Val

Overview

Val is a Model Context Protocol (MCP) server: QA agent for vibecoded apps. Real browser checks, your AI fixes them. Ship to green. In practice that means any MCP-compatible AI assistant can call Val's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package @nyx-intelligence/val-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need VAL_LICENSE_KEY. The current release is v0.10.1, with source at Wakizara/val-action on GitHub.

Val is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
