Model Context Protocol for AI agents

@senderz/mcp on npm — the only Model Context Protocol server in the messaging market. Any MCP-aware agent can send iMessage and SMS, list conversations, manage templates, and check delivery via typed tool schemas. See /integrations/claude-code for the Claude Code-specific setup guide.

Install

One command. Any MCP agent.

The same command works in Claude Code. Adapt the host invocation for Cursor, Windsurf, or any custom agent.

Add senderZ to Claude Code

claude mcp add senderz -- npx @senderz/mcp --api-key sz_live_xxx

FAQ

Frequently asked questions

MCP vs REST API — when should I use which?

Use MCP when an AI agent (Claude Code, Cursor, or a custom agent) needs to send messages as part of an agentic workflow. Use the REST API when your application code calls senderZ directly. MCP wraps the REST API — the underlying endpoints are identical.

Which AI agents support MCP?

Claude Code, Cursor, Windsurf, and any agent built on the Model Context Protocol specification. The list grows as more tools adopt MCP. @senderz/mcp works with all of them.

Is MCP the same as function calling?

Related but different. Function calling lets an LLM invoke functions you define in a prompt. MCP is a standardized protocol for tools that any compatible agent can discover and use without per-prompt configuration. @senderz/mcp exposes senderZ tools via MCP so agents discover them automatically.
