Common questions
Is Fixzi — MCP & API Schema Drift Monitor safe?
It passed 2 of 2 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 4 months ago, and the latest version (1.0.2) reached the registry 4 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Puter MCP, Agent-Native Slides, Agent-Native Forms

Fixzi MCP Server
Monitor MCP servers, API contracts, and AI output schemas — from inside Claude Code, Cursor, or any MCP client.
Your MCP servers, APIs, and AI outputs can break while still returning 200. Fixzi watches the contracts your integrations depend on, classifies every change (breaking / warning / info), and alerts you before your users hit it. This MCP server lets your AI tools query and operate those monitors directly.
