The primary `Research_MCPServer.py` code is reasonably secure, avoiding direct code injection vulnerabilities. However, the client (`Chatbot_MultiMCPClient.py`) launches other MCP servers specified in `server_config.json` using `npx` and `uvx`. This means the overall security is dependent on the trustworthiness and security of these external packages (`@modelcontextprotocol/server-filesystem`, `mcp-server-fetch`). The `filesystem` server, in particular, could expose broad filesystem access to the LLM (via tool calls) if not carefully contained, posing a risk of unauthorized file operations or data leakage in sensitive directories. The `search_papers` tool creates directories and writes JSON files based on LLM-provided topics, which could lead to excessive disk usage or unintended file creation if the LLM is jailbroken, though the path sanitization helps prevent directory traversal.
