nyxid

nyxid is a plugin for Claude Code, Cursor from ChronoAIProject/NyxID. Its manifest loads nothing; the 1 skill, 1 command it bundles cost 62 tokens per session together, scanned A, original, Apache-2.0.

A plugin that connects Cursor agents to NyxID, a service for obtaining credentials, finding services, and forwarding API calls without revealing upstream secrets.

In plain words
What is it for?
Use it for credential brokering, service discovery, and proxied calls to downstream APIs.
Why use it?
It keeps service credentials away from the agent while still allowing calls to connected services.

Getting it into your agent

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 yesterday.

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 command travel with it, and installing the plugin installs all of them — 62 tokens a session between them. Each is measured on its own page, and each can be installed alone.

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.
