programs.github-copilot-cli.mcpServers

MCP server configurations written to mcp-config.json inside programs.github-copilot-cli.configDir.

Each attribute defines a server entry under mcpServers in the config file. Supported server types:

  • local — starts a local process via stdio (command, optional args, env)
  • http — connects to a remote HTTP server (url, optional headers)
  • sse — legacy HTTP with Server-Sent Events (same structure as http)

The tools field accepts ["*"] to enable all tools or a list of specific tool names.

See https://docs.github.com/en/copilot/how-tos/copilot-cli/customize-copilot/add-mcp-servers for the documentation.
