MCP (Model Context Protocol)

An open protocol by Anthropic that lets AI models connect to external tools, data sources, and services through a standardized interface.

MCP (Model Context Protocol) is an open protocol developed by Anthropic that standardizes how AI models interact with external tools and data sources. Instead of each AI application building custom integrations, MCP provides a universal connector. In the context of Mithril, agents using MCP-compatible tools can load the SKILL.md and immediately gain access to the full Mithril API — including x402 payments — through a standardized tool interface. Claude Code and other MCP-compatible agents can use Mithril without custom SDK integration.
