What is horizun marketplace?

A marketplace catalogue for open-source plugins from HorizunGroup. The supplied information lists a Microsoft Project plugin for auditing, rescheduling, and writing project schedules.

Use it to locate the Horizun Microsoft Project plugin.

It helps users find the listed plugin, but the description does not explain how the marketplace itself works.

horizun marketplace — Plugin for Claude Code by HorizunGroup

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Clone the repo

git clone --depth 1 https://github.com/HorizunGroup/horizun-msproject-mcp

Made for: Claude Code.

Security

Grade A, and why

horizun marketplace 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 21d 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.

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.
