Empirical security audit: 1 in 8 MCP configs expose hardcoded secrets, 30+ Q1-Q3 2026 CVEs, 78.3% attack success with 5 chained MCP servers, and Slack link-unfurling exfiltration.
Task Performance (30%) + Proactivity (20%) + Memory (15%) + Privacy (15%) + Independence (10%) + Real Usage (10%) [Social Volume = 0%].
2. Ranker Score Formula: Methodology Transparency (30%) + Coverage (25%) + Freshness (20%) + Independence (15%) + Reproducibility (10%).
3. Category Leaders: Agentic Models #1 Gemini 4 Argon High (93.1), #2 DeepSeek-V4 (92.9), #3 Grok 4.7 (92.3), #4 Llama Spark 1.3 Max (91.9); Workflow Builders #1 n8n AI Agent (85.3); Personal Agents #1 Grok Bot (88.5), #2 Scout (88.4), #3 Muse (86.9), while heavily hyped social-pump entries like Dots (#5 at 73.4) and closed chat wrappers (Claude Sonnet 5.5 at 79.6, GPT-6 Astra Max at 78.9) rank lower due to unverified autonomy claims, rate-limit throttling, and vendor lock-in.
