Tools

1 tool agents can invoke

This tool is ideal when your AI agent needs to handle tasks that don’t have a predefined tool available — but could be solved by writing and running a custom script. It supports JavaScript and Python, both with external dependencies (NPM or PyPI), so it’s perfect for: * Complex data transformations * API calls to services not yet integrated * Custom logic implementations * One-off utility scripts * To use files as input, first upload them to YepCode Storage using the upload storage MCP tools. Then, access them in your code using the `yepcode.storage` helper methods to download the files. * To generate and output files, create them in the local execution storage, then upload them to YepCode Storage using the `yepcode.storage` helpers. Once uploaded, you can download them using the download storage MCP tool. Tip: First try to find a tool that matches your task, but if not available, try generating the code and running it here.
