Tools & capabilities
Ask Gemini tools 4
ask-codexSend a prompt to OpenAI Codex CLI (defaults to gpt-6-astra with automatic fallback on quota errors). Use for code review, second opinions, analysis, and AI-to-AI collaboration. Do not override the model parameter unless the user explicitly asks. Returns both human-readable text and a structured response (provider, model, sessionId, usage) via outputSchema. Calls are ephemeral by default; pass sessionId: "" on the first call to persist its Codex thread_id, then pass the returned sessionId on follow-up calls to continue the conversation.ask-codex-editSend a code edit request to OpenAI Codex CLI and get structured search/replace edit blocks back (via codex --output-schema). Codex reads the existing files (read-only) and proposes precise, applyable changes for Claude to apply. Use this when you want Codex to suggest specific code modifications to existing files rather than just analysis. Mirrors ask-gemini-edit.pingTest connectivity with the MCP serverget-usage-statsGet the current MCP server's session usage stats: total LLM calls, token totals (input/output/thinking/cached), wall time, and breakdowns per provider and per model. No data leaves your machine — counts are tracked in-memory for the lifetime of the server process. Returns both human-readable markdown and a structured JSON snapshot via outputSchema.
Grok MCP tools 4
grok_chatSend a one-shot prompt to xAI Grok and return its reply. Stateless — for multi-turn use grok_consult.grok_reviewHave Grok review a git diff. If no diff is provided, runs `git diff <base_ref>...HEAD` (default base: main). Returns a per-dimension review. Use format='json' for CI gating (verdict + scores + blockers).grok_consultContinue a conversation with Grok by replaying the full message history each call. Stateless on the server side — the caller owns the thread.grok_challengeAsk Grok to adversarially break a piece of code: edge cases, race conditions, security holes, adversarial inputs. Returns severity-ranked issues with reproductions.
