An MCP server named simulator, configured to run locally from a shell script. MCP is a standard way for an agent to connect to external tools.

It is for starting the configured simulator server in the current working directory.

The description does not say what the simulator does, so its specific benefit cannot be established.

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add corezoid/simulator-ai-plugin

Claude Code

/plugin install simulator

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

Made for: Claude Code, Codex.

Or install simulator, the plugin that ships this one along with the rest of its 21 skills, 1 MCP server.

Security

Grade A, and why

simulator 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 19d 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.

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.
