MCP

The server's core (`mcp_core.py`) uses `jsonschema` for input validation, which is good. No direct `eval` or `exec` on user input is observed in the provided code. However, the `server_stdio.py` configuration registers tools like `list_files` and `search_in_files` (from an unseen `tools.py` module). The provided JSON schemas for these tools only validate type (`string` for `path`) and do not prevent path traversal (`../`) or access to sensitive system files. Without strict input sanitization or robust sandboxing of the tool execution environment, this could lead to information disclosure or arbitrary file reading vulnerabilities. The `README.md` explicitly notes that for production, authentication, TLS, stricter sandboxing, and rate-limiting are required, acknowledging these security limitations.
