Tested with RepoPrompt CE 1.1.1 and its bundled Codex 0.145.0 on macOS. This also applies to later RepoPrompt CE releases while they continue to run Codex with a separate CODEX_HOME. A future release may provide a built-in import/sync feature, so check the app's release notes first.
MCP servers work in Codex CLI or the Codex desktop app, but RepoPrompt CE's Tools → MCP Servers list shows only RepoPrompt CE and a few app-specific entries.
