Overview

## What YepCode does

YepCode turns developer-written code into tools an AI assistant can call. Inputs are described with JSON Schema, and the code runs inside an isolated sandbox with access to npm and PyPI packages plus environment variables held securely.

Processes are defined once and reused. They can be invoked on demand from a conversation or run on a schedule, and each execution is logged, so there is an audit record behind every call.

The app is aimed at developers who want AI tool execution they can program and observe rather than configure through a fixed interface. An example prompt in the record asks the assistant to locate the relevant workflow context inside YepCode.

### Who it is for

Engineering teams that want AI-callable functions backed by their own source code and package dependencies.

### What stands out

The tool definition is itself code the developer writes, with the input schema, runtime packages, and secrets under their control.

Availability

## Where YepCode is listed

YepCode is listed in the ChatGPT apps directory only. YepCode S.L. has no connector under the same domain in the Claude directory; 392 of the 3,150 products here are on both marketplaces, and this is not one of them.

ChatGPT apps are built on MCP, and the same server can back a Claude connector, so the absence is a distribution decision rather than a technical one.
