Episode notes
MCP as AI's Universal Adapter
- MCP (Model Context Protocol) connects large language models to external tools and systems like a universal adapter.
- It enables AI agents to interact with the real world by giving them access to tools beyond their training data.
How MCP Servers Work
- MCP servers wrap tools and expose their names, descriptions, and input structures to the AI agent.
- The agent uses this to execute tasks by calling these tools with structured inputs and returning results.
Authorize MCP Tool Use Manually
- Always have a human in the loop to authorize tool use in MCP workflows.
- Avoid fully auto-authorizing tool usage to prevent unintended or dangerous actions.
