tabnexus

tabnexus is an MCP server for Claude Code, Codex, Cursor, Gemini CLI, OpenCode from KaichenCurry/TabNexus. Its token cost is not measured, scanned A, original, MIT.

An MCP server configuration for TabNexus, a service that runs through a Node.js program. It tells Claude Code how to start the server and which two environment settings it needs.

In plain words
What is it for?
Use it to configure TabNexus in Claude Code by supplying the agent name and MCP version, then starting its server entry point.
Why use it?
It provides the connection details needed for the coding assistant to launch and use TabNexus. Without those settings, the server cannot be started from the plugin configuration.

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

tabnexus 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 4d 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 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.
