SpaceCode - launch cloud dev environments with AI coding agents

AI Security Review

scanned 22h ago · by lpm-firewall-ai

Inspected source resolves the credential-redirection signal to normal authenticated requests directed by default to SpaceCode services. The similarity labels and generic network and process signals do not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review

Trigger

A user invokes the CLI, MCP server, or REPL and authenticates or makes a product API request.

Impact

No unauthorized credential transfer or other confirmed attack impact was established.

Mechanism

The clients attach the saved or supplied token to API requests; default API and login destinations are SpaceCode endpoints, while alternate endpoints are selected through configuration.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 95.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The manifest routes execution through the CLI binaries and declares ordinary runtime dependencies.
Login sends a newly obtained key to the SpaceCode app by default, and saved keys are used for authenticated API requests.
The CLI and MCP API clients default to the SpaceCode backend; the REPL profile client uses the same backend by default.
The inspected dependency snapshots identify the SDK, terminal styling library, and command parser; their inspected entrypoints show normal library behavior.

Evidence against

Scanner similarity and credential-redirection labels are not supported by the inspected source: observed credential destinations default to SpaceCode services, with alternate destinations supplied through configuration.
