What is MCP (Model Context Protocol)?

MCP is an open protocol by Anthropic that standardizes how AI models connect to external tools, data sources, and services. Think of it as USB-C for AI—a universal connector that lets any AI model talk to any tool.

Why is MCP important?

MCP solves the integration problem for AI tools. Instead of building custom connectors for each AI model + tool combination, developers build one MCP server and it works with any MCP-compatible AI client (Claude, Cursor, etc.).

How do I build an MCP server?

MCP servers can be built in Python or TypeScript using the official SDKs. A basic server exposes tools (functions the AI can call) and resources (data the AI can read). The protocol handles communication automatically.

What AI tools support MCP?

Claude Desktop, Claude Code, Cursor, Zed, and other AI coding tools support MCP. The ecosystem is growing rapidly as more developers recognize the value of standardized tool integrations.

What can MCP servers connect to?

MCP servers can connect AI to anything: databases (Postgres, SQLite), APIs (GitHub, Slack, Jira), file systems, browsers, code execution environments, and custom business tools. Popular servers exist for most common integrations.

Yes, MCP is fully open source under the MIT license. Anthropic published the specification, reference implementations, and SDKs. Anyone can build MCP servers and clients without licensing fees or restrictions.

How is MCP different from function calling?

Function calling is model-specific (OpenAI's tools, Claude's tool_use). MCP is a transport protocol that works across any model. MCP servers are reusable—build once, use with any MCP-compatible AI client.
