Security profile
Exposure: Extensive
Reaches several sensitive areas at once. Read the list before installing.
What this server can reach, from a static read of the shipped code. Nothing was executed and nothing here is a verdict: a browser tool has to run commands and an API wrapper has to call its API. Decide what fits your setup.
Detected
- Matches a known malicious pattern
A YARA signature for malware, webshells or miners matched. Check the file before running anything.
- Reads or writes other agents' configuration
Touches folders such as ~/.claude, ~/.codex or ~/.cursor, which hold settings and sometimes keys.
- Accesses credential files
References SSH keys, cloud credential files or token stores.
- Installs itself to run later
Writes startup entries, cron jobs or state files that outlive the session.
- Contains instructions aimed at AI agents
Text in code or agent-facing files that steers a model. Worth reading before you trust it.
- Runs unpinned packages at runtime
Executes npx or uvx without a version, so a compromised upstream release would run.
Dependencies with known advisories
None found in the lockfiles and manifests checked against OSV.dev.
Left out of the profile
20 pattern matches in documentation, configuration or CI files were recorded but are not part of the profile, because they do not run when the server does. The owner dashboard lists them.
