ℹ️ About MCP Plugin Builder

What this is: a builder that produces a Claude Code plugin (.zip) and a Codex (~/.codex/config.toml) snippet that expose only the tools you select as native MCP tools. Calls are proxied to the live API by onlinecybertools-mcp-server.

Why a subset: a 250-tool MCP firehose burns agent context and slows tool selection. Pick the 5–20 you actually need.

What runs on your machine: the generated plugin shells out to npx -y github:Jambozx/onlinecybertools-mcp-server, which runs a small Node 20+ MCP server over stdio. Requires Node installed.
