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.github.com, api.luminpdf.com
- Reads environment variables in bulk
Copies or enumerates the whole environment, which can include keys meant for other tools.
- Passes model output on without checks
Model output reaches HTML, SQL or a shell without validation.
- 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
28 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.
