Fixzi AI Validator

What is Fixzi MCP Server?

Fixzi monitors AI model JSON output for schema drift and API contracts for breaking changes. Connect Fixzi to Claude Code, Cursor, or any MCP-compatible AI tool to check your validators without leaving your editor.

Tools Available

• fixzi_list_validators — List all AI output validators in your Fixzi account
• fixzi_get_validator — Get details of a specific validator including its JSON schema, provider, and last check status
• fixzi_run_check — Run a synchronous validation check right now and get pass/fail with schema errors
• fixzi_list_checks — Get recent check history for a validator

Requirements

• A Fixzi account at https://fixzi.ai
• Pro+ plan (required for API access)
• An API token with validators:read ability — create one at https://fixzi.ai/settings/api-tokens
