Feature & Specification Comparison
Tools & Capabilities Breakdown
Codex Control Plane MCP Tools (38)
codex_list_projects
List known Codex projects from registry, hook history, transcripts, and cached Codex state. Use this before preflight or submit when you need a project reference; later tools accept projectId, project name, or project path and return canonical projectId. Next call codex_preflight_project_run for a concrete project.
codex_list_project_chats
List chats for one project from the bounded read model. Use this to find existing threads before continuation or review. Next call codex_get_chat_status, codex_get_chat, or codex_submit_task.
codex_list_active_chats
List chats that look active from tracked, hook, transcript, or cached evidence. Use this for operator inspection, not for creating retries. Next call codex_get_turn_status or codex_get_operation_status when ids are available.
codex_search_chats
Search chat history through the MCP-owned index and safe fallback sources. Use this for discovery or recovery when ids were lost. Do not use search results as proof that a turn is still active.
