OpenAI Codex CLI

The Codex CLI accepts remote MCP servers over HTTP. Add Dock once and every Codex session can read, write, and seal rows.

Troubleshooting

Symptom
Fix
Codex errors with "mcp_servers: table expected"
TOML syntax. Check there's no stray [ or ] mismatch. Use toml --check or an editor with TOML linting.
Tools appear but list_workspaces errors 500
Confirm the key isn't revoked (Settings · API keys). If it's live and still 500s, file a bug via create_support_ticket with the x-request-id from the Codex log.
