What is Hostinger Mail MCP server?
The Hostinger Mail MCP server is the agent-facing side of Agentic Mail, the API layer Hostinger added to its business email in late May 2026. It runs at https://mcp.mail.hostinger.com/mcp and gives an AI client the mailbox itself: list and search messages, read them, send and reply, flag, move and delete, and manage folders and webhooks.
There are two ways in. Claude's connector directory has had an official Hostinger Mail connector since 4 August 2026, and Hostinger Agent, the company's own assistant, gained the same connection with OAuth on 8 October 2026; both sign in through the browser, with no token to copy. Other MCP clients, including Claude Code, Cursor, Windsurf and JetBrains IDEs, are set up from hPanel's Agentic Mail page with a Mail API token that can be limited to selected mailboxes and to mail actions, webhook management or both.
The same mailbox is reachable through a REST API, SDKs for Node.js, PHP, Python and Go, a CLI and webhooks. Agentic Mail is included on every Hostinger business email plan. It is separate from the Hostinger Connector, which manages hosting and domains.
How to install Hostinger Mail MCP server
https://mcp.mail.hostinger.com/mcpIs Hostinger Mail MCP server worth it?
The server's appeal is price and plumbing rather than novelty. A Hostinger mailbox with full API, MCP and webhook access starts at $0.39 a month on a 48-month term, against $20 a month for AgentMail's Developer plan, and the browser sign-in from Claude or Hostinger Agent removes the token handling that most mail MCP servers need. The trade-offs are that the price is an upfront multi-year commitment renewing at $1.59 to $3.99 a month, and that the address is a normal Hostinger mailbox rather than an inbox designed for agents.
The tool surface is broad and generic. The Claude directory lists six tools that wrap the Mail API (operation listing, documentation and read, write and delete calls) rather than one tool per action, so what the agent can do is whatever the API allows. In Claude, sending happens directly from the chat; Hostinger describes no confirmation step in the connector itself, and its own guidance is to start with drafts.
The main guardrail lives in the mailbox, not the protocol. Each mailbox has outgoing allow and block lists of addresses or domains; when the allow list is non-empty, mail to anyone else is rejected, and the block list wins on a conflict. Hostinger recommends the allow list for autonomous agents. Token scoping to selected mailboxes limits the damage of a leaked token, but a token's permissions are coarse: mail actions, webhooks, or both.
Usage data from Hostinger gives a sense of scale. Across 14 weeks to 18 October 2026 it counted about 213 million agent actions, of which 2.5% were sends, from 25,000 weekly active users and 39,000 mailboxes; the company says it analysed only action types, not message content.
Gaps: no published rate limits, no tool-level permission filter on the hosted endpoint, no retention or AI-training terms specific to Agentic Mail on the product pages, a single webhook event (message.received) whose payload is truncated, and no open-source code.
Where it earns its place

Let Claude triage the shared support inbox and draft replies
Connect the Hostinger Mail connector from Claude's directory with a browser sign-in, have Claude search and summarise new mail and save drafts, and set the allow list to client domains before enabling sends. A Standard mailbox at $0.99 a month on the 48-month term covers 3,000 emails a day.

Give the agent its own address that reacts to incoming mail
Create a token scoped to one mailbox, point a webhook at a public HTTPS endpoint for message.received, and fetch the full message through the API, since the webhook payload is truncated. Starter at $0.39 a month allows 1,000 sends a day.
