demo-stage — MCP server by mrieck/demoday-claude-plugin

demo-stage

demo-stage is an MCP server for Claude Code from mrieck/demoday-claude-plugin. Its token cost is not measured, scanned A, original, MIT.

A configured MCP server named demo-stage, started with Node.js. MCP is a way for an AI coding agent to connect to external tools.

In plain words

What is it for?: It is intended to expose the capabilities implemented in its server program, but those jobs cannot be identified from the description.
Why use it?: The supplied information does not say what external actions or data this server provides.

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable. Also seen: listed in a Claude config.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Security

Grade A, and why

demo-stage 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 2mo ago.

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.

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.
