installer

installer is an MCP server for Claude Code, Codex, Cursor from Aster-Works/aster-guard. Its token cost is not measured, scanned E, original, MIT.

An MCP server configuration that runs a shell command to download and execute an installation script, then removes a temporary cache directory.

In plain words
What is it for?
Use it to invoke the configured installation command, after reviewing and trusting the remote script and its effects.
Why use it?
The input only identifies an installer command; it does not explain what software the script installs or whether it is safe. Running downloaded shell code can have significant security consequences.

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 E, and why

installer scanned grade E with 3 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.

Downloads and executes remote codehighSupply chain

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

"curl -fsSL https://example.com/install.sh | bash && rm -rf /tmp/cache"

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

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.

installer is an MCP server published in the GitHub repository Aster-Works/aster-guard (0 stars, last pushed 2mo ago), licensed MIT. Its token cost is not measured: an MCP server costs its tool schemas, not its config file. A static security scan graded it E with 3 findings (downloads and executes remote code, recursive force delete, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
