Codex

Codex reads Remarc comments through a plugin installed from Remarc’s marketplace. The plugin gives Codex the same MCP (Model Context Protocol) tools and skill as every other agent; the MCP tools reference lists them.

Install the plugin

Open Settings > MCP Integrations > Codex and click Install. The button reads Repair when the plugin is already installed but needs fixing. The row shows the exact CLI commands it runs, with a copy button. To run them yourself:

codex plugin marketplace add metedata/remarc-agent-plugins
codex plugin marketplace upgrade remarc
codex plugin add remarc@remarc

If the Codex CLI is not installed, the Install button says so; install Codex first or run the commands in a terminal.

To verify the install, ask Codex to call remarc_list_sessions. If your sessions come back, the plugin is working.

Remove the plugin

The Codex integration is install-only: Remarc never removes anything from your Codex configuration. To get rid of the plugin, remove it in Codex yourself.

Caution

If you used Remarc with Codex before the plugin existed, older builds wrote an [mcp_servers.remarc] table into ~/.codex/config.toml. Remove that table by hand; the plugin replaces it.

Comment delivery

Comments filed to a Codex session arrive when the agent next reads them; Codex sessions cannot be woken instantly the way Claude Code sessions can. Sessions created by Codex carry a Codex origin badge in the session picker.
