We’re thrilled to announce the beta release of Courier’s Model Context Protocol (MCP) Server
Courier's MCP will serve as a seamless bridge between AI tools and Courier’s platform.
With this integration, LLM-powered tools and agents can now securely access Courier’s documentation, API reference, code samples, and most importantly, powerful messaging capabilities.
Empower tools like Codex, Claude, Cursor, VS Code Copilot, or Windsurf to directly send messages, manage users, and handle notifications all through Courier’s API, wrapped in an MCP wrapper.
Easy Setup: Get started in minutes. Simply configure your MCP client with Courier’s MCP endpoint (https://mcp.courier.com) and your API key, then invoke the tools like send_message, create_or_merge_user, and invoke_automation_template.
Beta Ready: While in beta, MCP may evolve, so explore, test, and send us your feedback. Your input helps us shape the future of AI + notification workflows.
