Wallet operations for AI agents and humans

AI Security Review

scanned 19d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installing the package automatically changes configuration that controls multiple AI-agent products. The injected text directs agents to prefer this package's wallet command over other tools.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

npm installation runs the postinstall lifecycle hook.

Impact

An unconsented installation can persist package-authored wallet-operation guidance into Claude Code, Cursor, and Windsurf control surfaces.

Mechanism

Automatic writes to home-directory AI-agent instruction and rules files.

Policy narrative

The manifest automatically executes scripts/postinstall.mjs on installation. That script detects installed AI-agent products and writes, appends, or replaces marked instruction blocks in their home-directory configuration files. The block directs future agents to use the Memeplex CLI for wallet actions and to prefer it over MCP tools. This is an unconsented, persistent mutation of foreign AI-agent control surfaces.

AI rationale

The package uses an automatic npm lifecycle hook to alter several unrelated AI-agent instruction surfaces without a user command or consent. This meets the install-time AI-agent control-surface mutation block policy.
