LEANN-MCP-Setup

The system utilizes subprocess calls for hardware detection and index transfer (rsync/scp/aws s3), which are controlled by the system's internal scripts and not directly exposed to untrusted user input via the API. Database interactions with SQLite (`chunk_store.py`) use parameterized queries, mitigating SQL injection. The FastAPI server (`leann_mcp_server.py`) listens on `0.0.0.0:8000` by default, which is common for development but requires network security (firewall, authentication) for production. The vision search endpoint handles file uploads, but its current implementation is a placeholder, so no actual content processing yet; future implementation will require robust validation (MIME type, size) to prevent vulnerabilities. The `config.yaml` explicitly notes the need for an API key authentication layer before production, showing awareness of security concerns.
