🛠️ 3. MCP Tools Tests (2/3 = 66.7%)

Test	Status	Details
tools/list	✅ PASS	Returns 19 available tools
tools/call - list_workflows	❌ FAIL	Expected - n8n not configured
tools/call - list_executions	✅ PASS	Proper error structure returned

**Analysis of Failures**:

**Test: list_workflows**

• Status: ❌ FAIL (Expected)
• Reason: n8n API not configured (missing N8N_HOST, N8N_API_KEY)
• Server Response:

  {
    "error": {
      "code": -32603,
      "message": "Internal server error",
      "data": "Failed to get API instance: Missing required environment variables"
    }
  }

• Verdict: ✅ Correct behavior - proper error handling for missing configuration

**Impact**: None - this is expected behavior when n8n is not configured.

Test	Status	Details

• Status: ❌ FAIL (Pre-existing issue)
• Reason: Schema mismatch - server returns templates array, test expects resourceTemplates
• Server Response:
