MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The runtime permits an arbitrary API_BASE_URL and sends existing Hostinger bearer credentials to it, creating conditional credential exposure. Because the default is the intended Hostinger API and the source shows no automatic unrelated recipient, this 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 client invokes an API tool while API_BASE_URL points to an unrelated destination.

Impact

The configured recipient could receive the Hostinger bearer token. The default destination is Hostinger’s developer API.

Mechanism

The runtime obtains an environment or saved OAuth token, places it in the Authorization header, and sends the request to a URL constructed from API_BASE_URL.

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 an MCP server that processes client tool requests.
API_BASE_URL can override the Hostinger API default, and requests are built from that base URL without a destination allowlist.
API requests obtain bearer credentials from environment variables or saved OAuth credentials.
The runtime attaches the bearer token to the request and sends it to the constructed URL.
The default API destination is Hostinger’s developer API; the exposure depends on an operator configuring a different destination.

Evidence against

The inspected source does not show automatic credential export to a publisher-selected host; the configured default is the Hostinger API.
