What is MCP (Model Context Protocol)?

An open protocol that standardizes how AI applications provide context and tools to language models.

MCP, developed by Anthropic, defines a standard way for AI tools (like Claude Desktop or Cursor) to connect to external data sources and capabilities. Instead of every AI tool building custom integrations, MCP provides a common interface. Wire generates MCP servers for every context container automatically.
