CRITICAL VULNERABILITIES: The `save_uploaded_file` tool directly uses a user-provided `filename` with `pathlib.Path(filename).expanduser().resolve()`. This allows for arbitrary file write and path traversal, enabling an attacker to overwrite critical system files or write malicious content to arbitrary locations. The `extract_tables` tool uses `tabula-py` which executes a Java process, potentially opening a remote code execution (RCE) vector if untrusted PDF files are processed. Additionally, `npx @shinzolabs/coinmarketcap-mcp` runs an external Node.js package via `stdio` transport, introducing a dependency on a third-party executable which could have its own vulnerabilities. Reliance on LLM's 'good behavior' to prevent malicious tool arguments is insufficient.
