AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest activates a postinstall hook that modifies the consumer project's MCP configuration without affirmative consent, registering a command that launches this package. This is unconsented install-time mutation of an AI-agent control surface.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package locally with npm in a project containing package.json.
Impact
Project agent tools may launch this package's MCP server based on the modified configuration.
Mechanism
postinstall calls initProject, which adds a uidx command entry to the project-root .mcp.json and writes the updated configuration without a consent prompt.
Policy narrative
A local npm install triggers postinstall, which runs project initialization. That initializer adds a uidx MCP server command to the project's .mcp.json without prompting, creating an agent control surface automatically.
AI rationale
The manifest activates a postinstall hook that modifies the consumer project's MCP configuration without affirmative consent, registering a command that launches this package. This is unconsented install-time mutation of an AI-agent control surface.
Evidence

Decision evidence
public snapshotAI identified this as a dangerous AI-agent capability at 97.0% confidence with low false-positive risk.
Evidence for policy risk
- The manifest runs scripts/postinstall.mjs during installation.
- The postinstall hook calls initProject for the containing local project without a consent prompt.
- Setup reads or creates the project-root .mcp.json file.
- Setup adds a uidx MCP server that runs the package's uidx:mcp script, then writes the configuration.
- The install hook also installs first-party skills into project agent directories.
