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 yyh211/claude-meta-skill at ba6f50c572.

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

About this skill

What it does

The yyh211-mcp-builder skill generates Minecraft Command Portals (MCPs). MCPs are custom portals that can be configured to teleport players to specific locations or execute commands upon entry. This allows for complex automation and customized gameplay experiences within a Minecraft environment. The skill leverages Claude's reasoning capabilities to interpret user requests and translate them into functional MCP configurations.

When to use it

  • Automated Resource Delivery: Create an MCP that teleports players directly to a diamond ore vein when activated.
  • Custom Game Mechanics: Design an MCP that triggers a custom game event, like starting a mini-game or initiating a challenge, upon player entry.
  • Simplified Navigation: Build an MCP that instantly transports players between key locations within a large Minecraft world.
  • Complex Command Execution: Implement an MCP to run a sequence of commands when a player passes through it, automating tasks like item distribution or mob spawning.

Key capabilities

  • MCP Generation: Creates functional Minecraft Command Portal configurations.
  • Location Teleportation: Configures portals to teleport players to specified coordinates.
  • Command Execution: Enables the execution of custom commands upon portal entry.
  • Claude Integration: Leverages Claude's reasoning for accurate MCP generation.

Example prompts

  • "Create an MCP that teleports me to X:100, Y:64, Z:200."
  • "Build a portal that gives every player who enters a diamond block."
  • "Generate an MCP that opens the nether portal when someone walks through it."

Tips & gotchas

  • Ensure you have appropriate permissions within your Minecraft world to place and configure command blocks. The skill generates the configuration, but requires proper setup in-game.
