Core Concepts

MCP Servers (Model Context Protocol)

Copilot CLI includes GitHub MCP server by default. Add custom MCP servers:

bash

/mcp add             # Interactive configuration
/mcp show            # List configured servers
/mcp edit <name>     # Modify existing server

Config stored in:

~/.copilot/mcp-config.json

Skills

Skills enhance Copilot's task performance with instructions and scripts.
