What Is MCP?
Model Context Protocol
MCP (Model Context Protocol) is an open standard by Anthropic that lets AI agents connect to external tools, data sources, and services through a unified protocol. Think of it as USB-C for AI — one standard interface that connects any AI model to any tool.
How MCP Works
Before MCP, every AI tool integration was custom — different APIs, different formats, different authentication. MCP standardizes this with a client-server architecture: AI apps (Claude Code, Cursor) are MCP clients; tools (databases, APIs, file systems) are MCP servers.
MCP servers expose three things: resources (data to read), tools (actions to take), and prompts (templates to use). A Postgres MCP server might expose resources (tables, schemas) and tools (run query, create table).
Key Concepts
- MCP Server — A service that exposes tools, resources, and prompts to AI clients via the MCP protocol
- MCP Client — An AI application (Claude Code, Cursor) that connects to MCP servers to access external capabilities
- Tool — An action the AI can take through MCP — run a query, send a message, create a file

Frequently Asked Questions
Do I need MCP to use AI tools?
No, MCP is one approach to tool integration. Many AI tools use direct API calls or custom integrations. MCP is valuable when you want standardized, reusable connections across multiple AI clients.
What AI tools support MCP?
Claude Code, Cursor, Windsurf, and several other AI coding tools support MCP. The ecosystem is growing rapidly as more tools adopt the standard.
