metaplex-agent

metaplex-agent is a plugin for Claude Code from nirholas/metaplex-agent-mcp. Its manifest loads nothing; the 1 skill, 1 MCP server it bundles cost 63 tokens per session together, scanned A, original, Apache-2.0.

A plugin that connects a coding agent to the Metaplex Agent Registry on Solana. It uses an MCP server to mint and register AI-agent identities on the blockchain.

In plain words
What is it for?
Use it when an AI agent needs a Metaplex asset and an EIP-8004 identity on Solana.
Why use it?
It provides a ready-made connection for deploying an agent to the registry instead of setting up the server integration yourself.

Security

Grade A, and why

metaplex-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Contents

What it installs

The manifest is a name and a version. 1 skill, 1 MCP server travel with it, and installing the plugin installs all of them — 63 tokens a session between them. Each is measured on its own page, and each can be installed alone.

Files

What ships with it

1 file beside plugin.json in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
