AI Security Review

scanned 23d ago · by lpm-firewall-ai

Automatic first-party agent extension setup warrants a warning under the supplied policy. Namespace restrictions and ownership checks do not establish the broad or foreign control-surface mutation required for blocking.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source

Trigger

A local npm installation runs the postinstall hook; MCP synchronization additionally requires available endpoint and token configuration.

Impact

Agent instructions can change during dependency installation, creating a guarded extension lifecycle risk.

Mechanism

The hook stages and replaces packaged skills, then optionally fetches and installs validated MCP catalog resources with destination ownership checks.

AI rationale

Evidence

package.jsoncli/postinstall.mjscli/install-agent-skills.mjscli/install-mcp-skills.mjscli/mcp-platform-skills.mjs.agentsskills

Decision evidence

public snapshot

AI called this Suspicious at 94.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json automatically runs cli/postinstall.mjs after installation.
The postinstall hook invokes the packaged agent skill installer without a separate user command.
The installer writes staged skills into the consumer repository's command-center agent skill namespace.
When MCP configuration is available, postinstall fetches a platform skill catalog and installs it into the mainsequence agent skill namespace.
The MCP installer refuses to overwrite skill destinations it does not own.

Evidence against

The inspected installers restrict changes to package-owned skill namespaces rather than broad agent configuration.
No concrete malicious execution or covert exfiltration was established in the inspected source.
The package has no runtime self-dependency.
