nyxid

nyxid is a plugin for Claude Code from ChronoAIProject/NyxID. Its manifest loads nothing; the 1 skill, 1 MCP server it bundles cost 39 tokens per session together, scanned A, original, Apache-2.0.

A credential broker that lets an agent connect to services and call their APIs without showing the agent the API keys or OAuth tokens. OAuth is a common sign-in method that grants an application limited access to another service.

In plain words
What is it for?
Use it to connect third-party services through NyxID and make authenticated API calls without directly exposing the credentials.
Why use it?
It keeps sensitive connection credentials out of the agent's visible context while still allowing approved service connections.

Security

Grade A, and why

nyxid 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 8d 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.

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 — 39 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
