com.webhook-studio/webhooks (MCP)

Webhook Studio provides keyless webhook endpoints that let an agent pipeline webhook traffic. It supports capturing provider events, waiting for them, replaying captured payloads into localhost, forwarding events to an app, and generating types from real traffic. The server offers a real endpoint, full headers, and raw body capture for debugging and integration work.

🛠️ Key Features

Keyless webhook endpoints
Capture live provider events with full headers + raw body
Wait for provider event delivery
Replay captured events into localhost
Forward events to an application
Generate types from actual captured payloads

🚀 Use Cases

Debugging webhook integrations with a zero-signup endpoint
Testing webhook flows by replaying real captured payloads
Building webhook integrations using types derived from real payloads

⚡ Developer Benefits

Types generated from actual captured payloads
Developer tooling for webhook testing and forwarding
Workflow centered on a single URL for event handling

⚠️ Limitations

Endpoint is described as “keyless,” with no additional supported authentication details provided here

Webhook Studio

A webhook pipeline your agent can drive — keyless. Provision a real endpoint, wait for the provider event, replay it into localhost, forward it to your app, and generate types from your actual captured payloads. Built for humans debugging webhooks and for AI agents building the integration.

Three jobs, one URL

Debug — a zero-signup endpoint, a live inbox with full headers + raw body, and signature verification results on every request.
Route — forward matching events to your backend with AND/OR conditions, and durable re-drive: a delivery interrupted by a crash or deploy is re-driven from a durable record, not silently dropped.
Learn — every event updates a durable model of what the provider actually sends your account. Ask for a TypeScript / Zod / JSON-Schema type and the optional fields are the ones genuinely sometimes absent in your traffic; ask what changed between two versions and get a breaking-change diff. No other webhook tool does this. Honest comparison: https://webhook-studio.com/compare

Use it from your AI tools (MCP)

Webhook Studio is a remote MCP server (Streamable HTTP, stateless). Add one URL:

bash

claude mcp add --transport http webhook-studio https://webhook-studio.com/mcp \
  --header "Authorization: Bearer $(curl -s -X POST https://webhook-studio.com/api/start | jq -r .api_token)"

That curl mints a keyless read + replay token (no signup) bound to a fresh 3-day endpoint. For full access — create endpoints, configure verification, stand up forwards — use a ws_live_… key from your dashboard.

Or add it to your client's MCP config (~/.cursor/mcp.json, .vscode/mcp.json, claude_desktop_config.json) — full setup for every client at https://webhook-studio.com/mcp/setup:

json

{
  "mcpServers": {
    "webhook-studio": {
      "url": "https://webhook-studio.com/mcp",
      "headers": { "Authorization": "Bearer ws_live_your_key_here" }
    }
  }
}

The Authorization header is optional — omit it for a public connection (the read/replay tools that accept a ws_anon_… token), or set a ws_live_… key for the full toolset.

Tools

Task-shaped, not resource-shaped — reach for them by intent:


`create_bucket` · `list_buckets` · `get_bucket` · `delete_bucket`	Provision and manage endpoints
`latest_event` · `list_events` · `get_event` · `wait_for_event`	Read events; block until one arrives
`replay_event` · `forward_bucket` · `list_deliveries`	Replay to localhost, forward, check results
`configure_verification`	Turn on HMAC with the provider's real secret
`list_schemas` · `get_schema` · `diff_schema` · `generate_types` · `find_correlation_keys`	The knowledge layer

Each tool maps 1:1 onto a /v1 REST route, so the REST reference is also the tool reference.

Keyless in one call (no MCP client needed)

bash

curl -X POST https://webhook-studio.com/api/start
# → { ingest_url, inbox_url, api_token: "ws_anon_…", expires_in_days: 3, ... }

Point a provider at ingest_url, hand the human inbox_url, and use api_token to read + replay over /v1 or /mcp. Full agent guide: https://webhook-studio.com/llms.txt
