Switchboard CLI — local AI routing gateway (install: npm i -g switchboard-router; run: switchboard)

AI Security Review

scanned 4d ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. The package has a guarded AI-tool routing/MITM capability and explicit setup flows that write AI CLI configuration. No confirmed malicious install-time hijack or exfiltration chain was found.

Static reason

One or more suspicious static signals were detected.

Trigger

npm install runs postinstall runtime setup; user runs switchboard and opts into CLI tool setup or MITM routing

Impact

Warn-worthy capability to redirect selected AI tool traffic through a local Switchboard gateway; no evidence of covert persistence or credential exfiltration.

Mechanism

runtime dependency install plus user-invoked local router/MITM and AI CLI config mutation

Rationale

Source inspection supports a warn verdict for a guarded AI-agent routing/MITM capability and explicit AI CLI config mutation, not a publish block. The suspicious primitives are aligned with the package purpose and are mostly user-invoked, while postinstall is limited to package-owned runtime dependency setup.

Evidence

Decision evidence

public snapshot

AI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs postinstall node hooks/postinstall.js
hooks/sqliteRuntime.js installs sql.js and better-sqlite3 into ~/.switchboard/runtime via npm install
hooks/trayRuntime.js installs systray2 and removes legacy systray from runtime/package node_modules
app/src/mitm/server.js runs HTTPS MITM on port 443, generates CA certs, and edits /etc/hosts for AI tool hosts
app/.next-cli-build/server/app/api/cli-tools/codex-settings/route.js writes ~/.codex/config.toml and auth.json on API request
src/cli/menus/cliTools.js exposes Claude/Codex/Droid/OpenClaw quick setup actions that route tools to Switchboard

Evidence against

No install-time mutation of foreign AI agent configs found; agent config writes are behind explicit menu/API setup actions
Postinstall installs pinned runtime dependencies for package-owned ~/.switchboard runtime, not arbitrary remote code
cli.js binds to 127.0.0.1 by default and LAN exposure requires --host opt-in
Update check only queries npm registry for this package and update action prints npm install command rather than silently updating
The secret-like chunk is bundled JOSE/JWT implementation code, not a hardcoded credential
No credential harvesting or exfiltration endpoint outside package-aligned routing/update behavior found
