Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| codex_executeA | Start a new Codex session that executes a plan/task in the given workspace. Returns sessionId (keep it to send review feedback later), agent message, file changes and commands run. |
| codex_continueA | Resume an existing Codex session by sessionId with a follow-up prompt — typically review feedback that Codex should address. Preserves Codex context. |
| codex_reviewA | Ask Codex to review the uncommitted changes in a workspace (read-only sandbox, no files modified). Returns findings ordered by severity plus a sessionId usable with codex_continue. |
| codex_sessionsA | Discover Codex sessions stored locally under ~/.codex/sessions/. Returns sessionId, cwd, and last activity for each, newest first. sessionId can be passed to codex_continue to resume. Filter by cwd to find sessions from a specific workspace. |
| codex_metricsA | Roll up token/duration/failure counts from the local metrics log (~/.codex-mcp/metrics.jsonl). Set CODEX_MCP_PRICING (JSON: {inputPer1M, cachedInputPer1M, outputPer1M, reasoningOutputPer1M}) to include estCostUsd. |
| codex_batchA | Fan out N tasks across N cwds (typically git worktrees) with a bounded concurrency limit. Each task uses its own per-cwd lock, so callers must supply distinct cwds. Returns one result entry per input task in input order. |
| codex_healthA | Report installed Codex CLI version and login status. |
