Codex

Status: beta.

Codex is different from Hermes and OpenClaw. Do not use the Hermes/OpenClaw plugin install command as the Codex setup path.

Setup

Use Regents CLI to print the Codex MCP setup:

pnpm add -g @regentslabs/cli
regents mcp export codex
regents mcp doctor --json
regents mcp tools list --json

The export command gives Codex the MCP setup needed to call Regent tools.

Runtime Harness Use

Codex can also appear as a local runtime harness for supported Regent work. In that case, regents run keeps the local Regent path available and the work command chooses the harness.

regents run
regents runtime status --json
regents runtime tools --json

When To Use Codex

Use Codex when the work benefits from code editing, local repository inspection, MCP tools, and clear file-based handoff.

Use Hermes or OpenClaw plugin install when the agent app is Hermes or OpenClaw and needs Regent tools visible inside that app.
