Implementation Reference
- src/tools/registry.ts:361-368 (registration)Registers the 'list_code' tool including its description and input schema (no required inputs). Part of the getToolDefinitions() array export.
{ name: 'list_code', description: 'List all extracted code nodes', inputSchema: { type: 'object', properties: {}, }, }, - src/tools/handler.ts:224-228 (handler)The switch case in ToolHandler.handleTool() that executes the 'list_code' tool by creating a NodeManager instance and calling its listNodes() method.
case 'list_code': const codeListManager = new NodeManager(this.workflowsPath); await codeListManager.initialize(); return await codeListManager.listNodes(); - src/nodes/manager.ts:565-633 (helper)The core implementation in NodeManager.listNodes() that loads metadata from .metadata.json, groups extracted nodes by type (code, prompt, sql, etc.), formats a detailed list output grouped by type with icons and file paths, and returns it in MCP content format.
async listNodes(): Promise<any> { const metadata = await this.loadMetadata(); let output = '📚 Extracted Nodes Library\n\n'; // Group by type const byType: Record<NodeType, any[]> = { code: [], prompt: [], sql: [], template: [], json: [] }; for (const [workflowName, nodes] of Object.entries(metadata)) { for (const node of nodes as any[]) { byType[node.nodeType as NodeType].push({ ...node, workflowName }); } } // Display by type if (byType.code.length > 0) { output += '📜 Code Nodes\n'; for (const node of byType.code) { const icon = node.subType === 'python' ? '🐍' : '☕'; output += ` ${icon} ${node.nodeName} (${node.workflowName})\n`; output += ` 📁 ${node.filePath}\n`; } output += '\n'; } if (byType.prompt.length > 0) { output += '💬 Prompt Nodes\n'; for (const node of byType.prompt) { const icon = node.subType === 'openai' ?
