Critical failures across all dimensions. The MCP server exposes only 2 tools via a GET endpoint that returns minimal metadata. No input schemas are visible in the source code, tools are defined as plain JSON objects with toolName, category, and transport namespace only. No parameter descriptions, no output schemas, no error handling guidance. Tool descriptions are generic one-liners (10-20 chars) that fail to explain WHAT the tools do, WHEN to use them, or what they return. The implementation appears to be a placeholder/stub, no actual tool logic is present in the provided code. This is not a functional MCP server; it is a skeleton.

• Define explicit input schemas for both tools using JSON Schema with required parameters, types, and descriptions. Example: request-approval should declare parameters like approval_type (enum), requester_id (string), reason (string), and priority (enum: low|medium|high|urgent).
• Expand tool descriptions to 100-200 characters explaining WHAT each tool does, WHEN to use it, and what it returns. Example: 'Request approval for a workflow action. Submits an approval request to the designated approver and returns approval_id, status, and estimated_completion_time. Use this before executing sensitive operations.'
• Document output schemas for both tools. Specify fields like approval_id, status (enum: pending|approved|rejected), timestamp, and approver_name so LLMs can chain results.
• Add error handling patterns: dry-run support for request-approval, clear error messages (e.g., 'Approver not found. Available approvers: [list]'), and recovery guidance (e.g., 'Retry with a different approver or escalate to admin').
• Implement actual tool logic in the MCP server instead of returning placeholder metadata. The current GET /tools endpoint returns only transport.namespace, no actual tool execution is possible.
