inboxy — Claude Code MCP server: what it does, how to install
Remote MCP server giving agents access to @inboxy.net aliases, incoming mail, and RSS feeds while keeping your personal mailbox private.
claude mcp add --transport http inboxy https://mcp.inboxy.netWhat inboxy does
This is a hosted service reachable at https://mcp.inboxy.net via Streamable HTTP. The server exposes 48 tools divided into eight functional sets. Assistants can search incoming messages, review RSS feeds, manage disposable aliases, and send replies without touching your primary mailbox.
Interactive clients authenticate via OAuth 2.1 with PKCE, while unattended background runs rely on static bearer keys starting with ik_. A static key can be locked to a single alias, which restricts outbound headers and protects the rest of the account. Outbound actions have hard boundaries: replies are capped at 5 per hour, and all outgoing messages carry a mandatory service attribution line.
Custom sender addresses are rejected server-side, so outgoing mail is permanently bound to an @inboxy.net address.
What it helps with
- Let assistants read incoming messages without exposing a personal inbox
- Generate disposable
@inboxy.netaliases on demand - Read and track updates across RSS feeds
- Send rate-limited replies with enforced sender identity
Example prompts for the agent
- Check my @inboxy.net inbox and summarize unread messages.
- Generate a fresh email alias for signing up.
- List unread articles from my RSS feeds.
