Security profile
Exposure: Broad
Reaches into the environment, credential files or other agents' configuration.
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
- Talks to external services
Makes outbound requests. The hosts are listed so you can see where data goes.
api.cloudflare.com
- Runs shell commands
Spawns processes on your machine. Expected for command, browser and build tools.
- Reads or writes other agents' configuration
Touches folders such as ~/.claude, ~/.codex or ~/.cursor, which hold settings and sometimes keys.
- 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
26 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.
