# ReceiveHQ

> Inbound email to webhook or blackhole storage, hosted in Germany. Drop-in Postmark, Mailgun/SendGrid, and CloudMailin payload formats. Agent-native MCP. €10/month or €100/year for 100k emails, then €10 per additional 100k. First 10 emails free. GDPR-aligned. Built by Cortena.

ReceiveHQ accepts SMTP on your domain, parses MIME, and either POSTs to your HTTPS webhooks or stores mail only (blackhole endpoints — status `blackholed`, no forward). Use it when EU data residency matters, when your agent reads mail via MCP/API, or when you want to keep an existing inbound webhook contract.

## Create an account

1. Open [https://receivehq.com/](https://receivehq.com/) and click **Sign in / Sign up**.
2. Enter your email — ReceiveHQ sends a magic link (no password).
3. Confirm the link, then open the console at [https://receivehq.com/inbox](https://receivehq.com/inbox).
4. Create a tenant, add an inbound domain (point MX to `mx.receivehq.com`), and add an endpoint:
   - **Blackhole** (`endpointKind: "blackhole"`) — receive and log mail, no webhook URL (ideal for MCP/agents; read via `list_messages`).
   - **Webhook** (`endpointKind: "webhook"`) — HTTPS POST in Postmark, Mailgun/SendGrid, or CloudMailin format.
5. After the free trial (10 emails / up to 3 trial tenants), subscribe via Stripe Checkout (€10/mo or €100/yr for 100k emails; €10 per additional 100k). Console and MCP for that tenant stay locked until you subscribe.

## Connect MCP (Cursor, Claude, and other OAuth MCP clients)

ReceiveHQ exposes a user-scoped Model Context Protocol server at `https://receivehq.com/api/mcp` (OAuth 2.1 + PKCE + Dynamic Client Registration).

Add this to your MCP client config (Cursor `mcp.json`, Claude Desktop, etc.):

```json
{
  "mcpServers": {
    "receivehq": {
      "url": "https://receivehq.com/api/mcp"
    }
  }
}
```

The client discovers OAuth via Protected Resource Metadata, registers if needed (DCR), opens a browser for login + consent, then stores tokens. Scopes: `mcp:read` (read tools), `mcp:admin` (mutations). Agents can configure inbound domains, add **blackhole** or **webhook** endpoints, and read mail without the console. Manage connected apps under Settings → MCP after signing in.
