> Callable Studio
Make your API work in every AI agent.
I build, test and maintain MCP servers for API companies, so ChatGPT, Claude and Cursor can use your product correctly, not just call it.
Independent developer based in India. Everything is delivered on your own Cloudflare account, and you own the code.
The foundation for an agent-ready API
01
Curated
Your API may have hundreds of endpoints. Agents choose better from 12 to 20 well-described tools than from all of them at once.
02
Safe
Every tool is labelled read-only, write, or destructive, with notes on cost and side effects. A GET request that deletes data gets flagged, not hidden.
03
Tested
A set of 30 test prompts, 10 of them held back, measures whether an agent picks the right tool and arguments, before and after tuning.

How a pilot works
- You send your OpenAPI spec and a sandbox test key. I never need your production keys.
- I read the spec and propose the tool list, showing which tools are read-only and which are not.
- I build the server, run the test prompts, and share the results with you, good or bad.
- I hand over the code and a setup guide. You decide whether to go further.
What I don’t promise
I can’t promise that agents will use your server, that traffic or revenue will grow, or that a directory such as ChatGPT’s or Claude’s will approve a listing. I don’t claim any server is fully secure or immune to prompt injection.
What I do promise is a tested, documented server and the evidence behind it. A free generator may be all you need. If so, I’ll tell you.
