claude mcp add ask-llm -- npx -y @ask-llm/mcp
Your coding agent consults another frontier model over MCP. Independent reviews, plan debates, fresh eyes.
Claude and Codex review each other's work. The other model reads, your agent edits.
Prerequisite: at least one provider CLI installed and authenticated. The Quick Start covers that in step 1.
Run in your terminal:
# Project scope (current project only)
claude mcp add ask-llm -- npx -y @ask-llm/mcp
# User scope (all projects)
claude mcp add --scope user ask-llm -- npx -y @ask-llm/mcp Or install as a plugin (adds slash commands like /multi-review, /brainstorm, /compare, plus reviewer subagents and the opt-in continuous codex-pair review hook):
/plugin marketplace add Lykhoyda/ask-llm
/plugin install ask-llm@ask-llm-pluginsThen ask your agent: Use ask-llm ping to test the connection. A Pong! reply lists every provider it detected. Something off? Run npx @ask-llm/mcp doctor.
