About:
In this video I push AI agents to the limit by giving a single executive assistant agent access to *2,000+ MCP tools* — and letting it *discover, connect, and compose them programmatically* in real time. Instead of hard‑coding tools up front, we use *programmatic tool calling + progressive tool discovery* so the agent can generate its own code, search a massive MCP server library, and build custom workflows on the fly.

You’ll see how I:
– Start from an *AI agent template* in Cursor and wire it for *MCP code execution*
– Use a scraped library of *2,000+ MCP servers* (Notion, Gmail, Slack, etc.) as a searchable tool index
– Let the agent *self‑connect* to Notion, Gmail, and Slack MCP servers with authentication
– Have the agent *read real project data* and draft a client update email across multiple tools
– Turn these ad‑hoc workflows into *reusable “skills”* (code files) to cut token usage by ~10x
– Combine *programmatic tool calling for development* with *direct tool calling for production reliability*

If you’re building *production AI agents, AI assistants, or autonomous workflows* and want to understand where *MCP, tool discovery, and code‑based tool execution* actually make sense (and where they break), this video walks through the full process, trade‑offs, and a pattern you can start using today.
