The Model Context Protocol (MCP) is an open standard created by Anthropic for connecting AI models to external tools, data sources, and services. MCP provides a universal interface for tool use, enabling any AI agent to interact with any MCP-compatible server. The protocol specification includes tool discovery, execution, and context sharing, creating an interoperable ecosystem for AI agents.
Smithery is a registry and marketplace for Model Context Protocol (MCP) servers. Developers can discover, share, and deploy MCP tools for connecting AI agents to databases, APIs, file systems, and other services. Smithery provides hosted MCP servers, reducing the setup complexity for teams adopting the MCP standard.
