This is not an MCP server. The codebase is a NestJS monorepo with a web frontend and API backend. The 'uploadDataset' tool is a NestJS HTTP controller endpoint, not an MCP tool definition. No MCP protocol implementation is visible, no tool registration via MCP SDK, no MCP transport (STDIO, HTTP, SSE), no MCP schema declarations. The McpModule exists but source is not provided. Without evidence of actual MCP tool definitions, schemas, or protocol compliance, this cannot be scored as an MCP server.

• Implement actual MCP server using @modelcontextprotocol/sdk (Node.js) with proper tool registration and schema definitions
• Expand tool description to 100 - 200 chars explaining WHAT the tool does, WHEN to use it, and what it returns
• Define complete input schema with typed properties: body (object with explicit fields like name, description, format) and file (file type with size constraints)
• Document output schema with fields like dataset_id, upload_status, row_count, and any chaining IDs needed by downstream tools
• Add error handling guidance: 'If upload fails due to invalid format, try CSV or Parquet. If file too large (>100MB), split and upload separately.'
