Tern

Overview

Tern is a Model Context Protocol server that connects your AI assistant to the Tern E2E testing platform. It exposes Tern's testing capabilities as tools that Claude, Cursor, and other AI clients can invoke directly, letting you automate end-to-end tests through natural conversation.

The server runs locally on your machine via the npm package @zyf8827/tern-mcp, which communicates with MCP over stdio. Install it with npx -y @zyf8827/tern-mcp. You'll need an API Key to authenticate. The latest release is v0.3.0.

Tern appears in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and others. If you maintain Tern, claim this listing to verify ownership, earn a Verified badge, and keep information up to date.
