Smithery Configuration

The server includes a smithery.yaml configuration file that defines:

• Server metadata and capabilities
• Connection methods (stdio and HTTP)
• Tool schemas and validation
• Security settings

Publishing to Smithery

1. Ensure your code is in a public GitHub repository
2. Add proper tags and description in smithery.yaml
3. Smithery will automatically discover and index your server
4. Users can then find and use your server through the Smithery platform

⚙️ Configuration

Environment Variables

Scan Modes

• Quick Mode: Fast static analysis using linting tools (ruff, bandit, mypy)
• Deep Mode: Comprehensive analysis including LLM-powered review

Output Formats

• Markdown: Human-readable reports with formatting
• JSON: Structured data for programmatic consumption

📚 API Documentation

Response Format

All tools return a consistent response structure:

interface AgentReport {
  issues: IssueOutput[];
  review: string;
  total_issues?: number;
  high_severity_count?: number;
  documentation_files?: number;
  error?: boolean;
}

interface IssueOutput {
  type: "maintainability" | "security" | "performance" | "compliance" | "other";
  severity: "low" | "medium" | "high";
  description: string;
  file: string;
  line: number;
  suggestion?: string;        // For maintainability/performance
