Security Notes
The server handles user inputs for file paths and text for indexing/search, but sanitizes inputs for LanceDB queries to prevent injection. Communication is primarily via stdin/stdout JSON-RPC, which is local. Outbound HTTP calls to the optional MLX bridge default to localhost, limiting network exposure. No 'eval' or similar dynamic code execution found. Potential risk from `rag_index` if malicious paths are provided by the MCP host, but this is an inherent feature, not a vulnerability in the server's logic.
