Model Context Protocol (MCP) is an open protocol launched by Anthropic, aimed at standardizing the integration of AI assistants with external tools, data sources, and services. The emergence of MCP addresses a core problem in AI application development: how to enable large language models to access external capabilities safely and efficiently.
In the MCP ecosystem, servers provide specific capabilities, while clients call these capabilities based on user needs. consult-llm-mcp is a unique MCP server—it itself provides Claude Code with the ability to call other large language models.
