AI Security Review
scanned 8d ago · by lpm-firewall-aiThe source confirms default automatic indexing that can transmit project excerpts to the package's Cachly service without a separate indexing request. The service is aligned with the package's coding-memory purpose and the behavior has an opt-out, so this warrants a warning rather than a block.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
An MCP session starts with an authenticated instance; indexing runs by default unless CACHLY_AUTO_INDEX is set to false.
Impact
Project source excerpts may be disclosed to the service without a separate indexing request; the inspected code does not show a foreign recipient or a bypass of the package's intended service.
Mechanism
The indexer walks the current directory, reads matching source files, and sends file paths and excerpts to the Cachly service.
AI rationale
The source confirms default automatic indexing that can transmit project excerpts to the package's Cachly service without a separate indexing request. The service is aligned with the package's coding-memory purpose and the behavior has an opt-out, so this warrants a warning rather than a block.

Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- dist/src/index.js starts project indexing automatically during an MCP session, up to 150 files, unless CACHLY_AUTO_INDEX is set to false; it repeats after a day.
- dist/src/handlers/cache.js reads file contents and creates a path plus excerpt for each indexed file.
- When semantic indexing is available, the handler posts that excerpt to the configured Cachly semantic endpoint.
- The package identifies itself as a coding memory service, and the destination is its Cachly service; this supports product alignment but does not establish affirmative consent to automatic indexing.
Evidence against
- The indexing trigger has an explicit opt-out, and source inspection shows transfer to the package-aligned Cachly service rather than an unrelated recipient.
