Overview

Hail is an MCP server that brings phone, SMS, and email capabilities to AI agents through a single remote endpoint. With OAuth login and zero local installation, Hail lets Claude, Cursor, VS Code, and other MCP clients place calls, send messages, and manage communications as native tools.

The server runs as a hosted service at https://mcp.hail.so, requiring only OAuth authentication to connect. Version v0.1.0 is published under the AGPL-3.0 license with source code available at hail-hq/hail on GitHub, where the project has reached 25 stars.

Hail belongs to the Communication category on mcp.site and works with any MCP-compatible client including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Hail for hail-hq, claim this listing to verify your ownership, earn the Verified badge, and keep your information current.
