Gephyr turns your app's existing API into a secure connector for ChatGPT, Claude, Grok, Cursor and any agent that supports MCP. Your users sign in with the login they already have, then just ask, and their agent gets it done in your app. You choose what agents can do, risky actions ask the user first, and every call is logged. No code to write. Free to build and test; pay when you go live.
People are starting to ask their AI agent to do things instead of opening apps: "book my usual class", "move my 3pm", "what did I spend on food this month?". For most apps, the answer today is "I can't do that".
Gephyr fixes that without an engineering project. Point it at your API docs, choose what agents may do (read, write, or ask the user first), connect the login you already have, and publish. Your users get one link that works in ChatGPT, Claude, Grok, Cursor and any agent that supports MCP, and they sign in with their existing account.
A few things we cared about:
- Payments, cancellations and deletions can ask the user first, and every approved one gets a signed receipt anyone can check.
- Gephyr never runs anyone's code, and the AI app never sees your users' passwords.
- A dashboard shows which AI apps your users come from, what fails, and what people asked for that you don't offer yet.
- Free to build and test. You only pay when you go live.
I'd love to hear two things: what would you want an agent to do in your app, and what would stop you trusting it? I'll be here all day answering.
