MCP server for Hostinger API

AI Security Review

scanned 2mo ago · by lpm-firewall-ai

No concrete malicious install-time behavior or exfiltration was found, but agent-facing setup executes an unpinned remote package with access to Hostinger credentials. This is a first-party agent-extension lifecycle risk that warrants a warning.

Static reason

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

Trigger

An agent follows skills/headless/entry/skill.md, or the Gemini extension launches its MCP server.

Impact

A later @hostinger/mcp release can execute in the user's agent environment and access the supplied Hostinger token.

Mechanism

Remote npm package execution through npx.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

The included agent skill instructs a coding agent to download and run a remote bootstrap script.
That bootstrap runs npx with @hostinger/mcp@latest, allowing an unpinned remote release to be downloaded and executed.
The Gemini extension also launches the separate @hostinger/mcp package through npx.

Evidence against

package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
The main MCP runtime uses Hostinger OAuth and API endpoints; no secret exfiltration or unrelated endpoint was found.
The bootstrap is not an npm lifecycle entrypoint and is activated only by an agent following the included skill.

17- new — a prompt with no project (empty CWD)

18- connect — an existing frontend not yet on Hostinger

19- iterate — a project already deployed to Hostinger (`.hostinger/site.json` present)

21The bootstrap only verifies the MCP and signs you in, so it is safe to run in every case (an existing session just reports `logged_in`).

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

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