Model Context Protocol: the open standard to connect LLMs and data
In one sentence Anthropic open-sources the Model Context Protocol (MCP), a JSON-RPC standard that lets AI assistants talk to tools, file systems, databases, and SaaS without per-model ad-hoc integrations.
Anthropic publishes MCP, an open protocol that lets an AI assistant talk to external data and tools: project files, databases, calendar, email, cloud services.
Before, every assistant had its own way of integrating tools: OpenAI plugin store, proprietary function calling, different formats. With MCP, you write a "server" once, and every compatible assistant can use it.
Think of USB: before, every device had its own connector, then one cable replaced them all. MCP does the same for AI integrations.
