hostinger-api-mcp@2.17.1

MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The configurable API destination and bearer-token forwarding create a conditional credential exposure risk. The default endpoints are Hostinger services, so the source supports a warning rather than a publish block.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

A user runs the server and makes an API request while API_BASE_URL points to a non-Hostinger endpoint.

Impact

The configured recipient may receive the Hostinger access token. This is a conditional credential exposure risk, not evidence of covert theft.

Mechanism

The runtime combines the configured base URL with an API path and places the OAuth bearer token in the request's Authorization header; source shows no destination allowlist.

Decision evidence

public snapshot

AI called this Suspicious at 90.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The runtime accepts API_BASE_URL, defaulting to Hostinger's API, without a visible destination restriction.
The runtime sends its bearer token in the Authorization header on API requests.
OAuth defaults to Hostinger's issuer but accepts OAUTH_ISSUER; it can return a saved access token and exchanges login codes with the selected issuer.
