## Summary

Vrushali Paunikar, Carta’s chief product officer, warns that Model Context Protocol (MCP) alone won’t solve enterprise AI integration. MCP standardizes how AI models connect to software, but it doesn’t dictate *how* tasks should be executed—leaving users to manually refine prompts or risk errors in high-stakes workflows like finance.

Paunikar highlights that probabilistic AI models excel at flexibility but fail in deterministic tasks where precision matters. She cites Google’s 96.3% success rate when combining MCP access with task-specific instructions—a 63% token savings over standard prompting. The next challenge for SaaS lies in building ‘plugins’ or ‘skills’ that embed workflows, calculations, or interfaces *above* MCP, shifting differentiation from connectivity to execution reliability.

## Key points

- MCP standardizes AI-software connections but leaves task execution to models, risking errors in finance or audit-heavy workflows
- Google’s test showed task-specific instructions boosted accuracy to 96.3% while cutting token usage by 63%
- SaaS differentiation will shift from open MCP access to embedding deterministic logic or workflows

## Why it matters

If SaaS treats MCP as a finished product, enterprises may still face fragmented, error-prone AI workflows. The real battle is designing the ‘skills’ layer that bridges probabilistic models and rigid business rules—critical for finance, legal, and compliance.
