Implementation Reference

• src/server/EnhancedMCPServerFixed.ts:767-769 (handler)

  Handler case in executeTool switch for the 'get_pattern' tool, delegating to getCurrentPatternSafe()
  case 'get_pattern': return await this.getCurrentPatternSafe();
• src/StrudelController.ts:180-205 (handler)

  Core handler logic in StrudelController.getCurrentPattern(): reads current pattern from Strudel.cc CodeMirror editor via Playwright, with caching
  async getCurrentPattern(): Promise<string> { if (!this._page) throw new Error('Browser not initialized. Run init tool first.'); // Return cached value if still valid const now = Date.now(); if (this.editorCache && (now - this.cacheTimestamp) < this.CACHE_TTL) { return this.editorCache; } const pattern = await this._page.evaluate(() => { const editor = document.querySelector('.cm-content') as HTMLElement; if (editor) { const view = (editor as any).__view; if (view && view.state && view.state.doc) { return view.state.doc.toString(); } } return ''; }); // Update cache this.editorCache = pattern; this.cacheTimestamp = now; return pattern; }
• src/server/EnhancedMCPServerFixed.ts:148-152 (registration)

  Registration of 'get_pattern' tool in getTools() array, including schema and description
  { name: 'get_pattern', description: 'Get current pattern code', inputSchema: { type: 'object', properties: {} } },
• src/server/EnhancedMCPServerFixed.ts:623-635 (helper)

  Helper method getCurrentPatternSafe() that provides fallback for uninitialized browser state
  private async getCurrentPatternSafe(): Promise<string> { if (!this.isInitialized) { // Return the last generated pattern if available const lastPattern = Array.from(this.generatedPatterns.values()).pop(); return lastPattern || ''; } try { return await this.controller.getCurrentPattern(); } catch (e) { return ''; } }
