Metaplex Skill
Last updated March 4, 2026
Metaplex Skill is an Agent Skill — a knowledge base that gives AI coding agents accurate, up-to-date knowledge of Metaplex programs, CLI commands, and SDK patterns.
Summary
The Metaplex Skill gives AI coding agents accurate knowledge of all Metaplex programs, CLI commands, and SDK patterns.
- Covers five programs: Core, Token Metadata, Bubblegum, Candy Machine, and Genesis
- Supports CLI, Umi SDK, and Kit SDK approaches
- Works with Claude Code, Cursor, Copilot, Windsurf, and other compatible agents
- Uses progressive disclosure to minimize token usage while providing full coverage
Instead of relying on hallucinated APIs or incorrect flags, your AI agent can reference the Skill to get accurate commands and code on the first try.
Installation
Install the Skill in Claude Code, Cursor, Copilot, or any agent that supports the Agent Skills format.
How It Works
Learn how progressive disclosure keeps context lightweight while providing full coverage.
Programs Covered
The Skill covers five Metaplex programs and their full operation sets:
| Program | Purpose | CLI | Umi SDK | Kit SDK |
|---|---|---|---|---|
| Core | Next-gen NFTs with plugins and royalty enforcement | Yes | Yes | — |
| Token Metadata | Fungible tokens, NFTs, pNFTs, editions | Yes | Yes | Yes |
| Bubblegum | Compressed NFTs via Merkle trees | Yes | Yes | — |
| Core Candy Machine | NFT drops with configurable guards | Yes | Yes | — |
| Genesis | Token launches with fair distribution | Yes | Yes | — |
Operations Supported
The Skill provides reference material for three approaches to Metaplex development:
- CLI (
mplx) — Direct execution of Metaplex operations from the terminal. Asset creation, uploads, Candy Machine deployment, tree creation, transfers, and more. - Umi SDK — Full programmatic access covering all programs. Fetches by owner/collection/creator, DAS API queries, delegate management, and plugin configuration.
- Kit SDK — Token Metadata operations using
@solana/kitwith minimal dependencies.
Compatible Agents
The Skill works with any AI coding agent that supports the Agent Skills format:
