What is MCP (Model Context Protocol)?
The Model Context Protocol is an open standard that enables AI models to securely connect with external data sources, tools, and services. MCP servers expose capabilities (tools, resources, prompts) that MCP clients — like Claude Desktop, Cursor, and other AI applications — can discover and use at runtime.
Think of MCP as a “USB-C for AI” — a universal connector that lets any AI app talk to any tool or data source without custom integrations for each pair.
Why MCP Tools Matter
- Universal compatibility — one MCP server works with any MCP-compatible client
- Secure by design — sandboxed tool execution with explicit permission controls
- Composability — chain multiple MCP servers together for complex workflows
- Open standard — backed by Anthropic and a growing ecosystem of contributors
- Rapidly growing — thousands of community-built servers for databases, APIs, file systems, and more
Types of MCP Tools
