The reliable Rust layer for production AI agents
We build api0, the MCP gateway that turns your existing APIs into secure tools for Claude and other MCP-compatible clients.
api0: AI agents that act on your real systems
Connect Claude to your backend in under five minutes. api0 decides who is calling, which credential your backend receives and what the call costs, in one place.
“Book me a flight to Lisbon” → a real API call
- 1
Import your endpoints
Paste an OpenAPI spec or describe endpoints in plain English. Each one becomes an MCP tool.
- 2
Connect the client
Add api0 to Claude as a connector. Each user approves once through OAuth.
- 3
Govern execution
Every call is checked, sent with your backend’s credential, metered in credits and logged.
Rust and Swiss-made, by design
Agents that touch real systems need software that doesn’t break. Everything we ship is written in Rust and built in Switzerland, from the api0 gateway to our desktop tools.
- The api0 gateway and all its backends are written in Rust
- Desktop tools ship as single native binaries: no Electron, no telemetry unless you opt in
- Code-signed and notarized builds, verified on install
- Built and supported from Switzerland
Also built on the same stack
Native desktop tools for Azure Integration Services and Git, from the same Rust codebase.

C Gives You Control, But at What Cost?
C avoids garbage collection and gives manual memory control, but opens the door to dangerous bugs. Explore real-world memory issues and why they matter.
