Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned mcp-use/skills at 3bf0eaa4b0.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

The mcp-use-chatgpt-app-builder skill enables AI agents to interact with ChatGPT's application building tools, allowing them to create and manage custom GPTs directly. It streamlines the workflow of defining personas, instructions, and knowledge bases for new applications without manual interface navigation.

When to use it

  • Automate the creation of specialized assistants for specific domains like coding or customer support.
  • Rapidly prototype new GPT concepts by iterating on prompts and knowledge sources instantly.
  • Deploy custom AI applications that require unique system instructions or restricted context windows.
  • Manage multiple GPT configurations within a single agent workflow to handle diverse tasks.

Key capabilities

  • Direct integration with ChatGPT's app builder API for programmatic creation.
  • Dynamic configuration of application names, descriptions, and distinct personas.
  • Management of knowledge base uploads and retrieval settings for the generated apps.
  • Execution of build commands to finalize and publish new AI applications.

Example prompts

  • "Create a new GPT named 'CodeReviewer' that specializes in Python best practices with a strict tone."
  • "Build a customer support assistant using my uploaded FAQ PDF as the primary knowledge base."
  • "Configure a new app called 'TravelPlanner' to act as an expert travel agent focusing on budget-friendly itineraries."

Tips & gotchas

Ensure you have valid API credentials configured for ChatGPT before attempting to build applications, as the skill relies on external authentication. Be mindful of token limits when defining complex instructions or uploading large knowledge bases during the initial build process.
