Section 1
The premise
Model Context Protocol (MCP) is an open standard for how AI clients talk to external tools and data sources — analogous to USB for AI tools. It cuts integration sprawl from N×M to N+M.
What AI does well here
- Letting any MCP-compatible client use any MCP-compatible server
- Reducing custom integration code per tool per AI client
- Standardizing how tools describe their capabilities to models
- Enabling community-built tool ecosystems
What AI cannot do
- Make every existing tool magically MCP-compatible — adoption takes time
- Replace good security review of any tool you connect to your AI
- Fix poorly-designed tools — MCP is plumbing, not magic
