GitHub Copilot CLI MCP Configuration Management

Configure MCP servers for GitHub Copilot CLI using the mcp-config.json file, which uses different syntax from VS Code's mcp.json.

Configuration Location

Default: ~/.copilot/mcp-config.json

Custom location: Set XDG_CONFIG_HOME environment variable to redirect configuration directory.

# In ~/.zshrc or ~/.bashrc
export XDG_CONFIG_HOME="/path/to/your/config"

Additional config at runtime: Use the --additional-mcp-config flag to load extra MCP configuration files alongside the default:

copilot --additional-mcp-config /path/to/extra-mcp-config.json
