MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The default API destination is Hostinger, but API_BASE_URL accepts an alternate base and the runtime forwards saved OAuth credentials to it without a destination restriction. This is a conditional credential exposure risk, so it warrants a warning rather than a block.

Static reason

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

Trigger

A user invokes a non-custom API tool while API_BASE_URL is configured to an alternate host.

Impact

The alternate recipient may receive a saved Hostinger session token.

Mechanism

The runtime builds the request URL from API_BASE_URL, attaches the OAuth bearer token, and sends the request without a Hostinger destination check.

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 is the MCP server in src/servers/all.js.
A client tool call can invoke the server's API-call handler.
OAuth token resolution loads saved credentials and returns an unexpired access token.
API_BASE_URL can replace the Hostinger API default.
API request URLs are built from that configurable base.
The bearer token is added to the request authorization header and the request is sent through Axios.
