Sellable Admin MCP - cross-workspace operations and fulfillment tools

AI Security Review

scanned 41m ago · by lpm-firewall-ai

LPM treats this as warn-only first-party agent extension lifecycle risk. The MCP exposes an explicit Hermes onboarding lifecycle that can invoke an external installer and persist package-owned state. No install-time execution or unconsented mutation of a foreign AI-agent configuration was found.

Static reason

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

Trigger

An MCP client explicitly calls `setup_hermes_onboarding_agent` or the Hermes lifecycle tool with an approved mutation mode.

Impact

Can provision, reconfigure, or destructively tear down a customer Hermes agent when invoked with valid approval artifacts.

Mechanism

approved external Hermes bootstrap/rollback invocation plus owned-state and token-file management

Rationale

Source inspection confirms a guarded, user-invoked agent provisioning and teardown capability rather than a malicious install-time payload. Warn because the package can control external AI-agent lifecycle resources through its MCP tools.

Decision evidence

public snapshot

AI called this Suspicious at 88.0% confidence as Dangerous Capability with low false-positive risk.

Evidence for warning

`dist/tools/hermesOnboardingAgent.js` invokes a PATH-resolved `hermes` binary with `execFile`.
Its `apply`, `rebuild`, and `disable` modes can provision or tear down customer-agent resources.
The tool writes Hermes registry, ledger, and disable-receipt state under the package-owned admin home.
`dist/tools/hermesCustomerToken.js` mints and stores customer tokens in owner-only local files.

Evidence against

`package.json` has no `preinstall`, `install`, or `postinstall` hook.
`dist/index.js` only starts an MCP stdio server; onboarding actions require an MCP tool call.
Mutation modes require approval-packet validation and immutable package SHA-256 candidates.
Secret-pattern logic redacts process output and rejects secret values in setup arguments.
