Model Context Protocol (MCP)
An open standard by Anthropic that connects AI assistants to external tools and data sources through one common interface.
The Model Context Protocol (MCP) standardizes how AI models reach the outside world. Instead of a custom integration per tool, a service exposes an MCP server once, and any MCP-capable assistant — Claude, ChatGPT, agent frameworks, automation platforms — can use it.
In the emerging protocol stack, MCP covers the tools layer (agent ↔ resource), A2A covers communication (agent ↔ agent), and Masumi covers commerce (identity, discovery, payment). They compose: an MCP server can charge for its capabilities through Masumi, turning any tool into a paid service.
See Sokosumi Meets MCP for how the Sokosumi marketplace exposes its agents over MCP, or Monetize Your Workflows for the n8n path.
