AI Security Review
scanned 4d ago · by lpm-firewall-aiThe postinstall hook only prints onboarding instructions, but successful runtime authentication can automatically write Cachly credentials into editor configuration. This first-party agent setup capability warrants a warning; inspected source does not establish credential theft or another concrete attack.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime device sign-in or session authentication succeeds.
Impact
The token persists in editor configuration for use by the Cachly server; no unrelated recipient or confirmed credential theft was identified.
Mechanism
The server writes the token to its Cachly entry in Claude configuration and updates existing Cachly entries in Cursor and Windsurf configuration.
AI rationale
The postinstall hook only prints onboarding instructions, but successful runtime authentication can automatically write Cachly credentials into editor configuration. This first-party agent setup capability warrants a warning; inspected source does not establish credential theft or another concrete attack.

Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall script that prints onboarding instructions for a separate setup command; source does not show postinstall changing agent configuration.
- After runtime authentication, the server saves the Cachly token in Claude configuration and updates existing Cachly entries in Cursor and Windsurf configuration.
- The affected configuration entries point to this package, and credential lookup uses Cachly-specific environment variables, saved credentials, or a Cachly MCP entry.
- The reviewed handlers expose cache, context, roadmap, knowledge, and team operations using supplied tool inputs; the inspected excerpts do not establish hidden account actions.
- The runtime API defaults to api.cachly.dev, and the setup flow requests a Cachly API key after device sign-in.
Evidence against
- The configuration changes occur during runtime authentication, not in the npm postinstall script.
- The inspected credential and configuration paths are Cachly-specific; no unrelated credential recipient or concrete exfiltration behavior was established.
