About Mayorana
We build the reliable Rust layer for production AI agents.
Who we are
Mayorana is a Swiss software company. We build api0, an MCP gateway that lets AI agents act on real systems instead of only talking about them.
Most teams that try agents hit the same wall: the model is ready, but connecting it to internal APIs means glue code, keys pasted into prompts, and a backend that can’t tell which person an agent is acting for. api0 handles that in one place.
We also ship native desktop tools for Azure Integration Services and Git, built on the same Rust stack.

api0: secure MCP tools from the APIs you already have
api0 turns your existing REST APIs into tools for Claude and other MCP-compatible clients. Connect Claude to your backend in under five minutes.
- Import an OpenAPI spec, or describe endpoints in plain English
- Each user approves once through OAuth, and every call carries who it is for
- Credits, access control and a log of every call, decided at one gateway
“Book me a flight to Lisbon” → a real API call
How we work
Products, not promises
Everything we talk about is something you can try today: api0 in the browser, the desktop tools as a download.
Rust end to end
Agents that touch real systems need software that doesn’t break. The gateway, its backends and our desktop apps are all written in Rust.
Security in the layer, not the prompt
Who may call what is enforced by the gateway. Backend credentials stay in api0, and the model never sees them.
Source you can read
Our desktop tools are source-available on GitHub: free for personal, educational and non-profit use, licensed for commercial use.
