• src/index.ts:512-524 (handler)

  MCP tool handler for 'generate_readme': analyzes the project and calls generateReadme to produce the README content.
  case "generate_readme": { const { projectPath } = args as { projectPath: string }; const analysis = await analyzeProject(projectPath); const readme = generateReadme(analysis.projectData); return { content: [ { type: "text", text: readme, }, ], }; }
• src/index.ts:235-373 (handler)

  Core handler function that generates the formatted README.md content from analyzed project data, including badges, sections, code blocks, and structure.
  function generateReadme(projectData: any): string { const { projectName, description, version, author, license, homepage, repository, scripts, dependencies, devDependencies, detectedTechnologies, configFiles, directoryStructureFormatted, } = projectData; let readme = ""; readme += `# ${projectName}\n\n`; const badges: string[] = []; if (version) badges.push( ``, ); if (license) badges.push( ``, ); if (detectedTechnologies.includes("Node.js")) badges.push( ``, ); if (detectedTechnologies.includes("TypeScript")) badges.push( ``, ); if (detectedTechnologies.includes("Python")) badges.push(``); if (detectedTechnologies.includes("Rust")) badges.push(``); if (detectedTechnologies.includes("Go")) badges.push(``); if (badges.length > 0) { readme += badges.join(" ") + "\n\n"; } if (description) { readme += `## 📝 Description\n\n${description}\n\n`; } if (detectedTechnologies.length > 0) { readme += `## 🛠️ Technologies Used\n\n`; detectedTechnologies.forEach((tech: string) => { readme += `- ${tech}\n`; }); readme += `\n`; } readme += `## 📦 Installation\n\n`; if (dependencies.length > 0 || devDependencies.length > 0) { readme += `\`\`\`bash\n`; if (detectedTechnologies.includes("Node.js")) { readme += `npm install\n`; } else if (detectedTechnologies.includes("Python")) { readme += `pip install -r requirements.txt\n`; } else if (detectedTechnologies.includes("Rust")) { readme += `cargo build\n`; } else if (detectedTechnologies.includes("Go")) { readme += `go mod download\n`; } readme += `\`\`\`\n\n`; } else { readme += `Clone the repository and follow the setup instructions.\n\n`; } const scriptKeys = Object.keys(scripts); if (scriptKeys.length > 0) { readme += `## 🚀 Usage\n\n`; readme += `Available scripts:\n\n`; scriptKeys.forEach((script) => { readme += `\`\`\`bash\nnpm run ${script}\n\`\`\`\n`; readme += `${scripts[script]}\n\n`; }); } if (directoryStructureFormatted) { readme += `## 📁 Project Structure\n\n`; readme += `\`\`\`\n${directoryStructureFormatted}\`\`\`\n\n`; } if (dependencies.length > 0) { readme += `## 📚 Dependencies\n\n`; dependencies.forEach((dep: string) => { readme += `- ${dep}\n`; }); readme += `\n`; } if (devDependencies.length > 0) { readme += `## 🔧 Dev Dependencies\n\n`; devDependencies.forEach((dep: string) => { readme += `- ${dep}\n`; }); readme += `\n`; } if (configFiles) { readme += `## 📝 Config-files\n\n${configFiles}\n\n`; } if (license) { readme += `## 📄 License\n\n`; readme += `This project is licensed under the ${license} License.\n\n`; } if (author) { readme += `## 👤 Author\n\n`; readme += `${typeof author === "string" ? author : JSON.stringify(author)}\n\n`; } if (homepage || repository) { readme += `## 🔗 Links\n\n`; if (homepage) readme += `- [Homepage](${homepage})\n`; if (repository) { const repoUrl = typeof repository === "string" ? repository : repository.url; readme += `- [Repository](${repoUrl})\n`; } readme += `\n`; } readme += `---\n\n`; readme += `*Generated with ❤️ by README Generator MCP Server*\n`; return readme; }
• src/index.ts:443-460 (registration)

  Registration of the 'generate_readme' tool in the ListTools response, including name, description, and input schema.
  { name: "generate_readme", description: "Generate a well-formatted, visually appealing README.md file for a project. " + "This tool analyzes the project directory and automatically creates a comprehensive README with: " + "badges, emojis, proper sections (description, installation, usage, project structure, dependencies, etc.), " + "code blocks, and professional formatting.

• src/index.ts:450-459 (schema)

  Input schema for the 'generate_readme' tool, requiring 'projectPath'.
