email_save_attachment
Download an email attachment and save it directly to disk, returning metadata only (no base64 in the response) — avoids paying the token cost of round-tripping large attachments through the calling model. outputPath is relative to a fixed downloads directory (/home/user/.email-mcp/downloads, override with EMAIL_MCP_DOWNLOADS_DIR) and cannot escape it.
