@goplausible/regent-plugin-claude@1.0.0: Suspicious npm security

AI Security Review

scanned 3h ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. This is a first-party Claude Code channel/MCP extension for remote wallet chat, signing, permission relay, and x402 payments. The main unresolved risk is agent-extension lifecycle and delegated approval capability, not confirmed malware.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

User installs/enables the Claude plugin, runs /regent:setup or loads hooks, then starts/pairs the channel server.

Impact

Can relay Claude prompts/tool approval requests to a paired wallet user and request wallet signatures/payments; no confirmed unconsented install-time control-surface mutation or exfiltration.

Mechanism

Claude channel MCP server with local hook listener, wallet WebRTC relay, signing/payment tools, and explicit setup of Claude plugin permissions

Rationale

Source inspection shows a guarded, explicit Claude agent extension with broad delegated approval and wallet-signing capabilities, but no npm install-time mutation, stealth persistence, credential theft, or unapproved wallet drain. Per policy this fits warn/suspicious agent extension lifecycle risk rather than publish-block malware.

Decision evidence

public snapshot

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

Evidence for warning

commands/setup.md instructs user-invoked edits to ~/.claude/settings.json enabling channels and allowing mcp__plugin_regent_regent-channel__*.
hooks/hooks.json installs Claude hooks that POST prompt/tool events to local 127.0.0.1 hook listener via hook.port.
dist/server.js runs an MCP/channel server, writes ~/.claude/channels/regent/hook.port, relays permission_request notifications, and accepts yes/no approvals from wallet chat.
dist/server.js exposes signing and x402 payment tools that request wallet approval and can make HTTP requests/pay x402 endpoints after user approval.
dist/server.js bundled/minified code is large, but observed behavior is a Claude/Regent channel extension rather than install-time mutation.

Evidence against

package.json has no preinstall/install/postinstall hooks; prepublishOnly only cleans, typechecks, and builds before publishing.
README.md and skills/regent/SKILL.md state the wallet holds private keys and each signing/payment requires user approval.
.mcp.json registers a stdio MCP server through npx for this package rather than stealth persistence.
Network endpoints are package-aligned: liquidauth.goplausible.xyz relay, facilitator.goplausible.xyz, chain RPC/explorer URLs, and user-supplied x402 URLs.
No source evidence of credential harvesting, shell execution beyond documented Claude hook curl to localhost, destructive filesystem behavior, or remote payload loading.
