xerj

xerj is an MCP server for Cursor from roedyrustam/vibes-plug. Its token cost is not measured, scanned A, a copy of xerj, MIT.

An MCP server named xerj, configured to start with the `xerj mcp` command and connect to a service at a local URL. MCP is a standard way for an AI assistant to use external tools.

In plain words
What is it for?
It is for making xerj available as an external tool to an MCP-compatible coding assistant.
Why use it?
It gives the assistant a configured connection to the local xerj service, but the supplied details do not explain what that service does.

MCP server for Cursor

Written for Cursor: shipped in a Cursor plugin. Also seen: listed in .cursor/mcp.json.

Part of the vibes-plug plugin — 176 skills, 9 agents, 2 MCP servers shipped together

Installing this writes the configuration, not the program: `xerj` has to be on your PATH already, or the server will not start.

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.

Security

Grade A, and why

xerj 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 6d 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.

Origin

This is a copy

86% identical to xerj — 2 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.
