MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The source confirms that saved Hostinger credentials can be sent to unrestricted operator-configured API or OAuth endpoints, so this warrants a warning. The default hosts are Hostinger-owned, the transfers are tied to API use or refresh, and the flagged build helper is not an install hook.

Static reason

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

Trigger

A caller invokes an API operation, or the runtime refreshes an expired saved session.

Impact

If an operator configures an unrelated destination, that server can receive the corresponding Hostinger credential.

Mechanism

API_BASE_URL controls the API request host, and OAUTH_ISSUER controls the OAuth host; the runtime attaches the bearer token or sends the refresh token to those destinations.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The package entrypoint starts the Hostinger MCP server and loads its tool catalog.
An MCP tool request can invoke an API operation using the supplied operation and parameters.
The API destination can be set through API_BASE_URL; the default is developers.hostinger.com.
The runtime obtains a bearer token and attaches it to API requests before sending them.
OAuth can load a saved access token and send a saved refresh token to the configured issuer.
The manifest has no install lifecycle hook; the build helper runs through the explicit build script.

Evidence against

The default API and OAuth destinations are Hostinger domains.
The credential transfer requires an API operation or OAuth refresh, and the alternate destinations require operator configuration.
The flagged build command compiles TypeScript; it is not a package lifecycle hook.
