Single tool 'create_mcp_server' has a clear action verb and acceptable description (89 chars), but critical gaps undermine quality. Input schema is present with 3 parameters, all typed as strings with descriptions. However, the tool performs a WRITE operation (creates directories, installs software, modifies filesystem) with NO error recovery guidance, NO confirmation step, and NO idempotency markers. The description does not warn about side effects or prerequisites (uv installation, disk space). Output is unstructured text rather than a typed response object. No parameter validation constraints (e.g., project_name format, location path validation). The tool invokes subprocess commands without sanitization, creating injection risks. Missing: enum constraints, output schema documentation, destructive operation warnings, and recovery guidance for partial failures.

• Add a 'dry_run' boolean parameter (default false) to preview what will be created without executing. Return a structured JSON object with 'status', 'project_path', 'steps_completed', 'next_steps', and 'errors' fields.
• Validate project_name against regex (alphanumeric + underscore, 1-50 chars) and project_location against safe path patterns. Reject paths containing '..' or absolute paths outside allowed directories.
• Enhance description to 150-200 chars: 'Creates a new MCP server project with FastMCP, uv, and example tool. Installs dependencies, generates main.py and README. Requires ~500MB disk and uv package manager. Creates directories and modifies filesystem, use dry_run=true to preview.'
• Return structured JSON: {'status': 'success'|'partial'|'failed', 'project_path': '/abs/path', 'steps': ['Created dir', 'Installed uv', ...], 'errors': [], 'next_command': 'cd ... && source .venv/bin/activate && uv run main.py'}
• Add per-step error handling with recovery hints: 'uv installation failed on Linux. Try: curl -LsSf https://astral.sh/uv/install.sh | sh, then retry.' Classify errors as retryable (network, timeout) vs user-fixable (permissions, disk space).
