thalamus@1.4.6
Mobile and Web client for Claude Code
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a dangerous cloud-controlled agent capability with credential handling, but the source shows user-invoked activation and no confirmed malicious install hook, secret theft, or broad automatic control-surface mutation.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
A user authenticates and runs the Thalamus CLI or its connect command.
Impact
A compromised or untrusted service could cause configured MCP commands to run in the user's Claude session; uploaded OAuth tokens are entrusted to that service.
Mechanism
Remote MCP command injection and explicit OAuth-token upload.
AI rationale
This is a dangerous cloud-controlled agent capability with credential handling, but the source shows user-invoked activation and no confirmed malicious install hook, secret theft, or broad automatic control-surface mutation.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package fetches enabled MCP configurations from its service and passes their command, arguments, and environment into a Claude session.
- Its connect command obtains Anthropic OAuth tokens and uploads them to the package service.
- The install hook extracts bundled archives into the package's tools directory.
Evidence against
- The install hook only unpacks bundled local archives; it does not contact a network service or alter agent configuration.
- The remote MCP configuration and credential upload occur only after the user runs the CLI and authenticates.
- No self-dependency or automatic foreign AI-agent configuration write was found.
