01 THE IDEA

Todd describes a forward-looking business model where agents built on String (or any platform) are exposed as MCP servers — standardized interfaces that allow AI assistants like Claude or ChatGPT to call specialized business functions. Examples he gives include 'process refunds on this SaaS app,' 'write blog posts in this style,' or any repeatable job function. The vision is a marketplace of specialized MCP servers that businesses purchase to extend their AI assistants' capabilities.

This is a developer-facing opportunity that combines the agent-building skills discussed throughout the video with the emerging MCP ecosystem. Early movers who build high-quality, reliable MCP servers for specific verticals (e.g., 'Shopify store operations,' 'legal document drafting') could establish strong positions as AI assistants increasingly consume MCP servers to extend their capabilities. The business model would be subscription-based access to the MCP server, potentially with usage-based pricing.

03 THE VERDICT

The timing is right to start building but premature to expect revenue. Todd explicitly says demand needs to grow before this becomes a real marketplace business. The best move is to build one excellent MCP server for a vertical you know deeply, distribute it for free to build reputation, and monetize once enterprise adoption of MCP-compatible AI assistants picks up. Think of it as planting a flag in 2025 for a 2026-2027 harvest.

Verdict: MAYBE — read why above. Still convinced? A vetted builder can pressure-test the scope before you commit.
