MCP Intro — USB-C of the Tool Ecosystem
Anthropic's open standard — any client connects to any server.
3 hours2 resources1 prereqs
Model Context Protocol (Nov 2024) released by Anthropic as an open standard. Goal: expose tools/data sources/prompt templates via a vendor-agnostic protocol.
Architecture:
- MCP Server — a data source/tool provider (Slack, GitHub, Postgres, filesystem)
- MCP Client — an LLM app (Claude Desktop, Cursor, Claude Code, custom agent)
- Protocol — JSON-RPC 2.0 over stdio or SSE transport
Benefit: instead of writing per-tool integration, write the MCP server once, all MCP-aware clients can use it.
Adoption: Anthropic + OpenAI + Google (2025) + 200+ open-source servers (Slack, Notion, Linear, Postgres, GitHub, Memory, Filesystem, Browser, etc.)
What you'll gain
You can explain why you'd write an MCP server and how it works.
