mcport

Your MCPs deserve a better home. Migrate MCP server configurations from OpenAI Codex CLI to Claude Code in one command.

Switching from Codex CLI to Claude Code? You probably have a bunch of MCP servers configured in ~/.codex/config.toml — Slack, GitHub, Atlassian, Figma, Postman, and more. Re-adding them one by one is painful. mcport reads your Codex config, converts each MCP server to Claude Code's format, and adds them automatically.
