hostinger-api-mcp@1.47.0

MCP server for Hostinger API

AI Security Review

scanned 6d ago · by lpm-firewall-ai

The source supports a credential-forwarding warning because operator-configured destinations are not checked against the Hostinger service. The defaults are Hostinger-aligned, and the transfer requires tool use or credential refresh, so the evidence does not establish a malicious default export.

Static reason

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

Trigger

A user invokes an API tool while API_BASE_URL points to a non-Hostinger destination, or stored credentials refresh while OAUTH_ISSUER points to one.

Impact

If configured to an unrelated recipient, these requests can disclose service credentials.

Mechanism

The runtime attaches the saved access token to requests built from API_BASE_URL; OAuth refresh sends the saved refresh token to OAUTH_ISSUER. Neither setting is restricted to Hostinger.

Decision evidence

public snapshot

AI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The runtime accepts API_BASE_URL, defaults it to Hostinger, and builds API request URLs from that setting without a destination check.
Saved Hostinger access tokens are returned for API calls; saved refresh tokens are posted to the configured OAuth issuer.
API requests attach the bearer token and send the request through Axios.
Requests are activated by an MCP caller invoking a tool.
The manifest exposes the server entrypoints and lists start and build scripts; the build script runs the TypeScript compiler.
The tool list describes Hostinger API operations, and the OAuth issuer defaults to Hostinger.

Evidence against

The default API and OAuth destinations are Hostinger endpoints.
The manifest declares no install lifecycle hook; the flagged build command is reached through the build script.
