Engineering Lead

We had three engineers maintaining MCP servers. Now we just update the OpenAPI spec and Automiel handles the rest.

Finally, a tool that understands the API is the source of truth, not the prompt.

Frequently asked questions

What format does my API spec need to be in? +
Automiel works with OpenAPI 3.0 and 3.1 specs. Provide a file path or URL, and we handle the rest. Swagger 2.0 specs are automatically converted.
Which LLMs are supported? +
Automiel generates standard tool definitions that work with Claude, GPT-4, Gemini, Llama, and any model that supports function calling. The output format can be customized per provider.
Do I need to change my existing API? +
No. Automiel reads your spec and generates the LLM integration layer. Your API stays exactly as it is. If your spec is accurate, the tools will work.
How does authentication work? +
Automiel supports OAuth out of the box, as well as webhook forwarding. Each request includes headers with identifiers for the user and the LLM making the call, so you always know who triggered what.
Can I customize the generated tools? +
Yes. Override descriptions, add examples, exclude endpoints, or modify parameter handling. The generated code is yours to extend.
