp, add --header 'NAME=value' for each header it needs. Add --global to use it in every project.
