Common questions

Is Ask Codex safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (0.9.0) reached the registry last month.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

Ask LLM

Second opinions for coding agents.

Get a second opinion on your code or plan, inside your coding assistant, using the model subscriptions you already have.

For individual developers and small teams who already use a coding assistant and pay for another model subscription: ask a different vendor's model to review your changes or challenge your plan, without API keys, copy-paste, or leaving the session.

You:    ask codex to review src/auth.ts for security issues

Codex: ⚠ verifyToken() compares tokens with === — not timing-safe (line 42) ⚠ the session cookie is missing a SameSite attribute Claude: Good catches — applying both fixes to src/auth.ts.

Install

You need Node.js 24+ on Linux or macOS. Before your first review, both your coding assistant (for example Claude Code) and the provider you will consult (for example Codex) must be installed and signed in. Ask LLM configures the connection; it does not install providers or sign you in. If a provider CLI such as Codex has never been signed in on this machine, sign in first and rerun setup.

npm i -g @ask-llm/mcp && ask-llm setup

Setup asks you to confirm each detected host and workflow. Inspect the preview, confirm your assistant's registration and workflows, decline the others, then follow any printed manual steps. Restart your assistant or start a new session in your project.

Your first review

With both Claude Code and Codex installed and signed in, open Claude Code in your project and ask:

Ask Codex to review my staged changes for bugs and missing error handling. Check each finding against the source before proposing fixes.

Working in Codex with a Claude subscription? Ask Claude instead. Choose a provider from a different vendor than your current assistant. A successful review names the reviewer and model, cites relevant code, and reports findings or says it found none. Your assistant applies changes after you decide what to accept. If the request fails, run ask-llm doctor and follow the troubleshooting guide for your selected assistant and reviewer. Warnings about providers you do not use do not require installing them or adding API keys.

For plans, try: “Ask Claude to challenge this plan: what assumptions could fail, and what simpler approach would fit our constraints?”

After an on-demand review, pair review can add ongoing feedback. Pairing requires explicit opt-in; setup leaves it off. Grok CLI supports a per-edit hook with Codex Sol by default or Claude Opus 5.5 via reviewer: claude; shell reviews cover command text only.

Supported hosts

A host is the assistant you work in; a provider is the model you consult.

Host	Experience
Claude Code	Reviews, plan critique, comparisons; isolated reviewers and opt-in per-edit pairing
Codex, Cursor, Gemini CLI	Tools and portable workflows; pairing on demand
Grok Build	Tools and portable workflows; opt-in per-edit pairing
Antigravity	Tools; setup prints a manual step for workflows
Pi 0.83.0+	Native tools and portable workflows; opt-in per-edit pairing
Claude Desktop	Tools only
OpenCode	Tools and portable workflows; setup verified with fixtures only

See host compatibility for the complete matrix and manual setup limits, including existing Codex registrations.

Supported providers

Provider	Access
Codex	Your authenticated Codex CLI/account
Claude	Your authenticated Claude Code account; consult it from a host other than Claude Code
Grok	Authenticated Grok Build, an exact Cursor model, or the explicit metered xAI API option
Antigravity	Your authenticated agy subscription; execution is off by default, and opt-in has no read-only guarantee
Ollama	Local models on your machine
Gemini	An eligible Gemini Code Assist Standard/Enterprise seat

Cursor Agent can also consult exact models from your Cursor catalog. It is a connection route, with usage governed by your Cursor plan.

Trust and cost

Review runs use read-only provider controls; the assistant you work in remains the editor. Antigravity refuses execution until explicitly enabled and cannot guarantee read-only access after opt-in. Review only material you are allowed to share with the selected provider.

Calls consume your existing provider plan's quota or follow that account's billing. Grok's xAI API is a separate, metered option requiring an API key; Ask LLM never enables billing or overage for you. Ollama supports local inference. Ask LLM sends no telemetry; provider and host data policies still apply.

Agreement between models is not proof of correctness. Validate findings against the code, tests, and your requirements. See data flow and costs and fallbacks.
