hostinger-api-mcp@2.11.0

MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The runtime permits an unrestricted API destination override while forwarding Hostinger bearer tokens, so credential exposure is a real conditional risk. The default destination is Hostinger, and the install and build signals do not establish malicious behavior.

Static reason

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

Trigger

A user invokes a tool that makes an authenticated API request while API_BASE_URL is set to another destination.

Impact

The configured destination may receive the user's Hostinger access token.

Mechanism

The runtime builds API request URLs from API_BASE_URL and includes the access token in the Authorization bearer header.

AI rationale

Decision evidence

public snapshot

AI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The runtime accepts API_BASE_URL without destination validation; otherwise it uses the Hostinger developer API.
A user tool execution can obtain an access token and attach it as a bearer token to a request built from that base URL.
Tokens can come from saved OAuth credentials or a refresh flow.
The OAuth issuer defaults to Hostinger, while also allowing an environment override.

Evidence against

The manifest defines start, build, and start:ts scripts but no install lifecycle hook.
The build script invokes the TypeScript compiler as part of an explicit build command.
The default API and OAuth destinations are Hostinger services.
