MCP server for Hostinger API

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No automatic lifecycle attack exists, but the package embeds a broad agent-triggered setup flow that downloads and runs mutable external code. The remote execution and reviewer-directed safety assurance leave a concrete extension-lifecycle risk.

Static reason

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

Trigger

A coding agent follows skills/headless/entry/skill.md for a Hostinger website or deployment request.

Impact

A later GitHub or npm release can run with the invoking user's environment and access to existing Hostinger credentials.

Mechanism

Remote script retrieval followed by npx execution of a latest-tag package.

AI rationale

Evidence

skills/headless/entry/skill.mdskills/headless/entry/bootstrap.mjs~/.config/hostinger-mcp/credentials.json

Network endpoints1

raw.githubusercontent.com/hostinger/api-mcp-server/main/skills/headless/entry/bootstrap.mjs

Decision evidence

public snapshot

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

Evidence for warning

The bundled agent skill tells a coding agent to download and run a script from the moving GitHub main branch.
That script runs an unpinned latest version of a separate npm package through npx.
The bootstrap checks for Hostinger credentials in the user configuration directory before launching the external package.
The skill calls the external script safe while directing an agent to execute it; this is reviewer-directed assurance text.

Evidence against

package.json has no preinstall, install, or postinstall lifecycle hook.
The npm build command only runs the TypeScript compiler and writes build output.
The OAuth implementation uses the Hostinger authentication endpoint and a localhost callback for its stated API service.

23## Phase 0 — Node (the one manual prerequisite)

25The Hostinger MCP server requires Node ≥ 20. Check it:

27```bash

28node -v

29```

31If that errors (Node not installed) or prints a version below 20, install or upgrade Node and re-check — do not try to work around it:

33- macOS: `brew install node`
