Install the Negotium multi-agent runtime and CLI with one package

AI Security Review

scanned 14d ago · by lpm-firewall-ai

The source confirms that user-vault provider keys are forwarded to the Maestro SDK, but does not establish the destination or prove theft. This leaves a conditional credential exposure risk that merits a warning rather than a block.

Static reason

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

Trigger

A caller invokes the Maestro provider with a user or vault user ID and the user has provider keys stored in the vault.

Impact

If the SDK sends these keys to a destination outside their intended provider service, they could be exposed; the inspected package source does not establish that outcome.

Mechanism

The provider reads DeepSeek, Moonshot, and GLM keys from the vault and includes them in SDK options as API key overrides.

AI rationale

Evidence

dist/mcp-factories.js

Decision evidence

public snapshot

AI called this Suspicious at 72.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

The Maestro provider reads DeepSeek, Moonshot, and GLM keys from the user vault and passes them as API key overrides to the Maestro SDK; the package source does not show the SDK’s destination.
The package has a postinstall hook, but its browser binary installer downloads a version-pinned release and checks its SHA-256 before installation.

Evidence against

The keys are supplied to the package’s Maestro provider as credentials for its agent service; no credential theft or unrelated recipient is established by the inspected package source.
The postinstall browser installer uses a fixed release URL and verifies the binary checksum before saving it under the Negotium state directory.
