View on GitHub ↗

Overview Installation

Overview

Willitsend is an MCP server that performs deterministic pre-send linting for SMS and iMessage messages. It detects silent carrier filtering issues and segment blowups before messages are sent, helping you avoid deliverability problems and unexpected message fragmentation.

The server runs locally on your machine via the npm package willitsend, which communicates with MCP clients over stdio. Install it with npx -y willitsend. It requires an API Key for authentication. The current release is v0.1.0, distributed under the MIT license, with source code available at abryfs/willitsend on GitHub.

Willitsend appears in the Communication category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim your listing to verify ownership and keep information up to date.
