Overview

What is Fixzi AI Validator?

Fixzi AI Validator monitors AI model JSON output for schema drift and API contracts for breaking changes. It connects to Claude Code, Cursor, or any MCP-compatible AI tool to check validators directly from the editor.

How to use Fixzi AI Validator?

Add the server to your MCP client config (e.g., ~/.claude/claude_desktop_config.json) using the streamable-http transport URL https://fixzi.ai/api/mcp and a Bearer API token with validators:read ability. For Cursor, add it as a remote server in Settings → MCP. Once connected, ask your AI assistant to list validators, run a check, or view check history.
