− > Webhook testing tools for developers. Capture, inspect, forward, and test webhooks with a dashboard, CLI, TypeScript SDK, and MCP server for AI agents.− Every endpoint on an account also receives email at its own address, so a signup flow that sends a webhook and a confirmation email can be checked in one place, and captured email can be forwarded to your server as signed JSON.− - Email forwarding: Forward every email an endpoint captures to your HTTPS URL as parsed JSON, signed with Standard Webhooks headers and retried for about a day− - Mock responses: Configure status codes, headers, and response bodies per endpoint, with conditional rules that route different responses based on method, path, headers, body content, JSON paths, or query params (first match wins)− - TypeScript SDK: `@webhooks-cc/sdk` for programmatic endpoint management, test assertions, and real-time streaming; `client.emails.waitFor()` and `extractCode()` for email tests, `client.forwarding` and `verifyForwardedEmail()` for email forwarding− - MCP server: `@webhooks-cc/mcp` connects AI coding agents (Claude Code, Cursor, VS Code, Codex, Windsurf)− - Provider detection: Built-in helpers for Stripe, GitHub, Shopify, Slack, Twilio, Paddle, and Linear webhooks− - Free: 50 requests per 24 hours, unlimited endpoints, 7-day retention, every feature including email capture and full CLI/SDK/MCP access− - Pro ($8/month): 100,000 requests per 30 days, 31-day retention− - Teams ($12/seat/month): a separate per-team subscription; each seat adds 100,000 requests per 30 days to a pooled team quota, and requests on endpoints shared with the team are kept 31 days− - Email forwarding: https://webhooks.cc/docs/forwarding− All API keys use the prefix `whcc_`. Keys are generated via the CLI with `whk auth login` or from the account page after signing in. See https://webhooks.cc/docs for setup instructions.− # Claude Code: plugin with the MCP server and the webhook testing skill− # The skill for Cursor, Codex, Copilot and other agents− npx skills add kroqdotdev/webhooks-cc− # Claude Code, MCP server only− # Cursor / VS Code / Windsurf− npx @webhooks-cc/mcp setup windsurf− Set the `WHK_API_KEY` environment variable to your API key.+ > Webhook and email testing tools for developers. Capture, inspect, forward, and test webhooks and email with a dashboard, CLI, SDKs for TypeScript, Python and Go, and an MCP server for AI agents.+ Every endpoint on an account also receives email at its own address, so a signup flow that sends a webhook and a confirmation email can be checked in one place, and captured email can be parsed with layouts and forwarded to your server as signed JSON, to Google Sheets or to a chat channel. mailhooks.cc is the mail-first front door to the same accounts, endpoints and plans.+ - Forwarding: up to 10 destinations per endpoint, each with its own kinds (HTTP, email or both), filter, format, throttle and delay: HTTP requests relayed as received, emails as parsed JSON signed with Standard Webhooks headers, your own JSON template with `{{ placeholders }}`, a Slack or Discord message, Google Sheets rows, a mail provider's inbound shape (Postmark, SendGrid, Mailgun, CloudMailin), or a file drop to SFTP, FTP/FTPS or S3 (Business); retried for about a day and logged+ - Layouts: read named fields and line items out of each email and parse CSV, TSV, Excel, OpenDocument and PDF text attachments before it is delivered; AI setup proposes the patterns from emails you pick, with your consent per request+ - Zapier and Make: apps that add a destination to an endpoint when a Zap or scenario turns on+ - Mock responses: Configure status codes, headers, and response bodies per endpoint, with conditional rules that route different responses based on method, path, headers, body content, JSON paths, or query params (first match wins), and `{{ placeholders }}` filled in from the request+ - TypeScript SDK: `@webhooks-cc/sdk` for programmatic endpoint management, test assertions, and real-time streaming; `client.emails.waitFor()` and `extractCode()` for email tests, `client.destinations` (and `client.forwarding` for the primary destination) and `verifyForwardedEmail()` for forwarding+ - Python and Go SDKs: `webhooks-cc` on PyPI and `webhooks.cc/go`, with the same waits, signed sends and signature checks, plus pytest fixtures and Go test helpers+ - MCP server: the remote server at https://webhooks.cc/mcp connects coding agents (Claude Code, Cursor, VS Code, Codex) and hosted agents (claude.ai, ChatGPT) with one OAuth approval in the browser; the local `@webhooks-cc/mcp` adds sends to localhost and a keyless sandbox+ - Agent sandbox: AI agents capture webhooks without an account (3 endpoints for 24 hours) and connect to a human's account once;
