Use the open IICP AI mesh from TypeScript or JavaScript without running a node

AI Security Review

scanned 13d ago · by lpm-firewall-ai

No confirmed malware or install-time attack behavior was found. The main unresolved risk is a default-on runtime self-updater that can globally reinstall the package after a user starts long-running provider commands.

Static reason

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

Trigger

User runs iicp-node serve or iicp-node mcp-gateway

Impact

Could mutate the global npm installation at runtime; otherwise behavior is package-aligned provider node, client, tunnel, and gateway functionality.

Mechanism

default-on runtime npm self-update plus network provider/gateway operations

Rationale

Static inspection shows risky runtime behaviors, especially default-on global self-update, but no lifecycle hook, hidden credential harvesting, destructive action, or off-purpose exfiltration. The risky primitives are largely explicit provider-node functionality, so this should warn rather than block as malware.

Evidence

Decision evidence

public snapshot

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

Evidence for warning

dist/updater.js performs default-on runtime self-update via spawn("npm", ["install","-g","@iicp/client@latest"]).
dist/cli.js starts auto-update timers during serve and mcp-gateway, first check within 5 minutes unless IICP_AUTO_UPDATE disables it.
dist/cli.js init can run execSync("npm install --no-save ...") after an interactive prompt for optional peers.
dist/cli.js mcp-gateway exposes user-allowed MCP tools over /v1/task to IICP directory-discovered callers.

Evidence against

package.json has no install/preinstall/postinstall lifecycle hooks.
Main import dist/index.js only re-exports SDK modules; no import-time execution observed.
Network calls are aligned with IICP directory, backend probing, npm version check, Cloudflare tunnel health, and user-configured endpoints.
Identity secrets are stored locally under ~/.iicp and public registration omits operator_secret/contact.
MCP gateway requires explicit command plus --tools/IICP_MCP_TOOLS and deny-lists shell/interpreter tool names.
Quick Tunnel spawns existing cloudflared only after explicit/serve reachability logic and never auto-installs it.
