The project uses environment variables (NOTION_API_KEY, GOOGLE_SEARCH_KEY, etc.) for sensitive credentials, which is good practice. A minor risk is the `NOTION_DATABASE_ID` fallback to 'test-db-id' in `custom_tool.py` if not properly configured. The `MCPServerHTTP` for Google Search relies on an external URL (`GOOGLE_SEARCH_URL`), which introduces a dependency on a trusted external service; however, the `tool_filter` mechanism helps control allowed operations. No 'eval' or direct malicious patterns were found. Manipulating `sys.path` in `custom_tool.py` is generally safe within a controlled project context.
