Mushi CLI: SDK setup, MCP wiring, bug triage. The bug mediator for AI-built apps: plain-English diagnosis + a ready fix, in your editor.
AI Security Review
scanned 19d ago · by lpm-firewall-aiThe package has no install lifecycle hook, and the inspected credential requests use the endpoint resolved for Mushi setup. MCP configuration changes are part of user-invoked connect setup or a separate wizard prompt, so the scanner hints do not establish malicious behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
The user runs the setup wizard or connect command.
Impact
No confirmed unauthorized credential transfer, install-time execution, or unrelated agent configuration change was found.
Mechanism
The wizard sends setup data to its resolved Mushi API endpoint and can write project-local Cursor and environment configuration during setup.
AI rationale
The package has no install lifecycle hook, and the inspected credential requests use the endpoint resolved for Mushi setup. MCP configuration changes are part of user-invoked connect setup or a separate wizard prompt, so the scanner hints do not establish malicious behavior.

Decision evidence
public snapshotAI called this Clean at 93.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json defines a CLI entry point and only build, lint, test, and typecheck scripts; it has no install lifecycle hook.
- The setup wizard runs from a CLI command and resolves its API endpoint from an explicit option, environment variable, saved configuration, or the package’s Mushi Cloud default.
- The wizard sends its setup event with the SDK key to that resolved endpoint; the optional test report uses the same endpoint and requires confirmation unless the user selects the yes mode.
- Cursor MCP configuration is written to the project’s .cursor/mcp.json during connect setup; the wizard offers this step with a separate prompt.
- The cited init and main entrypoint locations check whether MCP configuration files exist; they do not mutate them.
